How to Clean a Calcium Urinal Block
Urinals are special toilets designed for men. (urinal image by sk_design from

Urinals are a form of toilet specifically made for men. They are smaller than regular toilets and are attached to the wall instead of the floor. Calcium blocks are caused by hard water in your water system. These blocks can be easily removed as you clean the urinal itself, and it does not take a long time to do. If you do have hard water running through your plumbing system, install a hard-water filter in order to avoid the calcium build-up again.

  1. 1

    Put on the latex or rubber gloves to protect your hands from germs and bacteria.

  2. 2

    Pour 1 cup of baking soda in each urinal with a calcium blockage followed immediately by 2 cups of white distilled vinegar. Allow 15 to 30 minutes for the solution to work.

  3. 3

    Rinse the drain with 4 to 6 cups of extremely hot water. This will flush out the blockages and help to clean the drain system.

  4. 4

    Wipe down the urinal with sanitiser if required and follow up with a clean damp cloth. Allow to air dry.

Tips and warnings

  • Use an industrial strength multipurpose cleaner for a cleaner surface. An example of an industrial cleaner is 409.
  • Do not ingest any chemical cleaner or get them into your eyes. To do so will cause serious irritations, health problems and possibly chemical burns.
