If you have ever left a cold drink on a wooden table, you know that sometimes it can leave a water ring mark on the spot. This is especially annoying if a guest didn’t use available coasters and caused the water ring stains in the first place. But you can fix the damage caused by the water rings, using an unusual condiment found in your refrigerator.
First, rub the spot to completely dry it. Then cover with mayonnaise about ½” thick. Allow it to sit overnight and then ripe clean. The rings should be gone.
