You have coasters, but no one in the house seems to want to use them.
You feel across your coffee table, and you notice there are rings from cups that have been left there. A family member comments that the rings are white in color and really stand out.
You can remove most rings by rubbing some mayonnaise on the rings and let it sit for about an hour.
After an hour, gently rub off the mayonnaise using a soft dry cloth.
