Thanks ... I know where to get no frills bleach. Home Depot and Lowes and Aldi’s....All bleach seems to ship in a more concentrated form than a few years ago.

We really don't recommend any brand except Clorox. The others are not certified for health use. . . because they aren't made to the standard of the Clorox brand. The concentrations can vary by quite a bit from the 7% Sodium Hypoclorite the Clorox is sold at. It's better to use a known starting concentration than take chances with an off brand. Even Clorox increased their concentration a few years ago without warning. That's why the update to 24 capfuls to account for that change in concentration.

Thanks! I will nail down the particulars. What type of Clorox is best? You said the germicidal kind?
