1. Replace the silicone: If your toilet silicone has been used for some time and it is difficult to clean, then the best way may be to replace the silicone. You can buy new silicone, thoroughly clean the toilet joint with alcohol or detergent, and then reseal it with new silicone.
2. Cleaning silica gel: If you don't want to replace silica gel, you can clean it with some cleaning agents. You can choose ordinary disinfectant, bleaching powder, vinegar or alkaline cleaner to clean. Before using the cleaner, clean the toilet, then dilute the cleaner with water, then gently brush the surface of silica gel with a brush, and finally wipe it clean with water.
3. Use deodorant: If the smell is bad, you can use some special deodorant to remove it. You can choose some deodorant containing activated carbon, plant essential oil or oxidant, which can be sprayed on the surface of silica gel or placed beside it. These deodorants can adsorb odor molecules and reduce the intensity of odor.
In a word, keeping a clean and dry environment is the best way to prevent the odor of toilet silicone. Cleaning silica gel regularly, using deodorant or replacing silica gel can effectively remove odor.
