[Solved] How To Remove Limescale From Toilet Below Waterline

So how to remove limescale from toilet below waterline? Limescale is a mineral deposit left behind by hard water. It consists mostly of calcium carbonate.

Limescale accumulation in the toilet bowl leaves your toilet looking ever dirty, no matter how much you clean it. The icky limescale deposit starts out as a brownish stain but over time, it can turn black and more unsightly.

Limescale usually forms below the waterline because that’s the part that is always covered with water. It can also form above the waterline but these deposits are usually easy to clean using normal toilet cleaners.

Best Ways to Remove Limescale from Toilet Bowl

A. Descaler

Any decent store-bought descaler will easily get rid of the limescale in your toilet. You just need to follow the instructions on the label. If your toilet looks particularly bad, you may need to use the limescale remover more than once.

Most store-bought descalers are highly concentrated, so they are effective even on a toilet that looks really bad.

B. Vinegar

If you don’t want to buy a descaler, vinegar is a good alternative. It’s also cheaper and you likely already have a bottle in your kitchen.

The acid in vinegar softens the limescale and dissolves it away.

To use vinegar, first drain the toilet bowl. Turn off water supply to the toilet than look for something to scoop out the water at the bottom of the bowl.

When the bowl is empty, pour a litre of undiluted vinegar into the bowl and let it sit for about three hours. You can also leave it overnight.

Scrub the toilet bowl then flush to rinse it. If there are still some deposits of limescale, pour more vinegar and let it sit for a few more hours.

When the toilet gets clean, reopen the water supply valve.

To keep limescale from forming, pour a litre of vinegar in the toilet bowl every couple of weeks (no need to empty it) and let it sit overnight before scrubbing and flushing. This will get rid of minor limescale deposits before they grow bigger and harder to remove.

C. Sandpaper

Yes, you can buff out limescale using sandpaper. However, we recommend starting with a vinegar treatment to get rid of the worst of the deposit. Then, you can scrub out any remaining limescale with sandpaper to get that brilliant white clean finish.

Remember to put on a pair of gloves before you attack the toilet. Drain the toilet bowl, pour in a litre of vinegar and let it sit for a few hours.

To buff out any remaining limescale, start with a medium-grain sandpaper (make sure the toilet bowl is empty). Then polish the bowl with a fine-grain sandpaper.

Flush the toilet to rinse the bowl.
