Working with Lead Paint: Lead paint is most commonly found in homes built prior to 1978. Make sure you cover any carpet with a taped-down tarp so the dust from the paint doesn’t get into it. Use a respirator, goggles, and shoe covers, and use a shop vac to thoroughly clean up the removed paint and dust from the floor and window sill. [16] X Research source

To remove paint from window glass, start by heating 1 cup of white vinegar in the microwave for 30-60 seconds. Next, dip a clean rag into the warm vinegar and saturate the paint with the solution. Don’t worry if the paint doesn’t come off yet! Then, saturate the paint with warm, soapy water to loosen it even more and lubricate the surface. After applying the water, run a razor blade slowly over the painted surface at a 45-degree angle. Use firm pressure, scrape in one direction, and remoisten the paint from time to time with the soapy rag so you don’t scratch the glass. Finish by rinsing the glass with fresh water and wiping it down with window cleaner. For tips on using chemical solvents to strip paint off window frames, read on!
