Oxalic acid 65160
Oxalic acid is used to remove stains and greying marks on weather-stained wood. It is also used to degrime and renew older furniture finishes and degrease oiled woods such as teak.
In a non-metal container, combine a small quantity of oxalic acid with a bit of warm water to create a granular paste. Stir with a wooden stick (do not use metal) until completely dissolved. Apply a generous amount of the mixture with a paintbrush onto the wood surface and let sit for 20 minutes. Work over the area with a nylon brush until desired effect is achieved. Rinse with clean water to neutralize the mixture. Let dry for 24 hours before applying any finishing products or applying a second coat of oxalic acid.
