DIY Pits Stain Remover...You mix one part Dawn dishwashing liquid mixed with two parts hydrogen peroxide plus some baking soda. Scrub onto stains and do your laundry as usual. I also dabbed it on some areas where there were other stains like chocolate or something.
The armpit stain removal trick requires mixing just one part dishwashing liquid (it says Dawn, but you can probably use any brand) with two parts hydrogen peroxide, then let the mixture sit on the stain for an hour. For the worst kinds of stains, add baking soda and scrub. In no time no one would guess you were exercising in those clothes!
