How To Remove Old Yellow Stains

This is a dry cleaner’s guide to removing old yellow stains (usually caused by sweat and body oil’s aging overtime):
1) Pretreat the soiled areas with a solution of warm water and a few drops of dish soap. This will help remove any remaining oils.
2) Handwash your hat. It CANNOT go into a washing machine as the cardboard or plastic brim WILL get messed up. I have made this mistake so please don’t do this.
3) Soak your hat or garment in the hottest water you can get and powdered oxygen bleach. Let it sit overnight (oxygen bleaches require lots of time and heat to work so please be patient).
4) Let it air dry and then inspect.
5) Repeat the process if needed
You can also swap out step 3 and spray down your garment with 3% hydrogen peroxide and let it air dry. HP is also an oxygen bleach.
I hope this guide helps you remove your yellow stains!
