Hey Guys: I've searched the forum for different thoughts on removing pee stains from wood (hidey houses, shelves, etc..) So far I've tried equal parts Hydrogen Peroxide/Water, Vinegar/ Water, and Hydrogen Peroxide/Vinegar. I let the solution sit on the stain for 10ish minutes, scrub with a sponge, rinse with water, and dry. I have no doubt that everything is sanitary but the stains are still there. Am I doing something wrong? Any more suggestions?
