If you have a wooden table or wood surface and you find white rings or spots, you should clean it immediately. These are water rings or stains caused by water minerals and when water falls on the surface of the wood, it evaporates leaving behind the mineral which causes such white rings and spots. Usually it happens when a wooden surface is not polished or varnished or wax has not been used on it. It is more susceptible to such water rings. You can clean water rings left on wood yourself or if you have an expensive wooden table or an antique then it is preferable to call in the professional cleaners.
If you are planning to clean the water rings yourself, you can use a regular toothpaste, avoid the gel based tooth pastes and dab some on a dampen piece of cloth or rag. Now wipe off the water stains using this and re-polish the surface. You can also apply lemon juice or if you want you can use vinegar instead along with salt and make a paste. Use a soft bristle tooth brush and apply this paste in a circular motion over the water ring. Then use a wet cloth to clean it up, you will see the marks that the marks have gone away.
