Water Mark on a Cherry Table?

I mix vinegar with olive oil and rub it in let it sit for a while then wipe off with a clean cloth. (works for me) Hope it works for you.

I have used pecans before. Break and rub in thoroughly. I have used mayonnaise or miracle whip and rub in thoroughly. Better the sooner you do it. If you do it right away, the mark goes away completely. Still good to do even later on.
