How to Use Hot Vinegar to Remove Paint From Glass

Make sure the paint is dry before you remove it. If you try removing the paint from a glass or window before it's dry using vinegar you could create a smear on the glass.

Pour 2 cups of distilled white vinegar into a microwave-safe container. Heat the vinegar in your microwave for 25 to 30 seconds. Be careful when taking the vinegar out of your microwave.

Dab a cotton ball in the vinegar and then apply it to the dry paint on the glass. Depending on the thickness of the paint you should only need to rub across an area\Z two or three times.

Let the vinegar sit on the dry paint for at least five minutes if it doesn't come right off after rubbing it with the cotton ball. Apply the hot vinegar again, but with a clean paint brush this time instead of a cotton ball. Also, you may need to reheat the vinegar again.

Use a razor blade as a last resort if the paint still remains. Continue applying the hot vinegar to loosen up the paint more before using the blade, and be extremely careful not to scratch the glass.
