"Domestos" and other products will cost several times more than this penny trick from cunning housewives.
Over time, the toilet becomes covered with a layer of limescale, and rusty stains and other contaminants can be seen in places, which greatly cheapen even expensive plumbing fixtures.
Usually, housewives maintain the cleanliness of the toilet with the help of purchased "chemistry". But even experts in the field of cleaning services claim that it is possible to achieve order in the bathroom without special means.
For example, regular vinegar copes with limescale deposits no worse than advertised branded “chemicals”.
All you need is paper napkins or toilet paper. The material is soaked in vinegar and then “glued” to the inner surface of the plumbing. By the way, this method also works with a bathtub.
The only downside to this method is that it needs to be left for 8-10 hours. Therefore, it is better to use this method in the evening. Citric acid, which together with vinegar will help get rid of yellowing of plumbing, will help enhance the effect.
