If the silicone sealant in your kitchen and bathroom is mouldy, you’re not alone. This rubbery strip is designed to prevent water from seeping into gaps between tiles, floors and shower trays, but this is a double-edged sword. After all, it’s this exposure to moisture that makes it a breeding ground for mould.
Kitchens and bathrooms are also the dampest (and sometimes smallest) rooms in the house, and sealant is typically located in tiny corners and crevices. And when airflow is limited and there’s no respite from moisture and humidity, mouldy silicone gets worse and worse as the weeks go by. This makes it harder to remove in the long run.
