painters!!! rubbing alcohol as prep cleaner??

Naptha aka lighter fluid is great for removing sticky or gummy adhesive residue or tar from paint without harm to paint. Fairly mild solvent. Works well to clean a car before you start sanding so you don't grind the wax into the paint.
Mineral spirits is a bit stronger but safe for modern paints. Can soften old style enamels if not allowed to dry or evaporate.
Both will remove wax and grease safely and is not as light of a solvent as the alcohol.
This means it is slower to evaperate and will leave more of a oily film. This oily film is why it is slow to evaporate to begin with.
Alcohol or acetone are both very dry solvents that are better for cleaning bare metal where there is no plastic or paint to soften and create a reaction to newly applied paint or primer.
The trick is to not apply any new finish primer or paint over a unevaporated solvent. This is where you have to be careful. If you have wiped down a surface that has paint, primer or filler on it the old body coatings can be softened by the solvent and is holding onto it like a sponge and not allowing it to dry as fast as it needs to. This is what causes bad reactions.
So to keep this simple it is safer to wipe down the surface with a very dry rag of solvent and not soak the surface so it can evaporate very fast before the solvent can absorb and melt surface plastics. (paint)
I no I didn't do a very good job of explaining this but maybe its enough to help some.
