It doesn't matter who your friends are. Doesn't make a difference whether they're Duponts and Rockefellers or Norm and Cliff from the corner bar. Sooner or later somebody's going to set a wet glass on your fine furniture and leave it there long enough to create a nasty white ring. So, what do you do? First, remember the stain is in the waxed finish, not the wood. Here's how to get it out. Make sure the surface is clean and dry. Then place a small amount of mayonnaise directly on the white ring. Cover the area with a piece of plastic wrap and let it sit for about 30 minutes. Remove the wrap, and lightly rub the mayo into the finish, using a nylon-scouring pad -- working with the grain. Then wipe up the remaining mayo with a soft cloth, and restore luster to the area with some lemon oil or paste wax. The white ring will be gone. And that's the On The House tip for today.
