This really disturbs me, I do some of my cleaning with a Clorox/water solution and have always relied on only the brand Clorox with the blue lid to be actual bleach.
No idea why they would make this change. It makes no sense. I don’t use bleach for my laundry but I would bet I buy more of it than most people for home use.
We did a work up of the amounts of the adulterants added to the varieties of Clorox in their newly concentrated formulas. Where before we recommended a twenty to one mix, it should now be a twenty-four to one to get the same concentration that makes the Dakin's Solution. At 24:1, the other adulterants are well below any danger levels especially as you are not going to drink the stuff.
The least adulterated is the Bacteriological Clorox, designed for disinfecting. That's what we use.
