Can Black Mould be Removed from Silicone?

Although most silicone sealants are rather resistant to mold growth, after their prolonged exposure to the high moisture in damp areas, you will eventually end up having to clean black mold growth on older silicone seals. A good way is to soak some cotton wool in household bleach, place it on the affected area and let it sit for at least three hours. When the wool is removed, wash it off with water.
