Place the coat into a freezer for at least three hours. Freezing the coat will make the paint stain harden, which will make it easier to scrape off.
Remove the coat from the freezer.
Scrape off as much of the puffy paint as possible. Use a dull butter knife to do the scraping.
Pour 1/2 cup of liquid dish detergent in a small bowl.
Add 1/4 cup of lukewarm water to the small bowl. Use a spoon to swish the mixture around to form a layer of foam.
Dip a clean sponge into the foam. Ensure the sponge picks up just the foam and not the water.
Pat the foamy sponge onto any remaining paint residue. Blot away stains.
Allow the coat to dry completely.
Brush the recently cleaned area with a suede brush to restore the pattern of the suede.
