The best time to remove paint from a plastic surface is when an accident occurs, as wet paint takes less time and effort to remove. First, mix liquid soap and warm water.
If that doesn't work, try vegetable oil or distilled white vinegar; this is more effective on oil-based paints, as it's less potent. Nail polish remover can help if all else fails.
For dried paint, don't rush to use highly potent solvents since they may harm your plastic surfaces. Go easy on them by trying any of the methods we've already discussed first.
If those fail to remove the paint, gently use a paint scraper. For the worst stains, use rubbing alcohol while wearing a face mask to avoid breathing in dangerous fumes.
Alcohol won’t work on oil-based paints, so use thinner in that case. However, don't leave this on plastic surfaces for too long, as it can cause permanent damage.
