Water stains on wood leave unsightly marks and rings that diminish the appearance of the wood. Whether the water stain is on wood furniture, wood beams or any other type of wooden surface, you likely want it gone. Remove water stains promptly for best results. Several products remove water stains on wood beams and furniture.
Soak up the water if the stain is fresh. Use a soft rag to blot at the water to remove as much from the surface as possible.
Spread a moderate coating of plain, white toothpaste onto the water stain. Avoid using toothpastes with gel, bleaches or any abrasives.
Rub the toothpaste into the wood with your fingers. Allow it to dry for several hours.
Dampen a soft rag with water. Wipe down the affected area of the wood with the cloth to remove the toothpaste. Go over the area with a clean, dry cloth to remove any moisture.
Apply lemon oil and denatured alcohol if the water stain persists. Combine 3 ml (½ tsp) lemon oil and 240 ml (1 cup) denatured alcohol in a bowl. Use a clean rag to rub the mixture onto the water spot. Buff the wood dry promptly with a clean cloth.
Mayonnaise can also be used to remove water spots from wood. Spread a thick coating of mayonnaise onto the spot. Cover it with a paper towel and tamp down a bit on the paper towel to push the mayonnaise into the wood. Allow it to sit on the spot for about four hours before wiping the area clean with a damp cloth. Apply a wood polish if the affected area becomes dull during the removal process. Always test the product you are using on a small, inconspicuous area of the wood before applying it to a more noticeable area.
