Tannin Spot Remover effectively removes black spots caused by tannin/water reaction. May be used on unfinished, soaped, oiled or waxed interior surfaces.
Spray Tannin Spot Remover evenly on the stain directly from the bottle.
Leave the Tannin Spot Neutralizer to dissolve the stain for 30-60 min.
Wipe with cloth wrung in lukewarm water.
Repeat operation if necessary.
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.
