Using the pumice stone in the toilet bowl is the second unexpected but effective trick. However, it is necessary to moisten both the stone and the surface to be cleaned to avoid scratches. For efficiency, it is possible to pour two tablespoons of baking soda. This will help you remove dirt deposits more easily. After scrubbing well with the brush, leave on for a few minutes before rinsing. Gently rub the residual stains in a gentle, circular motion with the pumice stone and then flush the flush to rinse.

• Disinfect the toilet bowl with hydrogen peroxide.

Like white vinegar, hydrogen peroxide is effective at killing bacteria and germs. To do this, pour 1/2 cup of this sanitizing product into the toilet bowl. Let the product sit for about 30 minutes and then flush the toilets with clean water. By repeating this operation regularly, you will keep the toilet bowl clean and shiny.
