"I used 3 strips of a 100% cotton t-shirt and soaked it in 1 1/2 cups of car oil for 30 minutes before washing the shirt with 2 tablespoons one of the three dish soaps (Dawn, Everspring, and Smartly). I washed each strip for five minutes in a 1/2 gallon of water with the 2 tablespoons of the according dish soap."
