To remove water rings, try using a soft cloth and a small amount of toothpaste (not gel) mixed with baking soda, gently rubbing it over the ring until it fades. You can also place a cloth over the stain and run an iron on low heat over it for a few seconds to help lift the moisture. Alternatively, applying a dab of mayonnaise and letting it sit for a few hours can draw out water marks. Always test on a small area first to avoid damaging the finish.
