Q. Is there any product or method (short of sanding) to restore worn and discolored cork-tile flooring? - D.D., Midland, Mich.
A. Sanding is the only method to fully restore cork tile, according to Doug Lux, president of the National Wood Flooring Association. As a material, cork has remarkable properties: It is an excellent insulator and soundproofer.
If sanding is out of the question, you can try to wipe, rebuff, and apply another coat of finish. While it will not take out all of the surface scratches that sanding would, it will give the floor a nice luster. Clean only with solvent-based cleaners, and test the product on a small, unobtrusive section first. For specific information, call the National Wood Flooring Association's consumer hotline at 1-500-443-9663, or visit the Web site www.woodfloors.org
Q. I've heard that if a bird feeder is withdrawn from circulation, the bird population drops. Is this true? - S.R., Bothell, Wash.
A. We don't yet know the answer to that question, says Ron Rohrbaugh of the Cornell Lab of Ornithology in Ithaca, N.Y. However, withdrawing one or a few feeders will have little impact. Bird feeders act only as a supplemental food source. Besides, wild bird feeding is such a popular hobby that birds can easily find another feeder in the neighborhood.
