How to remove limescale from toilet below the waterline (Step By Step)

Before Cleaning the toilet

Yeah, it’s grim, safe to say we have found a good test subject here for the Harpic power plus. Let’s get some down there and see what effect it has on our brown limescale stains. This highly rated cleaning product has been specially formulated to be an effective limescale remover. So let’s chuck it down the toilet bowl and see what effect it has on our limescale deposits.

So we have poured it in. It’s quite thick and I don’t know why but I wasn’t expecting it to be blue.

So we let the power plus sit for a while before attacking the toilet with a toilet brush. We have then decided to let the formula sit again for a while before we flush it away and reveal the result.

The limescale mineral deposits are really tough to remove, so leaving the limescale remover in the toilet bowl between scrubs is a great way to improve its effectiveness.

It’s definitely done a job. I think we would be expecting miracles for it to have completely cleaned the limescale deposits from this toilet on the first attempt. This method is brilliant because it doesn’t involve tons of elbow grease to clean the limescale off your toilet bowl.

We chucked the remainder of the bottle down the toilet and decided to leave it for the rest of the day to see if that would finish the job off. These limescale stains were tough, but this toilet cleaner is really doing well removing these calcium deposits.

After Second Clean

Really good result, the toilet is almost there. Just a tiny bit more to come off. We think with a good scrub with the toilet brush this job will be done!

The sad thing though is that your limescale will probably be back, which is why the 6 pack of cleaner makes sense so you always have some on hand.

This is because excessive limescale build-up like in the photos above is usually caused by damage to your enamel. So once your enamel has been damaged it will keep happening.

FAQ’s

What is limescale in toilets?

Limescale is a hard chalky deposit, consisting mainly of calcium carbonate (CaCO3). It can go brown due to iron content in your water, this is what commonly happens in toilets and is why it looks a horrible browny colour.

Hardwater causes limescale build-up. Hardwater just means water that is full of minerals including calcium and magnesium carbonates, bicarbonates and sulfates. Hard water is formed when water seeps through deposits of limestone and chalk.

Why do you get limescale in a toilet?

Beyond living in a hard water area there are other reasons why you may suffer from limescale build-up in your toilet whereas next door may not. The enamel layer on your toilet normally protects against limescale build-up. It only begins to build once the enamel layer has been damaged.

Bleach can damage enamel and strip it from your toilet, this will then allow limescale to start to form. Other abrasive cleaners can also be really bad for the enamel.

Because the limescale is formed by the water in your toilet it normally appears under the waterline. That is why products have to be designed to remove limescale from toilets specifically below the waterline.
