DIY Pre-Painting Cleaner

[Bingster]

Lacking a commercial pre-painting cleaner, what is a good substitute? They're only interior window frames.

I've used lacquer thinner and brake cleaned many times successfully.

Acetone works for me.

 

I,ve read of commercial car painters using carb cleaner to clean out their sprays guns as a final cleaner so it should be fine also.

 

If there is still some older paint left on your parts-be careful as some cleaners/solvents will wrinkle /lift older paints. test on a small hidden spot.

most all finish prep that is commercial grade is a basically naphtha…  or as we call it....lighter fluid

Thanks. They are primed with 2K primer and have been sanded. By the way, do you have to lightly re-sand a surface to get to "fresh" primer? I seem to recall I saw that somewhere, or maybe on another type of paint.

Or Coleman fuel.
