I use color-safe bleach on my colored laundry but I finally just can't stand it. What IS it? And why am I using it? How can bleach be color-safe? Doesn't bleach... bleach things? And if this stuff doesn't bleach things, is it really bleach? Is it doing anything other than giving me something else to spend money on? If I mixed it with any of the things you mix bleach with to get nasty reactions like chlorine gas - or spontaneous combustion - would it still do those things? Or is it a completely different product altogether and only CALLED bleach because the marketers know people will buy something called bleach?
