What causes toilet bowl stains?

Before we jump right into how to remove stubborn stains from toilet bowls, let’s explore the four common toilet bowl stains and the reasons behind their existence.

1. Limescale

Limescale is common stains you will find inside your toilet bowl. These stains are caused by high concentrations of particular minerals in the water supply, such as calcium.

As the water evaporates, the mineral deposits are left behind in the toilet bowl, gradually accumulating and forming chalky white, or yellow stains.

2. Rust stains

Rust is another common stain found in the toilet bowl, sinks, and tubs. The high iron content present in the water reacts with the water and oxygen to form iron oxide (reddish-brown stains) on the porcelain material that are hard to remove and simply don’t wash away.

3. Copper stains

As the water flows through the copper supply pipes, small amounts of the metal are dissolved, mostly due to corrosion, resulting in blue-green or bluish stains accumulations on surfaces such as toilet bowls, sinks, and bathtubs.

4. Mold stains

Mold spores, when coming into contact with moisture, water leaks, or humid conditions, grow and multiply in your toilet around the waterline as well as under the inner lip of the bowl, leading to black and dark green stains with a musky and unpleasant odor.

Follow these steps to remove stubborn stains from the toilet bowl effectively:

Step 1: Turn off the water supply

Pour Lysol® Toilet Bowl Cleaner - Power into the toilet bowl. Direct the nozzle under the rim and squeeze the bottle gently to distribute the solution smoothly around the entire surface. The angled bottle helps target the hard-to-reach areas to ensure maximum bowl coverage.

Allow the cleaner to sit in the bowl for 5-10 minutes, giving the solution ample time to penetrate and dissolve dirt, grime, germs, stains, and other mineral deposits.

Step 4: Scrub with a toilet brush

Scrub the insides of the toilet bowl using a toilet brush. Remember to scrub the areas with more stains diligently.

Start cleaning from under the rim of the toilet seat and work your way down to the main hole of the toilet bowl and around the edges of the bowl.

Step 5: Turn on the water supply and flush

Turn on the water supply and wait for the water to fill up the toilet tank completely. Flush the toilet bowl to thoroughly rinse away the cleaning solution and the accumulated mineral deposits. Repeat the flushing process until all the cleaning solution has been washed away.
