Tannin Spot Neutralizer


WOCA Tannin Spot Neutralizer removes black spots caused by acid/water reaction. For use on unfinished, soaped, oiled or waxed interior surfaces. Oak wood naturally contains a very high amount of tannic acid. Black spots are formed when the wood is exposed to metal and moisture.   Leaving a wet glass, or a leaky vase can trigger a chemical reaction from the acid in the wood and the water.  This reaction leaves an undesired black spot.

  1. Spray Tannin Spot Neutralizer evenly on the stain directly from the bottle.
  2. Leave to dissolve the stain for 30-60 minutes.
  3. Leave the solution to dissolve stain and dirt etc.
  4. Wipe with cloth wrung in lukewarm water.
  5. Repeat if necessary.
  6. When the floor is completely dry, apply the original surface finish, e.g. oil, wax or soap, to re-establish the protection of the surface.
