If you have a cast iron or ceramic sink, they require appropriate care.
If the operating rules are violated, the condition of the plumbing may worsen.
In order for the plumbing to look attractive for many years, you need to follow certain rules. Stains, for example, need to be removed immediately, otherwise it will be almost impossible to get rid of them.
Therefore, it is better to wash plumbing after each use.
For more thorough cleaning, soda is recommended. First, we wash the surface with a damp sponge, then spread a layer of soda and start cleaning.
Then rinse off the cleaning agent and wipe the surface dry.
Such plumbing is even more demanding in terms of care. In order not to harm the coating, it is necessary to use gentle means.
However, you can try to get by with folk remedies.
To do this, dissolve a couple of spoons of soda in water, treat the sponge and start cleaning. With this approach, the sink will always look decent.
