Silicone is used to form a waterproof bond in construction and repair of glass aquariums. Once cured it becomes a permanent, solid seal that will last for the life of the aquarium. One problem that arises when using silicone is that, if it is smeared onto the glass and allowed to dry and cure, it leaves a cloudy mark that is unsightly. It’s not too complicated to remove silicone from an aquarium and restore the glass to optimise the clarity it was designed for.

Skill level:

Things you need

  • Razor glass scraper
  • Soft bristled brush

  1. 1

    Hold the glass scraper at a 45-degree angle and push it against the silicone smear in a scraping motion, taking care not to gouge the silicone bead that holds the glass panels together in the corners of the aquarium. Repeat this process on each section of silicone until all smears have been lifted.

  2. 2

    Dust the crumbs of silicone off or out of the aquarium, using a soft bristled brush.

  3. 3

    Clean the glass where the silicone residue has been removed, using a household glass cleaner and paper towels.

Tips and warnings

  • Always wash the inside of the aquarium according to a standard fish care guide before set up.
