Doesn't modern "Coleman fuel" contain additives? I'd worry about fish-eyes or orange peel with that.
As far as I know, it is still the Naphtha based fuel that cleans with no residue. Also great for final cleaning of gas tanks before the pro-seal process.
Blowing off any debris just spreads it around unless you have a good extraction system. Vacuuming will at least remove most of the contaminants. Grease causes paint blemishes so must be removed, by wiping or sanding. Test your wiping solvent on a hidden spot to ensure it doesn't melt the primer!
I wiped away all the sanding residue with damp paper towels. Cleaned with isopropyl alcohol.
Water is nearly free and harmless to handle (dumped the excess water on my grass and it's not dead yet ). Isopropyl alcohol removes water and hydrocarbon based contamination.
