Bleach can be environmentally hazardous (evidently depending on its usage), and soaking your white clothes (such as white T-Shirts) in a bleach solution is said to weaken the fibers. I can't say I know the ins and outs of this. Maybe I should just use chlorine bleach to try to whiten my fast-fading white T-shirts. I noticed a non-chlorine bleach at Costco and am tempted to buy it next time I go there. I don't remember, but I figure it's oxygen based.
What do people do to whiten clothes in this way? Is chlorine bleach still the way to go?
