Black mold around baths and showers is a common issue that can be both unsightly and harmful to health. Over time, the moisture in these areas provides the perfect breeding ground for mold, particularly on silicone sealants.
1. Preparation is Key
Before you jump into removing the mold, preparation is essential to ensure that the mold is thoroughly eliminated and doesn’t return.
Ventilation
Mold spores and bleach fumes can be harmful, so open any windows or doors and, if possible, use an extractor fan.
Gather Your Supplies: You'll need a few essentials to tackle mold effectively:
Bleach or a mold-specific cleaner
A spray bottle
Rubber gloves
An old toothbrush or soft scrubbing brush
Paper towels or a clean cloth
Protective Gear
Since you’ll be using bleach, it’s a good idea to wear gloves, protective goggles, and, if possible, a face mask to avoid breathing in fumes.
2. Applying the Bleach Solution
Using bleach is one of the most effective ways to kill mold on silicone sealant.
Create the Bleach Solution
Dilute bleach with water in a spray bottle (about 1 part bleach to 3 parts water is effective). Alternatively, you can use a store-bought mold remover if you prefer.
Spray the Moldy Areas
Generously spray the bleach solution onto the affected areas, ensuring that the mold is well-soaked.
Let It Sit
For the best results, leave the bleach solution on the moldy silicone for at least 15-20 minutes. This gives the bleach enough time to penetrate and kill the mold.
Tip: If the mold is particularly stubborn, you can apply bleach-soaked paper towels or cotton wool balls directly to the silicone and let them sit for a few hours before scrubbing.
3. Scrub Away the Mold
After letting the bleach sit, use an old toothbrush or scrubbing brush to gently scrub the moldy areas. Focus on the spots where the mold is darkest, but be careful not to scrub too hard, as this can damage the silicone.
Rinse the area with clean water to wash away any remaining bleach and loosened mold.
Important: Make sure to dry the area thoroughly after rinsing. Moisture is a primary cause of mold, so keeping the area dry is key to preventing its return.
4. Reapply High-Quality Silicone if Needed
If the mold has deeply penetrated or stained the silicone beyond cleaning, it may be time to remove and reapply fresh silicone. This step can prevent mold from quickly reappearing and ensure a longer-lasting solution.
Remove Old Silicone
Use a utility knife or silicone remover to carefully cut away the old, moldy silicone. Be gentle to avoid scratching the bath or shower surfaces.
Clean and Dry the Area
Before applying new silicone, clean and dry the area thoroughly. Any remaining moisture can lead to mold forming under the new silicone.
Apply High-Quality Silicone
Use a mold-resistant, bathroom-grade silicone sealant. Applying high-quality silicone reduces the chances of mold returning, as these products are designed to withstand damp, mold-prone environments.
Allow Proper Curing Time
Once applied, let the silicone cure completely before using the bath or shower, as exposure to water can weaken the bond and create gaps that trap moisture.
5. Prevent Future Mold Growth
Once you’ve successfully removed the mold and refreshed the silicone, a few preventive measures can help keep mold from returning.
Ventilation and Humidity Control
Keep your bathroom well-ventilated by using an extractor fan or opening windows, especially after showers.
Regular Cleaning
Clean the silicone and surrounding areas regularly with a mild cleaning solution to prevent mold from gaining a foothold.
Wipe Down Surfaces
After each shower or bath, wipe down the silicone and other surfaces to reduce lingering moisture.
By following these steps, you can remove black mold from your bathroom silicone and ensure it stays mold-free for longer. Remember, using high-quality silicone and keeping moisture levels down are key to preventing mold. With a little upkeep, your bathroom can remain a fresh and healthy space.
