Quoting this CDC source:
Note carefully that the only recommendation for rinsing takes place before sanitizing with bleach.
CAUTION: I would not personally consider attempting this with any chlorine bleach that had ANY ingredients other than sodium hypochlorite and water. And I would also not consider attempting it with any bleach more concentrated in sodium hypochlorite than 5.25%. That leaves plain old generic bleach without any other ingredient additives and/or perfumes. This may (?) eliminate Clorox from consideration.
Putting this into mg/L (ppm) perspective:
1) If we take the liberty to presume (whereby to simplify this, such that ppm and mg/L equivalence has validity) that 5.25% bleach has a density of 1.00 grams/CC (with this admittedly going to be slightly off), we can presume that 1 measuring Tablespoon delivers 15 grams of 5.25% bleach.
2) 1 Gallon of distilled water = 3,785.4 mL ~= 3,785.4 grams of water. I'm recommending distilled or very high quality RO water here.
3) 15 grams of bleach added to 3,785.4 grams of water ~= 3,800 grams total (ignoring the 0.4)
4) 15 grams of 5.25% bleach = 15 x 0.0525 = 0.7875 grams of sodium hypochlorite
4) 0.7875/3,800 = X/1,000,000
5) Solving for 'X' gives us ~207 ppm bleach in water
WARNING: Other independent sources imply that ~80 ppm bleach should be considered nominally safe as no rinse, whereby the above CDC information suggests ~207 ppm (presuming my math is nominally correct within rounding and presumptions error). To be safe it may be wise to add only 5.8 mL of 5.25% plain/generic (no other additives or ingredients) bleach to 1 gallon of distilled water.
5.8 ml ÷ 15 mL = 0.38667
0.38337 x 207 ppm ~= 80 ppm
DISCLAIMER: I personally have no idea if bleach at ANY ppm concentration is safe for no rinse sanitizing use. Nor do I know how long an exposure time is required, sans that the CDC's advice is to let it air dry fully. Consider all of this as tentative speculation, and consider applying it only at your own risk.
Quoting this CDC source:
Food surfaces that may have touched flood water.
Examples: Countertops, plates.
- Wash with soap and hot, clean water.
- Rinse with clean water.
- Sanitize in a solution of 1 tablespoon of household chlorine bleach in 1 gallon of clean water.
- Allow to air dry.
Note carefully that the only recommendation for rinsing takes place before sanitizing with bleach.
