Hi Flora: If these are steam stains, like from a coffee or tea cup, or a pizza, all you have to do is wipe some mayonnaise on the spot, let it sit for about 10 seconds and wipe it off. You may have to do it a couple of times, but it really works. Good luck
Thank you Betsy - Will give it a try.
Place a cloth over the water stain. An iron set to medium heat and iron over the cloth. May take a few passes.
Thank you William.
Hi flora, Tung oil will also help to brighten the wood and reduce the water stain marks. :)
