Things You'll Need
Plastic putty knife
Do not use a metal putty knife in place of a plastic one as this may scratch and scar the underlying surface.
Do not mistake turpentine for lacquer thinner, a much harsher solvent.
Do not use an unbuffered plastic putty knife to scrape over-spray away from wood, plastic, fiberglass, or vinyl or you may scratch and scar the underlying surface.
Removing paint drips and splatters can be a tedious, difficult endeavor. Because spray paint over-spray tends to go on light and wispy, the adhesives usually do not soak into the surface and bond. If you need to remove spray paint over-spray, appropriate removal techniques are necessary to avoid causing damage to the underlying surface.
Lay the fabric flat on top of a wood board.
Apply a few drops of olive oil to the over-spray.

Wash the fabric with dish-washing detergent.

Remove as much of the over-spray as possible with a pressure washer.
