To polish your wood coffee table without harm, use a non-abrasive microfiber cloth and a gentle wood polish. Choose a polish with natural oils like beeswax or carnauba to nourish and protect the wood. Avoid products with harsh chemicals or alcohol, as they can strip the wood’s finish. Apply the polish in a circular motion, and be sure to buff it off to avoid any sticky residue. Regularly dusting and polishing will keep your table looking its best and ensure it lasts for years to come.
