I was wondering if the blue cap bleach is a specific brand or is it Clorox bleach with a blue cap on the bottle?

It's the Clorox™ brand-name with a blue cap on the bottle. Clorox uses the caps to indicate specific sub-branding. The Blue Cap indicate pure bleach without any additives. No scents, etc. You really don't want any other chemicals added. We strongly don't recommend any other brand because we DON'T know what they have in them. The Clorox™ brand has stuck with this designation for years and is reliably chemically pure.

Oh, I forgot to mention. You have to make the 20-1 solution up new every day. You can't make up a big batch and keep it. It doesn't keep beyond a few hours at best.
