Help - Cat urine smell on fireplace brick
We recently bought a house with a lot of cat urine damage. After sealing the subflooring, re-painting the whole house ceiling to floor, replacing floor coverings & interior doors,and removing sliding bedroom closet doors, we could still smell cat urine. We determined that it's coming from the brick on the fireplace. We are considering covering the brick with tile, but if we could get the smell out we'd like to keep the brick.
