Will Concrobium Mold Control discolor the treated surface?
No, Concrobium Mold Control will not discolor hard or fabric surfaces, as there are no bleaching agents in the product. As with any cleaning solution, it’s always a good idea to test Concrobium Mold Control on an inconspicuous section first. NOTE: In our years of experience we’ve encountered just two surfaces that can have negative reactions to Concrobium Mold Control: suede and billiard balls.
