If the water in the sink starts to stagnate, you shouldn't immediately call a plumber and pay him money. A blockage is a common thing, but you shouldn't delay cleaning it.
Of course, before calling a plumber, you can try to buy some special cleaning products that are sold in any hardware store. But you will have to spend money on them too.
It's high time to use one simple but effective "folk" method.
Even the most stubborn blockage can be eliminated with just a couple of steps.
To do this, you will need 100 mg of baking soda and acetic acid.
There is nothing complicated in what follows, the main thing is to prepare these ingredients.
It should be remembered that these substances are irritants that can be dangerous to human skin.
First, take baking soda. It needs to be poured into the drain. The soda should get as deep inside as possible.
Then you can start to carefully pour vinegar into the drain. It is worth remembering that when baking soda and vinegar interact, a reaction will occur, accompanied by the release of carbon dioxide.
It is necessary to wait 3-4 minutes for the substances to interact with each other.
After this, you need to turn on the water and evaluate your work. If you do everything correctly, you won't have to repeat the manipulation for a long time.
Usually, carbon dioxide will clear the blockage the first time. During the reaction, bubbles and foam should be inside the drain, not outside.
This will indicate that all the gas is inside the drain.
