  • High-Visibility Vest: For work in high-traffic areas, wear a high-visibility vest to enhance your visibility to others.

Step 3: Choose a disposal method

The best disposal method will depend on the type of liquid and the level of contamination:

  • Small quantities of moldy liquid in containers: If it’s a small amount of moldy liquid, you can pour it down the drain or toilet. Make sure to run plenty of water afterward to flush the drain and prevent any mold spores from lingering in the pipes.
  • Large quantities of highly contaminated liquid: For larger quantities or if the liquid is heavily contaminated with mold, it’s safer to dispose of it in sealed garbage bags. Double-bag the liquid to prevent leaks and place it in an outdoor trash bin.
  • Toxic or hazardous moldy liquid: If the liquid contains hazardous substances or chemicals, do not pour it down the drain or throw it in the regular trash. Contact your local hazardous waste disposal facility or municipality for proper instructions on safely disposing of it.

Step 4: Reduce moisture

Mold thrives in moist environments, so fix any water leaks or sources of moisture before proceeding with the cleanup.

Step 5: Dry the area

Use fans and dehumidifiers to thoroughly dry out the affected area. Mold cannot grow without moisture.

Step 6: Remove moldy materials

For non-porous materials like glass or metal, clean with a mixture of detergent and water. For porous materials like drywall or fabric, it’s often best to discard them as it’s challenging to completely remove mold from these materials.

Step 7: Clean and disinfect the area

If the moldy liquid has spilled on a surface, clean and disinfect the area using appropriate cleaning products. Wipe the area thoroughly with a disinfectant to ensure any remaining mold spores are killed.

Step 8: Dispose of contaminated materials

If any materials (such as rags or cloths) used to clean up the moldy liquid are heavily contaminated, dispose of them in sealed garbage bags as well.

Step 9: Prevent future mold growth

Step 10: Wash your hands

After handling moldy liquid and cleaning the affected area, wash your hands thoroughly with soap and water to avoid any potential contamination.

Use Disinfectants for Mold Removal

Mold is a living organism, so the primary focus of cleanup should be on effectively killing the mold to prevent its reproduction. Disinfectants such as bleach or biocides can be highly effective if used properly and for an adequate duration.

Here are some common mold removal products and their application methods:


While bleach can be toxic to mold, it should only be used in diluted form and applied to non-porous surfaces like wood or tile. It may not penetrate deeply into materials. Leave the bleach on the surface for at least 15 minutes to ensure it kills the mold.



Safe to use in a solution, Borax kills mold and helps prevent further growth. It does not require rinsing.



Spray vinegar on the moldy surface and let it sit for about an hour before wiping it down. Repeat the process to continuously prevent mold regrowth.



Similar to bleach, ammonia is effective on non-porous surfaces. After application, the mold can be wiped away.


Hydrogen Peroxide

Hydrogen peroxide works similarly to vinegar. Spray it on the surface and leave it for some time before scrubbing it off.
