In this article, you’ll find help for removing toggle bolts, expanding wall anchors, and cleaning walls.
Wall anchors are designed to spread out and grip drywall so that you can fasten various objects to it without the screws pulling free. The various types of anchors may or may not be difficult to remove, depending upon their particular design.
Toggle bolts, as shown at right, are easy to remove—you just unscrew them and let the toggle drop into the wall cavity.
On the other hand, expanding anchors that balloon out into an umbrella-like shape behind the wall surface, as shown at left, may be left behind permanently.
To hide this type of sleeve, use a hammer and a short bolt to set the sleeve further into the wall. Then just fill the surface hole with spackling compound as you would any other hole (see How to Fix Holes in Drywall.)
When ordinary cleaners don’t work, stubborn stains on plaster often can be scrubbed away with a strong solution of tri-sodium phosphate (TSP) and water or a non-phosphate substitute. Unpainted plaster is porous but generally non-soluble, so unless you really drown the wall it can take a good bath and rinse.
Drywall has a paper coating and its gypsum base is water soluble, so water can penetrate a thin coat of paint. Scrub drywall gently with a soft sponge and a mild TSP solution, and try not to use too much water. Let the drywall dry thoroughly and consider repainting with a higher-gloss paint that resists stains and is easier to clean.
