Every responsible homemaker is well aware of the importance of regular and meticulous maintenance when it comes to plumbing. This not only helps preserve the aesthetic appeal of the fixtures but also extends their lifespan.
Among all the plumbing fixtures, the toilet bowl requires special attention. It is crucial to clean not only the bowl itself but also the toilet tank. Over time, both the inner surface and the components of the flushing mechanism accumulate residue and rust, which, if left unattended, can cause the toilet to malfunction.
Reasons for the formation of scale and rust in the toilet cistern
The water we utilize is frequently tainted with various impurities. While it undergoes various purification processes, a few of these impurities, such as limestone, still persist. When these impurities enter the toilet bowl, they settle on the walls and the flushing mechanism.

Initially, a thin layer of limestone covers the entire surface. However, if not promptly removed, it gradually turns into stubborn deposits. Eliminating solid deposits is much more challenging than removing a thin layer of limestone. Moreover, aging water pipes contribute to the presence of rust, which accumulates on the inner surface of the tank and becomes denser and thicker over time.
According to the reference, the hardness of the water determines the rate at which a layer of limestone and rust forms in the drain tank.
Minute particles of rust settle on all internal components of the tank, including the drain mechanism. This disrupts its normal operation, and if the scale is not eliminated, the mechanism will eventually fail. Consequently, water will start to leak from the tank, creating an environment for the growth of pathogenic bacteria, mold, and an unpleasant odor.
How to remove rust and yellow scale at home
You have the ability to eliminate lime scale and rust by yourself. This can be achieved by using store-bought cleaning agents or by utilizing traditional methods.
Did you know? Traditional methods can sometimes yield even more powerful results than commercially available products.

When selecting a cleaning agent, it is important to remember that optimal outcomes are only attainable. Accordingly, the product should be chosen based on the tank’s material. For instance, acidic substances should be employed for cleaning ceramic tanks, whereas gentler alkaline solutions are suitable for metal tanks.
Assistance required! Prior to commencing the tank cleaning process, it is essential to gather gloves and turn off the water supply.
Using store-bought products
If there is a thin layer of lime scale and rust on the inner surface of the tank and the drain mechanism, it is possible to address them without the need for concentrated cleaning agents. For cleaning the tank, you may consider using products such as "Pemoxol", "Cinderella", "Pemos" or "Myth".
In the event of a stronger buildup, more powerful solutions will be required: "Sanox" and "Biocide-C" are capable of removing any type of contaminants in just a few minutes.
Furthermore, there are also gel-based cleaners available on the market, which have gained significant popularity among users.

- There are various types of "Cilit" specifically designed to target different types of contaminants, such as rust or lime scale. Moreover, this product can effectively eliminate tough stains and restore the shine of sanitary ware.
- "Domestos" is a thick and viscous substance that is ideal for removing dirt and disinfecting sanitary ware.
- Comet is a highly effective cleaner that can tackle all types of contaminants. However, it is important to remove plastic parts before using this product, as it can have a negative impact on them.
- "Toilet duck" is an affordable option that can effectively clean and refresh sanitary ware.
- Sanita is capable of removing even stubborn rust deposits.
- "Sanfor" is an excellent cleaner that not only removes contaminants, but also eliminates fungus and mold. It can be used to clean all types of plumbing fixtures and tiles.
Please take note! It is crucial to adhere to the specified duration on the packaging and allow the cleaning solution to remain on the surface of the bathroom fixtures.
Folk methods
There are several methods that can be used for tank cleaning:
- One option is to use vinegar. To do this, mix a small amount of table vinegar with water and pour the mixture into the tank. Let it sit for a few hours and then drain the solution. Finally, use a stiff sponge to thoroughly wipe the inside of the tank.
- Another method involves using toothpaste. Simply make several holes in a tube of toothpaste and place it inside the tank. Each time you drain the water, the self-cleaning process will occur.
- A third option is to use citric acid. You will need 5-10 sachets of acid for this method. Pour the contents of the sachets into a container and add room temperature water. Stir the solution until all the acid crystals are completely dissolved. Let it sit for 3-4 hours and then use a stiff sponge or brush to rub the walls of the tank.
- To remove the build-up of plaque and rust, the process is relatively straightforward. However, to save time on extensive cleaning, it is essential to periodically cleanse the interior of the tank. This way, it is possible to eliminate fresh deposits using just a damp cloth, avoiding the need for potent chemicals.
