The first remedy consists of using 2 tablespoons of white vinegar and 3 tablespoons of baking soda. Stir them together, wait for the effervescent chemical reaction to wear off, soak a soft sponge in the solution, and rub it into the cup. Let it sit for a few minutes and then flush.

To get rid of the black caked on the bottom of the well, you can make a mixture of:

100g of bicarbonate,
30 ml of ossigenata water,
juice of 1 lemon,
water as much as is enough.

Place all the ingredients in a bowl, stir vigorously, and then use this solution to clean the toilet, but don’t flush the water right away! Leave it on for twenty minutes.

If lime is the problem, to dissolve scale, get:

200 grams of baking soda,
200 grams of coarse salt
300 ml of vinegar.

First, put the salt in the toilet bowl. Then add the baking soda and let it sit overnight. The next day, in a saucepan or in the microwave, heat the vinegar and pour it down the toilet. You will notice the formation of a particularly effervescent foam. Wait for the reaction to finish and then admire your masterpiece!

And without effort, without rubbing for a long time, without using chemicals and without contaminating!
