Heat marks and white rings on tables usually mean finish bloom from a hot dish or cup—not burned wood. Treat the finish first; sand only if color is gone.
Confirm the damage
White haze in the finish often responds to gentle heat or a light abrasive polish. Brown or black burn-in of the wood needs sanding and refinishing of that area.
Gentle heat method
Cover with a dry cotton cloth and iron on low, no steam, in brief passes. Lift and check every few seconds. Stop when the haze fades.
Polish and recoat
If haze remains, try a fine polishing compound made for furniture, then a thin coat of matching finish. Dark heat stains in the wood require sanding to clean fiber, restain, and finish.
Prevention
Trivets, hot pads, and coasters prevent most heat marks. Do not place crockpots or laptops directly on finished tops for long periods.
