I have fought cosmosnot for years and I have tried almost every suggested chemical and method, but recently I discovered that I there is another way. There are more techniques, but this works for me, and my wife. Sitting cosmoline soaked whatever on the dashboard of my car on a hot day removes the junk far easier and more gently than any method that I've tried. It beats a hair dryer, heat gun, mineral spirits, paper towels, or strait elbow grease. I could never try my oven because my wife my might actually kill me. All I do is sit the item on paper towels on my dash and wipe away the cosmoline every few hours.
