we have a deck situated in Montral, Quebec. there are mushroom spores growing out of the ends and sides of the 6 x 6 hemlock beams and posts. wondering if there is a way to treat it. tried bleach but it did not do the trick… before replacing, we are looking at possible options to save it. Treatment options? Ozone, Aran, chemical… open to review options, but would like to keep the environment as part for the solution.Todd
