I Can't Remove Algae From Silicone

Algae and mould growth is a common problem in the bathroom. Silicone sealant around the bath and shower fixings is particularly susceptible to bacterial growth. Algae and mould require warm, damp conditions to grow and the bathroom provides an ideal climate. The silicone sealant will rot if the algae and mould growth is left untreated, which may cause water damage to the bathroom floor and walls. You can produce an inexpensive cleaning solution using household items to remove the algae.

  1. 1

    Mix 1/2 cup of white distilled vinegar to 1/2 cup of water and pour into an empty, clean spray bottle. The vinegar is a natural, acidic cleaner.

  2. 2

    Spray the mixture on the algae on the silicone sealant and leave for 10 minutes to allow the vinegar solution to soak into the bacteria.

  3. 3

    Mix 1/2 cup of baking soda with enough water to form a thick paste.

  4. 4

    Dip the scrubbing brush into the baking soda paste and apply the paste to the algae on the silicone sealant.

  5. 5

    Scrub the silicone until the algae is completely removed.

  6. 6

    Wipe the silicone with a dry towel or absorbent cloth.

Tips and warnings

  • Keep the bathroom vented when taking a shower or bath. Algae growth is restricted in ventilated areas.
  • Do not scrub the silicone sealant if it's loose. The silicone must be replaced if it peels away from the bathroom fixtures.
