Electrolysis is the way to go but never use stainless steel as an electrode, it releases chromium which is toxic.
For what it's worth, I use 1 pound of Lye, 2 cups of washing soda and 8-10 ounces of unscented Jet Dry in a 40 gallon Brute trash can 3/4 full of water. The Lye helps remove oil and paint and the Jet Dry acts as a wetting agent. This solution is less aggressive than Purple Power but it's still caustic so I do wear goggles.
The wetting agent which is preferably a sulfonated oil type of compound or a sulfated alcohol
