Interesting....I just looked on the new jug of Regular Clorox in my laundry room and it, too, says 6% and I also looked at a jug of generic bleach from Ace Hardware and it says 5.25%. I also remember the older jugs of Regular chlorox used to say 5.25%. I wonder if Clorox has bumped up the strength of their bleach a bit so it 'whitens' better? The store I work at sells 'liquid chlorine' in both 10% (HTH brand gallons) and 12.5% (The carbouys we fill from our tank). The 12.5% is supposed to be around 14-16% when delivered, according to the company we get it from, to compensate for the loss of strenth on storage.
The plot seems to thicken the deeper we dig........
