How do I remove the white heat marks on my dining room table?

Equal parts olive oil and vinegar and rub into the wood. I've also heard mayonnaise works.

Ashes from a cigarette or fireplace. Use with a damp paper towel.

Take some lemon oil, in a pinch you can use mayonnaise (not fat free) or olive oil. apply on the marks and let sit. Then wipe it off and buff the table with a soft cloth. It should lessen or remove the white marks. If they are severe you may have to leave it on overnight.

Yes I used veg oil on my cupboard worked well for me

I have used 1/2 cup oil(any) with 4 tablespoons of salt. The oil acts as a lubricant and the salt acts as an abrasive.

Please don't scrub that nice table with salt. It'll seriously f**k up the finish🤤. But ya, mayo works great

I have used Howard's Restore -A- Finish for such problems and the marks disappear. Available at hard ware or Home depot stores for about $9.00 a can. Comes in a variety of colors. Wear gloves. Wipe on the area with a soft cloth. Rub in direction of the wood grain. Wipe off with a 2nd soft cloth, until it is clean. Then polish with your favorite polish. Will take off white spots, cover scratches and such.

To be honest, I have tried all the above and the results were sporadic. The thing that works best for me is a blow dryer. Yes, a blow dryer. It will take some time, but it does work. The white marks come from the heat from cups, pizza boxes, platters etc. trapping moisture in the finish of the table top. The blow dryer directed at the spot will dry out the moisture. This takes a LONG time as each spot is done individually and some spots are denser than others. Have patience, it does work.

Use a hot steam iron with a clean dry cotton cloth. Iron with the cloth between the table and the iron. White heat marks are gone. You can follow up with 50% white vinegar and 50% olive oil mixture to clean and preserve the wood table top.

I have had quite good results ( removing old stains from a rather nice victorian inlaid wooden tray) with a paste made from cigarette ashe and water Friends saved up a good lot of the ashe, and it took some elbow grease, results worth it though!

1/2 and 1/2 baking soda and mayo. Make a paste and rub in circles until the mark is gone. Works on all kinds of wood. Used it on my cherry dining table several times.
