Whenever it’s related to cleaning toilets, chlorine bleach is always a good bet. The odor of chlorine bleach may be so strong that it makes using it uncomfortable. However, it is a fantastic cleaning product that has never let us down. We’ve used Chlorine Bleach before and found it to be really effective.


  1. Rinse the entire toilet with water so that Harpic doesn’t contact the bleach. If it does, the mixture will create a chemical compound that is essentially toxic gas. 
  1. Mix the bleach with some water. The water and bleach mixture should be 1:1 to create a perfect balance. Use water-based on the intensity of the discoloration.
  1. Now, pour it on the stain. Pour bleach on a towel and press it against the stain if it is on the side edge.
  1. Wait a few minutes for the bleach to rest on the area. Then, using a fresh towel, wash away the bleach.

To finish the cleaning process, wash the area with soap and warm water. Chlorine bleach has been used to disinfect a variety of environmental surfaces for millennia. As a consequence, it is effective in extracting such harpic stains.

Added Tip: Put down a tarp to prevent the chlorine solution against leaking on the floor. This is required since the chlorine bleach has the potential to irreversibly damage the floor.
