Why Does Bathroom Silicone Go Mouldy?
Mould develops on bathroom silicone when moisture remains on the surface for a long time and cleaning residue builds up around the edges. Shower enclosures, baths, basins and tile joints are vulnerable because they are frequently in contact with water. The first black spots may look small, but they gradually spread along the joint, cause odours and spoil its clean appearance. Dirt is only part of the problem: airflow, drying habits, product choice and ageing material all play a role. Understanding the causes makes it easier to reduce staining and delay its return. A simple home maintenance routine keeps the bathroom fresher and helps the silicone joint last longer.
