How well does MoldZymeTM Mold & Mildew Stain Cleaner work on grout?
Tile grout is porous (except for epoxy grout). Mold and mildew, if left alone will penetrate the grout, making it impossible to thoroughly clean. Regular washing with cleaners containing acid or chlorine bleach can cause the grout to deteriorate and can bleach the pigmentation of colored grout. Just one cleaning with acid or bleach-based cleaners can ruin tile and polished stone. If mold and mildew have already penetrated the grout, the best solution is to remove the grout, thoroughly clean the area with MoldZymeTM, and replace the grout. Then use MoldZymeTM as the regular cleaner to keep the grout durable and free from mold and mildew stain. Before replacing grout or tile, it is prudent that the area be cleaned with MoldZymeTM so that the new grout is not being put on top of existing mold and mildew stain that other cleaners may leave behind.
