i was looking around the house for something to remove the p[paint from my brush with and i couldn't find anything then i saw this bottle of simple green and i remembered my mom using it to remove paint form one of my bros models so i took it to the paintbrush and it was very successful returning it to original color when i used it was black when i first got it, it was chestnut but it works well on cars and brushes and household stains so just a suggestion but keep it around the house
