If you spy some ugly stains on your walls, don’t despair. Chances are there’s a way to either remove those walls stains or block them from coming through paint.
Listen to BOB VILA ON CLEANING AND BLOCKING WALL STAINS or read the text below:
To clean water stains, of course you first need to locate and repair the leak. Once you’ve done that, and once the stain has dried to the touch, sand it with a medium-grade sandpaper, then use a brush to coat the spot with a good quality stain-blocking primer.
For stains from tobacco smoke or kitchen grease, add a quarter cup of trisodium phosphate, or TSP, to a gallon of water and—after you’ve donned gloves and goggles—use a sponge to remove the discoloration.
And what about squiggles from pens and magic markers—are they a lost cause? Not at all. Just dip a couple cotton balls in rubbing alcohol and, using a gentle, circular motion, wipe the stains away.
If you run up against a particularly tough stain, remember that a coat of stain-blocker combined with touchup paint can make almost anything disappear.
