Those white rings are usually moisture/heat trapped in the table’s finish (often lacquer or polyurethane), not damage to the wood itself. Start with the gentlest method first:
Clean the surface
Wipe with a damp microfiber cloth and a little dish soap.
Dry completely.
Use gentle heat (works surprisingly often)
Put a clean cotton T-shirt or towel over the marks.
Use a hair dryer on medium heat or an iron on low/no steam.
Keep it moving for 10–20 seconds at a time.
Check frequently. The white haze often disappears as the moisture leaves the finish.
If marks remain: petroleum jelly or mayonnaise
Rub a thin layer onto the rings.
Leave for several hours or overnight.
Wipe off and buff.
For stubborn cloudiness
Try a small amount of white toothpaste (not gel) mixed with baking soda.
Rub lightly with a soft cloth following the grain.
Wipe clean immediately and polish.
Finish with furniture polish or wax
This evens out the sheen and protects the surface.
Avoid:
High heat directly on the table
Abrasive scrubbers
Acetone or strong solvents unless you plan to refinish it
If the finish looks cracked, sticky, or the rings don’t change at all, the coating may be permanently damaged and need refinishing.
