Bleach is a really powerful chemical that destroys your clothes! [Example "A" above].
I'm pretty sure you know that already. Everyone has suffered an attack of this caustic killer.
PLEASE be cautious of it. It has ruined too many of my best pieces.
My chore at home is to wash dishes and my mom always made me put bleach in the dish water. UGHHH. I hate that. That was how most of my clothes came in contact with it. But other times was accidents and colored clothes not being separated properly before the wash.
My recommendation? Do not buy bleach at all. There are great alternatives that can help keep your whites and your colors colored LOl.
