Moldex Mold & Mildew Stain Remover

While the bleach gel formula is designed to penetrate deep, you will typically need to lightly scrub or wipe the area after letting it sit to fully remove stubborn mold and mildew stains. It is not a 'spray-and-walk-away' product.

Because this formula contains bleach, it can discolor certain materials. Avoid using it on colored grout, natural stone, or delicate surfaces unless you have spot-tested an inconspicuous area first to ensure it won't cause fading.

While it lacks added perfumes, the product contains bleach, which has a distinct, sharp odor. We recommend keeping the area well-ventilated by running a fan or opening a window during and after application.

Yes, the gel consistency is specifically formulated to cling to vertical surfaces. This allows the bleach to stay in contact with the mold longer than a thin, watery spray would, making it effective for shower walls and tile.

Yes, the biodegradable nature of the formula makes it generally safer for septic systems when used as directed. However, as with any bleach-based product, avoid using excessive amounts to maintain the balance of your system.
