I know all of us have ruined favorite articles of clothing with those awful green/grey oil spots from our horns. To this day, I have not found anything that will take them out. I was just speaking to a cousin of mine and she suggested using DISHWASHER liquid in the washing machine. A capful per load of laundry. Since that stuff is meant to break down grease and oil, I think I will give it a try. Has anyone else tried this with any success or found the cure for these stains?
