Minerals are naturally found in the water in your home. These minerals, such as calcium and silica, can build up in your toilet and on your glass shower door, creating a film that is difficult to remove. Silica is one of the materials found in sand and quartz. Removing silica from your toilet and glass shower doors is a difficult process, but it is not impossible. If the first method you try does not remove the silica build-up, simply move on to another method.

Scrub the toilet bowl with the scrubber vigorously to remove the loosened silica build-up. Flush the toilet to rinse it clean.
Apply a hard mineral chemical remover to a sponge. Scrub the glass shower door with the sponge. Add more hard mineral chemical remover if necessary and continue scrubbing until the silica build-up is removed. Rinse the shower door with cool water.

Allow the vinegar to sit on the shower doors for 5 to 10 minutes. Scrub the doors clean with a cloth and rinse with cool water.
