Remove all of the furniture from the room where there is lead paint.
Apply non-flammable solvent or abrasive compound to a small area of the wall with a damp cloth to loosen the paint. Follow the specific instructions on the solvent or abrasive, as different products have different instructions.
Scrape the paint off with a wire brush. Brush in circular motions and take extra care around the edges of the walls to make sure you remove all of the lead paint.
Apply solvent or abrasive to another small area on the wall and scrape the paint off with a wire brush, as in steps 2 and 3.
Bag all of the paint in doubled plastic trash bags to discard. Clean all the surfaces with wet paper towels. Wet mop the floor. Use an HEPA-equiped vacuum on everything in the room.
