Removing mold should avoid using hard brushes which damage rubber seals. The correct method is to place paper towels on the moldy area, soak them in bleach, and let them sit for several hours before rinsing, allowing chemical components to penetrate and kill bacteria. If mold has penetrated deep layers or is located at high levels that are hard to treat, please consult a professional team.
Avoiding common mold removal myths
Many people have the habit of scrubbing black mold on rubber seals with a hard-bristled brush. In fact, hard brushes destroy the surface of waterproof silicone, causing micro-scratches. Mold spores will inhabit these gaps, leading to more mold growth, ultimately leaving you no choice but to redo the silicone.
When handling moldy materials, you can follow US Environmental Protection Agency's home mold prevention recommendations(opens in a new window)treatment and note the on-site and material restrictions.
Bleach penetration mold removal method
The key to mold removal lies in static penetration rather than violent scrubbing. Please be sure to follow safety guidelines; mixing bleach with acidic cleaning agents (such as toilet bowl cleaner) is strictly prohibited to avoid creating toxic gas.
Before using bleach, please first understand Method for using bleach from the Centre for Health Protection(opens in a new window), and operate according to the product label.
- Ensure the surface is completely dry; mold killing effectiveness is lower when wet
- Roll kitchen paper towels into strips and stick them on the moldy rubber seals or gaps
- Slowly spray or pour bleach of appropriate concentration until the paper towels are completely soaked and adhere tightly to the surface
- Let sit for four to eight hours, waiting for chemical components to penetrate the mold roots
- Remove paper towels, rinse clean with water, and ensure the environment is ventilated until completely dry
