How to Remove Water Stains From Vintage Guitars

Water can stain vintage guitars.

Vintage acoustic guitars come in a variety of woods, including mahogany, rosewood and maple. If water comes into contact with a vintage guitar, it can leave a water stain. Take special care when removing a water stain from a vintage acoustic guitar. Use oxalic acid to remove the stain and keep the wood's finish intact.

Things You'll Need

• Oxalic acid
• Soft brass brush
• Cloth
• Bowl
• Microwave

Instructions

1. Mix 10 parts water with 1 part oxalic acid in a microwavable bowl.

2. Place the bowl in a microwave and heat it for 30 seconds.

3. Dip a cloth into the mixture. Wring out the excess liquid and rub the cloth on the water stain.

4. Let the mixture sit on the stain for 1 minute.

5. Run a soft, brass brush under cold water, and rub it over the water stain.

6. Dry the guitar with a dry cloth.
