Community Tips
Apply mold remover only to dry grout, as moisture dilutes the active ingredients and reduces effectiveness by up to 50%. Allow the bathroom to air dry completely or use a fan for 30 minutes before spraying products like Tilex Mold & Mildew Remover ($4-6) to maximize penetration into porous grout lines.
Never mix mold removers with bleach or ammonia-based cleaners, as this chemical combination produces toxic chlorine gas that can cause respiratory damage even in well-ventilated bathrooms. Always read product labels and use only one cleaning agent per application cycle.
Sealing grout after cleaning prevents mold regrowth for 1-3 years and costs significantly less than repeated deep cleanings; a single application of Aqua Mix Sealer's Choice Gold ($15-22) covers 100-150 linear feet and eliminates the need for monthly treatments on problem areas. ---
