In Response To: Heat Ring on Lacquered Oak Table (Neal Alexander)

A heat ring (mushrooming of the finish) will result from a hot melting of the lacquer, and can be dissolved and leveled with a solvent (like lacquer thinner) and sanded smooth and polished out. If you are referring to a water ring that has left the finish cloudy, that is the result of moisture in the finish, either directly or from a hot pan and hot pad (usually slightly damp)causing steam to enter the finish. There are several ways to remove this blush as we professionals call it. A simple, from the kitchen, method for slight situations is mayonnaise, but is not effective in serious blushes. Cigar ashes become a fine polish when mixed with mineral spirits and can slowly grind away at a thin layer of finish to remove a blush as well. We have often used a slightly alcohol dampened cloth to quickly wipe over the spot, once and leave it to air. The alcohol will allow the moisture to evaporate off with the alcohol and leave a clear finish behind, repeat after 15 minutes and then wait again, repeat as needed, till clear. The other method that is most likely to work is to use a Blush Remover, sold in a spray from woodfinishers supply, a light dusting will remove a blush after a couple applications, and may not disrupt the sheen noticeably. I have made my own blush remover with a fine mist of alcohol from a spray bottle. Work in a light broadcast and make sure no drips fall onto the finish, just a fine mist. Once the blush has been removed, allow to dry for eight hours and then polish with 0000 steel wood l if a patch appears in the sheen, with the grain only, and then wax and polish. Forget the tooth paste, that will make a mess of things, and vaseline is not likely to work either.
