And this often happens with scaled bathrooms. The problem is that these caked-on tartar stains are (very) difficult to remove without expensive chemicals!

Luckily today I’ll reveal the natural trick I used to effortlessly eliminate those black marks on the bottom of the toilet. The powerful and natural trick is to use citric acid. I wait :

What you need

– citric acid

Result

That’s it, your toilets are now sparkling clean naturally. Easy, fast and efficient, right? No more black, brown or yellow stains on the bottom of the toilet!

Now you know how to remove a black mark from the bottom of the toilet, it’s even cleaner so receiving guests at home!

Also, you didn’t use any chemicals to whiten and descale the bowl. Citric acid is 100% of natural origin, as it comes from corn and beets.

It does not pollute rivers and is compatible with septic tanks. It is therefore an excellent alternative for cleaning an enlarged toilet with a septic tank.

Why does it work? Citric acid is a powerful natural descaling agent that naturally fights limescale.

It is very effective in removing scale in the toilet. It works deeply and the more time you give it to act, the better it works!

Hence the interest in leaving the citric acid to act overnight. This trick works for all types of toilets: wall-hung or floor-standing.

But also for all types of materials: porcelain, enamelled ceramic or stainless steel.

bonus tips

To descale very calcified toilets you can also count on soda crystals (Saint Marc or any other brand)… or Coca-Cola!

Surprising, but it works! The use of bicarbonate should be reserved for regular maintenance of toilets.

But used alone, it’s not powerful enough to clean heavily soiled bathrooms.
