To remove white rings left by wet glasses on wood furniture, mix equal parts vinegar and olive oil and apply it with a soft cloth while moving with the woodgrain. Use another clean, soft cloth to shine it up. Toget white water rings off leather furniture, dab them with a sponge soaked in full-strength white vinegar.
Place a cloth over the ring. An iron set to medium heat and iron over the cloth. I will draw the moisture out.
Hi Pat: If it's steam marks, you can just rub on some mayo (miracle whip) and let it sit for about 10 seconds and wipe it off with a wash rag. You may have to do it a couple of times, but it works:) Good luck
Pat, everyone has their own method of removing these. Here are some links for you to look over, then pick your favorite.
Thanks so much from you all, hopefully it will do the trick.
