My friend swears by Dawn for removing spots and she always uses the clear Dawn.

The best thing I have found is ZOUT. Its actually a big bar of soap, generally located with the Hispanic soaps.
All you do is dampen the bar rub it on ur spot and toss in as usual. Takes old stains dried in stains, perspiration, everything. Its really cheap also

Its zoot not zout. I don't know how to edit previous reply

I would check the Queen of Clean website.

Mine is Zote!

Hydrogen Peroxide is great on organic stains like blood. Mayo is a grease stain. For grease I use what mechanics use to get grease off their hands and clothes. A tub of hand cleaner you can find at auto stores. You can try Ritz or Carbona color remover, then redye the shirt if the spots don't come out. Hint: When I find a clothes basic I like and wear a lot, I buy two of them. Sometimes more if it has to be washed a lot.

While on the subject of laundry stains, does anyone know what can take out black permanent marker off cotton? My grand daughter decided to destroy her sister's sock monkey I made for each of them. I haven't found anything to get it out, having tried all the suggestions...hair spray, peroxide, hand sanitizer...
