What is the dining room table made of?
Have you tried evoo let set overnight then rub
If it's made of wood, try coca cola, just use a few drops of coca cola and clean with towel. Sometimes it really works. I have done it on my coffee table.
Hope it helps! Bushra
Try a hair dryer first to pull the moisture out from under the sealer. If that doesn’t work, you can try Howard Restore-a-finish
You can actually use your iron ( dry - no steam ) to remove the marks. My friend and I did an older table at work this way and everyone thought we got a new table. Nope, it was the same one but we got rid of all of the white marks, oiled it and made it look great! Wishing you the best.
Place a cloth over the stain. Set your iron to medium and iron over the cloth.
