Perspective: Ebola (EVD) kills between 25% and 90% (mean of 50%) of those who contract it. COVID-19 kills between 2% and 12.3% (mean of 7.2%) of those who contract it. Influenza kills 0.07% of those who contract it.

Thus, the following statements are true:

  • Ebola (EVD) is 7 times more deadly than COVID-19
  • COVID-19 is 102 times more deadly than influenza.
  • When it comes to mortality rates, COVID-19 is 14.6 times closer to Ebola (EVD) than it is to influenza.

In light of the above, we must all –absolutely and without fail — use proper protection, containment and decontamination procedures. If you think that 6 foot rule will protect you, however, you’re sadly mistaken. Try 30 feet, and that’s only in perfectly calm air:

It has been previously determined that SARS fomites remain active for about three hours while suspended in air or gas but researchers were unsure about the range of viral debris. Bouroubia and her colleagues have determined that coronavirus-bearing droplets of all sizes can travel 23 to 27 feet from their host after emission.

Headly, C. W. (April 2, 2020). MIT researcher says the 6-feet social distancing rule isn’t enough to flatten the curve. Ladders. Retrieved from:

The CDC’s COVID-19 FAQs page contains some good information, but it’s repetitive, wordy, over-simplified and lacking detail. In short, it fails to provide the step-by-step procedures required in a COVID-19 environment, procedures that would have greatly reduced the likelihood of infection and the progression of this disease throughout the United States and the World.

IN FACT: If the general population continues to behave as they have been, then Bill Gates is right and we’re all stuck on home lock down for the next 10 weeks.

On the other hand, if everyone — and I do mean EVERYONE — starts wearing masks 100% of the time they’re outside while practicing proper protection, containment and decontamination procedures, then we could all go back to work tomorrow.


The order in which you accomplish the steps is as important as the steps themselves.

Everything is contaminated until it’s been decontaminated.

If you make a mistake, start over.

  • RED ZONE: All of outside, including the vehicles parked in your garage
  • YELLOW ZONE: A decontamination area at an entrance nearest a shower
  • GREEN ZONE: Your home’s contamination-free environment.

Before we continue, please read the User Agreement and Disclaimers. It’s up to you to do your own research, make your own decisions, and bear the responsibility while using common sense. There is absolutely zero warranty, here, implied or otherwise.

While the following steps are relatively simple and straightforward, they are not intuitive, so please read through them carefully. They’re written in the same format as used by military and civilian aviators.


  1. RED ZONE SIGN – POSTED: Place a RED ZONE – CONTAMINATED sign at all exits. This isn’t designed to instill fear, but rather a healthy respect for what’s out there, along with a reminder you shouldn’t exit your home until you’ve prepared yourself by following the proper checklist.
  2. YELLOW DECONTAMINATION ZONE – DESIGNATED: Choose one door for entering your home from outside. Entry should be on hard flooring, near a shower, with the path between them away from common living areas.
  3. YELLOW ZONE SIGN – POSTED: Designate the area “Off Limits” except for entering and exiting the home and post a sign. Use masking tape, soccer cones, or some other visual indicator of the zone, creating a radius of at least 6 feet around the entry doorway. Treat the Yellow Zone as a potentially contaminated area. If you have things in or around that area you frequently need to use, move them to another area of the home before commencing operations.
  4. LAUNDRY BASKET – PREPARED: Place a clean, all-plastic laundry basket (no fabric or wicker) in the Yellow Zone. Once clothes go in the laundry basket, they must not be re-used.
  5. SHOE BIN – PREPARED: Place one or more low-sided plastic bins for holding shoes in the Yellow Zone. Preferably, use separate bins for each person’s shoes.
  6. COAT RACK – PREPARED: Place your coat with keys and wallet on a coat rack or coat hooks near the entry. Ideally, use a simple fleece coat. They’re easily washed, dry quickly and don’t pill if you hang them to dry instead of using the dryer.
  7. CLEANING BASIN – PREPARED: This can be a large sheet pan normally used for baking, a 5 gallon bucket, or any sort of protective basin to catch soap, bleach or water drops from reaching the floor.
  8. SCRUBBING UTENSILS – PREPARED: Place an old washcloth and a long-handled scrub brush in a 1/2 qt or 1 qt plastic container. An empty tub of sour cream or potato salad will do nicely.
  9. BLEACH SOLUTION – PREPARED: Add 1 teaspoon of bleach and 3 drops of Dawn Liquid Detergent to half a gallon of water in a nice, stable bucket. Place it near the entry.
  10. ENTRY AREA – POLICED: Do not allow anyone to enter or linger near the entry area, laundry area, or within 6 feet of the path connecting the two, unless they are prepared to exit the home and return by going through decontamination procedures.
  11. SHOWER AREA – PREPARED: Ensure the bathroom door is open, the shower curtain or door is open, and you can walk straight into the shower without touching ANYTHING.


  1. PREVIOUS CHECKLIST – COMPLETE: Make sure you finish the previous checklist before coming home, contaminated, then running around contaminating your home while… You get the idea.
  2. CLEAN CLOTHES – PREPARED: Before heading out, place a complete set of in-home clothes just outside the show room, but in a clean area of the home.
  3. CLOTHES – ON: Don your normal clothes you’d wear outside, except for your shoes and jacket, which remain in the Yellow Zone.
  4. GO BAG – PACKED: Grab whatever you need while heading out, such as a smart phone, shopping list, emergency supplies for a trip, and place in a washable nylon gym bag.
  5. WATER – PACKED: Drink plenty of water before heading out, but place a couple of water bottles in that go bag, just in case.
  6. MASK – ON: Don a mask. The mask goes on before handling anything in the Yellow Zone.
  7. EYE WEAR – ON: Don protective glasses/sunglasses.
  8. SHOES – ON: Don your shoes.
  9. COAT – ON: Don your coat containing your wallet and keys.
  10. EXIT: Leave the home, enter your vehicle, and drive away. Don’t forget to shut the garage door!


  1. HOME – ENTERED: Step into the Yellow Zone and shut the door.
  2. JACKET – HUNG: Hang up jacket with keys, wallet and smart phone still in the pockets.
  3. SHOES – OFF: While keeping mask and glasses/sunglasses on your face, remove shoes and hold over the cleaning basin.
  4. SHOES – SCRUBBED: Using washcloth and/or scrub brush, clean the bottom and edges of the soles of your shoes with the mild bleach solution. Return shoes to shoe bin to dry.
  5. OUTER CLOTHES – OFF: Remove outer clothes (down to underwear) and place them gently in the laundry basket.
  6. MASK – OFF: Remove mask and place in laundry basket (cotton) or aside for separate decontamination (hard).
  8. SHOWER – ON: Start shower and wait for the water temp to stabilize.
  9. SHOWER: Step into shower. Take a deep breath, then hold it while keeping eyes closed and wetting and finger-scrubbing your hair. Before taking a breath, be sure to tilt face up and rinse thoroughly.
  10. EYEWEAR – OFF: Remove glasses/sunglasses, rinse thoroughly from all sides, and set on top of counter.
  11. SHOWER – FINISH: Continue showering normally (about 3-5 min).
  12. HOME ENVIRONMENT – ENTERED: Exit shower, towel dry, don inside clothes, and return to home environment.
  13. YELLOW ZONE FLOOR – MOPPED: Mop the hard flooring of your Yellow Zone decontamination area with 1/4 tsp bleach in half a gallon of water with 3 drops of Dawn after every entry or set of entries (for multiple people) and at least once a day.
  14. SMART PHONE – RETRIEVED, CLEANED AND RECHARGED: Without stepping into the Yellow Zone, reach over, and being careful not to stir your jacket too much, retrieve smart phone. Before laying it down or handling it, wipe it with a cotton ball or folded toilet paper square slightly dampened with 70% alcohol.


Note: This applies not only to groceries, which may have been handled by multiple COVID-19 infected people before you put it in your basket, but it also applies to any items you’ve bought outside your home and are bringing into your home. This includes your own personal items, such as your smart phone, ear buds, sunglasses, wallet, credit card, drivers license, etc. that you don’t want to leave in your jacket pockets.

The key to getting this right is remembering The Contaminated Hands Theory: After you wash your hands, the moment you touch anything from either the Red Zone or Yellow Zone, your hands are contaminated and everything they touch is contaminated. The only viable solution is to wash and/or sanitize your hands while you’re holding the item you’re sanitizing.

Before I proceed, I recommend you watch the following video, produced by a doctor. He gets most of it right, but while the doctor has had training in “sterile technique,” I’ve had CBRNE training which deals with much more severe environments. Thus, I observed several mistakes he made, about which I will comment, below. First, the video:

Immediate comments:

  • Don’t leave your groceries outside for three days. Animals or thieves will make off with them, leaving you hungry. Instead, place them in the Yellow Zone until after you’ve finish your own decontamination procedures..
  • There needs to be AIR DISTANCE between your contaminated zone, your decontamination zone and your clean zone. Not only does the line between two sides of a single table doesn’t cut it, but it fails to make use of the outstanding resource of running water. The counter to the left and right of your sink, however, are ideal, as explained in the checklist.
  • “Hasn’t been touched in a couple of days, so I can just dump them…” No. Treat everything that comes in from the outside, including yourself, as contaminated. Reports of SARS-CoV-ID longevity range between hours and weeks. Err on the side of safety and just manually decontaminate.
  • He repeatedly touches possibly contaminated items before touching clean items, like the bread bowl, thereby contaminating them. You MUST prep your areas, first, and if you fail, no worries, but do start over.
  • Don’t put the bags on the table. Their exteriors are the most contaminated. Put them on the floor, then leave them there.
  • Let’s not talk about takeout. I feel bad for the owners of restaurants, but I’m not eating out until this is resolved. I’m stuck at home, so I’m saving money by cooking at home. Best to prepare things from scratch and cook your food.

Aside from the above, it’s very good video, which is why I included it.

My approach:

  1. Don a pair of shoes or at least flip flops.
  2. Place all food in bags on the floor to the left of the sink.
  3. Sanitize the countertop to the right of the sink. Place a towel there to prevent water run-off.
  4. Fill the left side of the sink (or tub in a single-basin sink) with warm, soapy water and add 1/4 tsp bleach.
  5. Use the right side of the sink for rinsing.
  6. Remove items from the bag and give them a dunk before placing them in the right side of the sink.
  7. When the right side of the sink is full, thoroughly rinse them and place them on the countertop to the right.
  8. Periodically wash hands in the left side of the sink, rinse them thoroughly, dry them, then dry the food and containers and put it away.
  9. When finished…
  10. Drain the sink.
  11. Gather and throw away the plastic bags.
  12. Mop the floor using 1/4 tsp of bleach per half gallon of water and 3 drops of Dawn.
  13. Sanitize your shoes/flip flops at the shoe cleaning station in the Yellow Zone.
  14. Put towel into Yellow Zone laundry basket.
  15. Sanitize your counter surfaces.
  16. NOTE: If you’re sanitizing someone else’s groceries, follow the above steps, but place them in a previously sanitized plastic crate. Close top, deliver the entire crate to their doorstep, remove top. Have the recipients remove sanitized items from the crate without touching the crate. Take crate home with you when they’re done.


  1. Make a solution of 1/4 tsp bleach in half gallon of water with 3 drops of Dawn.
  2. Daily: While your computer is off, fill and wring out a sponge several times, wringing it very well the last time to eliminate any possible dripping, and run it over your keyboard.
  3. Daily: Working from least to most likely to be contaminated, and using a sponge, wipe down all countertops, the kitchen table, commonly-used interior surfaces, appliances, vacuum cleaner, broom handles, stove knobs, fridge handles and knobs, washer and dryer knobs and door handles, doorknobs, edges of doors, dresser handles, kitchen and bathroom sink and shower/tub faucets. Save your Yellow Zone entry/exit door for last.
  4. Put sponge in one of the silverware containers in your dishwasher and wash with your regular dishes.
  5. Daily: Mop the floors using the same solution.
  6. Weekly: Vacuum, but never more often than weekly, using a HEPA-rated filter. Waiting a week allows nearly all if not all of the viruses picked up by the vacuum cleaner to die. Change the bag in accordance with the vacuum cleaner’s owner’s manual.
  7. Use a HEPA-rated air filter in your HVAC system. Change at normal intervals.
  8. Frequently: Do laundry, using medium water temperature or higher and the recommended amount of soap. If your clothes can handle it, add a 1/4 tsp of bleach to the load in the bleach dispenser. If your washing machine doesn’t have a bleach dispenser, dilute it in a quart of water and add directly to the wash cycle as soon as the clothes are wet and sudsy.
  9. Wear clothes that are durable and can handle small amounts of bleach. I wear cotton, rayon and fleece, and all three seem to be doing just fine with small amounts of bleach.
  10. If possible, wear a fleece jacket, as fleece is polyester and polyester is impervious to bleach. Hang to dry. Do not use dryer as dryer causes pilling.

That’s it for the checklists. I’ll continue to update them as I see fit.



Genetic testing has already determined it came from natural sources:

“Last week, Nature Medicine published a Correspondence, “The proximal origin of SARS-CoV-2,” which Holmes co-authored, working with scientists from the department of immunology and microbiology at The Scripps Research Institute, the University of Edinburgh, Columbia University, and Tulane University.

“The research, using comparative analysis of genomic data, both proved that SARS-CoV-2 evolved naturally, and disproved the idea that it is a manufactured biological agent.

“There is simply no evidence that SARS-CoV-2 came out of a lab,” Holmes said.

Given the fact that the SARS-CoV-2 virus is the most widely studied virus in the 21st Century, exhaustively researched and analyzed by scientists, virologists, and infectious disease specialists in every country on the entire planet, I think I’m going to shun the conspiracy theories and go with the science on this one.


If China would do just one thing — read and follow the book of Leviticus in the Bible — they would in all likelihood cease being the primary origin of the World’s emerging infectious diseases.

There’s are a number of outstandingly good reasons civilized humans limit their meats to healthy animals from the following families:

  • Clupeidae – Fish that look like fish, with fins and silvery scales
  • Most birds that don’t eat carrion, but especially the Galliformes – heavy-bodied ground-feeding birds that includes turkey, grouse, chicken, New World quail and Old World quail, ptarmigan, partridge, pheasant, francolin, junglefowl and the Cracidae.
  • Bovidae – cloven-hoofed, ruminant mammals that includes bison, African buffalo, water buffalo, antelopes, sheep, goats, muskoxen, and domestic cattle.

The primary reason you should limit your meats to these groups is that most human diseases are not carried by these animals! They’re CLEAN, not only spiritually and religiously, but from a biological perspective, as well.

However, that holds true only if they’re roasted. Not burned. Roasted. The meat will turn brown via the Maillard effect, but properly roasted meat is never blackened or charred (carcinogenic). Thus, if you grill, grill SLOWLY, never on a searing hot grill.

As for the rest of a healthy diet, I recommend selecting from The World’s Healthiest Foods — 100 foods that can serve as the basis of your Healthiest Way of Eating. As they mentioned, ” Just because a food is not on our list doesn’t mean we don’t think it can be included in a diet geared towards the Healthiest Way of Eating as long as it is a whole, natural, nutrient-rich food.” Be sure to read the FAQs about the World’s Healthiest Foods below the actual list.

Naturally, you need healthy exercise, as well, both aerobics as well as weights.

For aerobics, you need to hit and hold 80% of 220 minus your age. For example, if you’re 50, that’s 220-50=170. 80% of 170 is 136. Thus, slowly (over weeks or even months) work your way up to 136 beats per minute (BPM) with a good 5-10 minute warm-up, hold it there for 20 minutes, then slowly ramp it back down during your 5-10 minute cool down.

For weights, go very slowly and plan on working your way up to moderate weight amounts by working out 3x a week for 10 weeks, starting with the very lightest weights and only bumping to the next level the next week. Your muscles can quickly ramp up to higher loads, but your joints can NOT. It takes a couple of months for them to come online! Give them time.

In fact… ” The effect of exercise on health is profound. It can protect you from a range of conditions, including heart disease, type 2 diabetes and some cancers. But the type and amount of exercise you should do changes as you age. To ensure that you are doing the right type of exercise for your age, follow this simple guide.”


The SARS-CoV-2 is spread via contact and droplets (larger than 5 microns in size) and aerosols (less than 5 microns in size). I won’t repeat the volumes of conflicting information with respect to how long it hangs around. Instead, I’ll give you four simple rules:

  • Isolate clean living areas from contaminated areas by treating where you live as “Spaceship Home!” Everyone entering your home must pass through an “airlock” decontamination area. Never wear clothes or shoes worn outside on the inside. You don’t have to wear a spacesuit, but do change your clothes, wash your hands, and if you’ve been in the presence of many others i.e. grocery shopping or at work, then take a shower.
  • Clean all commonly-used surfaces with a disinfectant (1 TBSP bleach per gallon and a 3-5 drops of Dawn) frequently.
  • Unless you’re in a known clean environment, always wash your hands before touching your face.
  • Wear a mask when in public. Yes, better masks will work better, but lesser masks still work to reduce exposure and are certainly better than nothing. Besides, as they say, they prevent hand to mouth/nose contact, which is the primary way people are infected.


I was dumbfounded when supposed “medical experts” kept saying, “Don’t use a mask. They won’t help.”

Uh… Yes, yes they will. In fact, on April 3, 2020, NPR broke the news, along with a very good article. It’s not perfect, but it is indeed very good, and includes both a video and link to the Kaiser Permanente Thrive design, as well as the Johns Hopkins Medical University design.

Links to both mask designs:

Kaiser Permanente Thrive Mask

There are two main types of masks generally used in healthcare. N95 respirators filter out 95% of airborne particles, including bacteria and viruses. The lighter surgical or medical face-masks are made to prevent spit and mucous from getting on patients or equipment.

Both types reduce rates of infection among healthcare workers, though comparisons (at least for influenza) have yet to show that one is superior to the other. One 2020 review by Chinese researchers, for example, analyzed six randomly controlled trials that included more than 9000 participants and found no added benefits of N95 masks over ordinary surgical masks for healthcare providers treating patients with the flu.

Source: Sohn, E. (March 20, 2020). DIY masks: Worth the risk? Researchers are conflicted. Medscape. Retrieved from:
Basic 3M mask with P100 filters of HEPA / MERV 17 standard.
Removes 99.97% of airborne particles 0.3 micrometers (?m) in diameter.
Eye wear reduces likelihood of ocular infiltration.

Several things work together to make this a “P100” mask, capable of blocking particles down to 0.3 micrometers (?m) in diameter 99.97% of the time:

FIT: The mask must be sized to your face. Generally, they either come in “one size fits all” or small, medium and large or short, medium and long. Proper fitting requires trial and error, along with a fit test, which is the only good way to determine if the mask is sealing properly. The documentation included in your mask describes how to conduct a fit test.

CONSTRUCTION: The mask should be made of flexible silicone rubber, with a sturdy outer shell and a flexible sealing flange. Inflow and outlet valves are quick-sealing, and usually thin discs of silicone against a smooth plastic surface.

FILTERS: Many different filters exist, and while viruses are very tiny, the size of a football compared to a football stadium, the drops of fluid containing them as expelled from a sneeze or a cough are the size of the football stadium.

We’re stopping football stadiums, not footballs. But since the football–sized SARS-CoV-2 virus is embedded in stadium-sized droplets of fluid, and cannot live in the air without those droplets, stopping the stadium-sized droplet of fluid is sufficient, which is why most hospitals treading COVID-19 patients are using N95 masks.

ULPA (Ultra Low Particulate Air): Removes 99.9995% of airborne particles 0.12 micrometers (?m) in diameter . MERV 20 equivalence. These are the highest quality filters available. ULPA filters provide better filtration for tobacco smoke, oil smoke, insecticide dust, carbon dust, and even capture some viruses. These are very expensive filters and reserved for extremely hazardous particles, fumes, and chemicals can pose a threat to the user and/or environment. Because of their density, they’re usually reserved for forced-air environmental suits powered by an electrical blower.

HEPA (High Efficiency Particulate Air): Removes 99.97% of airborne particles 0.3 micrometers (?m) in diameter. MERV 17 equivalence. Provides excellent filtration for bacteria, lung damaging dust, spores, pollen, pulverized coal, and metallurgical dust and fumes. N/R/P100 masks used in a variety of home and industrial applications meet this standard.

N95 vs P100. Subtract 95% and 99.97% from 1, and you obtain two numbers, the ratio of which comes to 1,667. The P100 mask is roughly 1,667 times better than N95 mask at blocking 0.3 micron or larger contagions. ‘Nuff said.

ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers): Removes 95% of airborne particles 0.5 micrometers (?m) in diameter. MERV 15 equivalence. Captures bacteria, pollen, spores, and other harmful particulates. The N95 mask used by medical personnel in hospitals treating COVID-19 patients meets this standard.

Now, a number of otherwise well-educated and even smart people continue saying, “masks aren’t effective.”

Of course they’re effective. Why do you think medical staffers are wearing them? The question is, just how effective are they?

Even a 100% cotton surgical mask is 80% effective. When two people are together and both are wearing a surgical mask, that jumps to 96%, better than the N95 mask alone, and the same as two N95 masks taken together.

Wear a mask, people. Wear the right mask and you’ll reduce your chances of contracting COVID-19 between 80% and 99.997%.

NOTE (4/4/2020): This continues to be a work in progress. It contains enough information to be as is, but I will continue to update it frequently.

Sew Your Own Surgical Mask:

Yes, a kind lady has published a simple but effective pattern for anyone with a sewing machine (or patience and a needle and thread) to make their own surgical mask. You’re looking for a surgical mask with a top tie, bottom tie, and pleated fabric in the front that accepts the bulge of your chin and nose while remaining snug around the edges.

Additional recommendations:

  • Sew it so that it minimizes the free air space inside the mask. It will simply balloon and prevent proper air exchange. You want the inside layer to lay snugly (not tightly) against your nose, lips and chin.
  • Use two layers of a 100% cotton white t-shirt material or tightly woven pillow case material.
  • This pattern is for an around-the-ear loop design. I made one that tied behind my head and behind my neck like an actual surgical mask. But I didn’t have elastic material. If you do and you want to to make an around-the-ear design, go for it. I don’t think they’re as secure, though.
  • Mark the inside and never wear it inside out, particularly after having been in public. That’s as bad as touching your face.
  • Wash the mask along with your outdoor clothes in warm or hot water, normal amount of soap, and a 1/4 tsp of bleach. Dry normally. NEVER hand-wash it. It just won’t get it anywhere near as clean as using the machine.
  • Make two! That way, if you have to make two trips, you don’t have to wash and wait before going out again.
  • If you do go out to multiple stops, put the mask on before exiting the car at your first stop and leave it on until you re-enter the vehicle after your last stop, then toss it in the back and do not reuse until after you’ve washed it. Carry your spare mask in your purse.
  • Wear glasses at all times. They help guard your eyes from free-floating particles or spittle from others talking floating into your eyes.
  • Combine wear of the mask with social distancing, frequent hand-washing, and proper CCA procedures.



Members of the military receive extensive initial and periodic refresher training in Chemical, Biological, Radiological and Nuclear Environments (CBRNE). This training includes the nature of each threat, protective gear, and the pros and cons of its use in these four environments. It also includes a rather exhaustive (106) list of steps to be performed in the right order in the Contamination Control Area (CCA), which consists of five separate zones/areas (Red, Orange, Yellow, Blue and Additional), each with upwards of 4 separate stations. We use these procedures during exercises.

If you want to strain your brain, by all means, examine them here:

Impetus i.e. Reason for Adoption

The most recent information reveals cardiovascular conditions can make COVID-19 far worse, and even if you don’t have a cardiovascular condition, COVID-19 can give you one.


Generally speaking, it’s impossible to predict how well any country will come out of this until the total inactive cases (recoveries and fatalities) exceed about 20% of the total confirmed cases:

Inactive Ratio = (Recovered + Fatal) / Confirmed Cases

Currently, only five countries worldwide meet that criteria. For the other 190+ countries worldwide, things are still just getting started, and the fatality rates among confirmed cases range between about 4% for China and 10% for Italy.

Put simply, you do NOT want to get this virus. The odds of surviving it are better than surviving Russian Roulette, but not by much. Sequestration, isolation and mitigation measures have proven highly effective, provided people follow them. They must remain in place.

If everyone wears a mask and follows proper decontamination procedures, however, there’s no reason everyone has to stay at home. In fact, allowing people to go without masks or use decon procedures to get groceries and take care of loved ones is FAR more risky than allowing everyone to return to normal lives provided they wear masks and do decon.

South Korea and China have done a GREAT job of isolating people, identifying active cases and aggressively treating the victims. We can and should learn a great deal. Peck’s knee-jerk and rather heavy-handed “Shut it off!” mandate in Ghostbusters, however, was NOT the right course of action:

Sound familiar?

Bleach Concentration Chart:

Pools use 1 ppm for sanitizing the water. 20 ppm is “shock” level and will eat algae. 50 ppm will lightly bleach colors out of clothes. 100 ppm is sufficient for wiping down otherwise clean food preparation areas. 800 ppm might be required for the final cleanup after vomiting and diarrhea.

3000 ppm will destroy most clothes, can cause breathing problems if you’re in the room, and aside from a few industrial applications, is both overkill and unnecessary.

Thus, 1/4 tsp per load of laundry using soap and warm water should be all you need to sanitize your clothes, and 1 TBSP per gallon is sufficient to sanitize most surfaces.
