How to Clean off the undercoating

[Roger Friedrich]

I was wondering if anyone has a chemical that will safely clean the cosmoline off the under side of the vehicle? I have been scraping but it's taking awhile and getting a lot of junk in my face :-[ I know sandblasting will work but I'm not taking the cab off the frame just trying to get the years of mud and some of the cosmolime off.

A bunch of aerosol cans of cheap oven cleaner and a power washer is how i do it.
A hot day will make the cleaner work better.
Get some gloves goggles mask and old clothes because you are going to have that crud all over you.

Just one addition I would make to Billyzz recommendation is to back that up with a 3000 PSI very HOT water pressure washer!
