Even if the toilet looks perfectly clean, inside the flush tank an unpleasant deposit appears over time. Because of hard water lime deposits gradually form on the walls and parts, and sometimes rust and slime appear. All this not only spoils the appearance, but can also over time worsen the work of the mechanism.

A simple remedy that really helps

For cleaning the tank it is not necessary to buy expensive household chemicals. Ordinary citric acid copes excellently with this task.

What needs to be done:

• Shut off the water supply to the tank.
• Flush the water.
• Pour 100–150 g of citric acid right inside the tank.
• Add about a liter of hot (not boiling) water so that the acid dissolves faster.
• Leave the remedy to act for 2–3 hours, and with strong deposit — overnight.

After this it is enough to go over the walls of the tank with a soft sponge or brush. The greater part of the lime deposit will come off easily without strong rubbing.

If the contaminations are old

Sometimes the layer of lime forms over years. In such a case the procedure can be repeated once more in a few days. It is not worth using metal brushes or sharp objects — with them it is easy to damage plastic parts and seals.

How not to allow the appearance of deposit again

So that the tank remains clean longer:

• carry out such cleaning once every 2–3 months;
• if the water is very hard, do prevention a little more often;
• periodically open the tank lid and check the condition of the internal parts.

A few minutes of care once a season will help avoid a thick layer of lime deposit and prolong the service life of the flush mechanism. Such a simple method saves both strength and time, and the result is noticeable already after the first cleaning.
