How to remove sweat stains from your hat?
any of the oxy boosters you can buy at the local store should do the trick, just make small batch and use a brush to apply, then toss em in the dishwasher (without dishes).





They even make a plastic hat form to help keep the shape.


Also works in washing machine (but works better in d/w)

Reply:I used to scrub my hat with a tooth brush and some diluted laundry soap... It always worked for me.
Reply:I put the hats in the kitchen sink in COLD water. Add a small amount of laundry detergent and swish the hats around. Let them sit in the water for about 10 minutes. Rinse hats thoroughly with COLD water and set them somewhere to dry (usually overnight). They will be fresh and clean.
Reply:try putting ammonia mixed with laundry detergent on the stains, then let it sit for like 30 min. works for pit stains on shirts too
