Stain remover for wood

This stain remover from WOCA Denmark is a ready-mixed and easy-to-use stain removal agent for dark discolourations and stains on wood. The spray effectively removes black spots caused by acid or water reactions in the wood. Used indoors on untreated, soaped or oiled surfaces. This stain remover contains tannic acid and replaces the oxalic acid that we previously sold at Norrgavel.
