Thanks for the very helpful article. I purchased a few Scepter cans and am ready to santize and fill. I went looking for plain, household bleach, but the products I find have more ingredients than just sodium hypochlorite and water. Some of the additional ingredients are fine (sodium chloride; sodium chlorate), but I’m not sure about the others (sodium carbonate; sodium hydroxide; poly (diallyldimethylammonium chloride); and polyacrylic acid, sodium bisulfate terminated). (FYI – These are the ingredients in plain Clorox bleach – not concentrated, not splash-less, etc.) Any concerns for these not-so-plain bleach products? Particularly if I add a few drops to the water for storage and not just container cleaning? Thanks!
