Red wine spills should be cleaned from wood as soon as they occur. If the wine is not cleaned, it can leave behind stains or ruin the woods' finish. If the stain has already set, it can be difficult to remove. When attempting to remove a red wine ring from a wooden table, ammonia is the first product you should try. If ammonia does not remove the stain, it is deeply set and a fine abrasive cleaner will need to be used.
Dampen the corner of a soft cloth with ammonia.
Rub the cloth lightly into the red wine ring. Continue rubbing until the stain is removed.
Dampen a soft cloth with water. Wipe all ammonia residue from the table. Use your preferred wood polish to clean and polish the table.
Mix one tbsp of rottenstone, one tbsp of baking soda and two tbsp of either mineral oil, linseed oil or lemon oil. Rottenstone is a very fine abrasive commonly found in hardware and home improvement stores and paint supply stores. Stir the ingredients to form a paste with a toothpaste-like consistency. If the paste is too thin, add more baking soda; if the paste is too thick, add more oil.
Apply a quarter-sized drop of the paste onto a soft cloth. Rub the mixture into the stain, rubbing in the same direction as the wood grain. If you are unsure which direction the wood grain is going, rub your hand along the wood. Rub your hand upward, downward, to the left and to the right. Whichever directions feels the smoothest is the wood grain. Allow the paste to dry on the stain.
Dampen a soft cloth with linseed oil. Wipe the paste away from the stain using the dampened cloth. Rub vigorously to remove both the stain and the paste.
Repeat the process as needed until the stain is removed.
