Introduction

That embarrassing brown stain in your toilet is enough to make you recoil in horror. However, if you live in a hard water area, this is most likely the problem. The last thing that you want is for your toilet to look like it has not been cleaned for months.

What Causes Limescale in the Toilet?

In many areas there is a high amount of dissolved calcium and magnesium in water, which we refer to as hardwater. It gradually accumulates over your lovely white toilet bowl in the form of brown chalky deposits. Because of this, it's essential to regularly clean the toilet bowl thoroughly.

In this article, you will learn how to remove stubborn limescale from the toilet and toilet rim in only 15 minutes.

Step-By-Step Instructions

Step-by-step instructions on how to remove hard water stains from your toilet bowl with one main ingredient.

Important!
Make sure the room is well ventilated and ALWAYS use eye protection when using acid.
Step One:
Start by emptying the water out of the toilet bowl.

  1. Turn off the water supply to your toilet and flush.
  2. Remove the remaining water at the bottom of the bowl with a wet-dry vacuum or scoop it out with a cup.

Step Two:
Pour the brick acid into the bowl. Enough acid should be added to reach the normal water level.

Step Three:
Note:Only follow this step if you have a stain along your toilet's rim.

Get your toilet paper and soak it in the acid. Then compress it into the rim so that there is contact between the rust stain and the acid.

Step Four:
Let the acid do its job and leave it to soak for 15 minutes.

Step Five:
Using a toilet brush, scrub the toilet bowl for about 30 seconds. Make sure that you use the brush gently to avoid splashing acid on yourself.

Step Six:
Switch the water back on. To remove the acid and dirt, flush the toilet while the brush is inside (cleans the brush too).
