O.K., so my mom never taught me how to do laundry. In fact, until recently I never used bleach. So I started to use bleach for my whites and have found that some of the are yellowing. I use Clorox. So I look at some of the labels on my clothes and they say use only non-chlorine bleach. Can someone tell what this is?? I looked at every type of bleach at the store and none of them said non-chlorine. Help!!
