Bleach vs Vinegar vs Commercial Mold Cleaner

Quick Answer

For small areas on hard, non-porous surfaces, physical cleaning with detergent and water is the baseline. EPA does not recommend routinely using bleach or another biocide for mold cleanup. A disinfectant may be appropriate for a defined sanitation need, such as certain contaminated-water events, when the product label supports the surface and use.

If mold is extensive or on porous materials, follow our guide on cleaning vs removal.

Bleach may disinfect compatible hard, non-porous surfaces after debris has been physically cleaned away, but it is not a routine mold-removal step. It does not make moldy drywall, insulation, carpet padding, or other porous materials safe to keep. It can create hazardous fumes and should never be mixed with ammonia, acids, or other cleaners.

• Use only for a defined need on a label-approved surface
• Do not use it to salvage moldy porous materials
• Follow label ventilation, dilution, contact-time, and PPE directions

Commercial mold cleaners are designed for specific surfaces and may include detergents, stain removers, or antimicrobial agents. Look for products intended for the material you are cleaning and follow label directions. Do not use a chemical as a substitute for cleaning, drying, or removing contaminated porous materials.

• Choose products for the surface type
• Follow dwell time and rinse instructions
• Follow label PPE and ventilation requirements

• Fix the moisture source and confirm the work area is safe
• Use gloves and eye protection, particle protection appropriate to the work, and all chemical PPE required by the product label
• Isolate the area so particles do not spread to other rooms
• Remove moldy porous materials and seal them before carrying them out
• Damp-clean hard surfaces with detergent or a suitable product
• Rinse if the product label requires it, then dry completely
• After the area is dry, use a sealed true-HEPA vacuum for final settled-dust cleanup
