heres my problem i have a th350 mated to a 203 in the bed of my truck its filthy and greasy and i'm going to wash it with a hot pressure washer on saturday and i'd like to "pre soak" it if possible. problem is its in my truck and i don't have any way to get the bastard out. so i'd like to use something that won't eat the paint off the bed.

Soak it with a couple bottles of Dove dishwashing soap. You'll have a few bubbles :)) but you can blow them out as well.

or you can try simple green, it works pretty well.

but dollar store dishwashing soap is good too :)
