How to Remove Paint from Vinyl
If you need to remove dried paint from vinyl, try scraping it off with a plastic scraper or spatula. You can use a razor as well, but do your best to avoid scratching or cutting the vinyl. To loosen the paint, pour a small amount of mineral spirits or turpentine on a cloth and rub it on the dried paint until it starts to break down or is removed.
