If your white bathtub has become yellow over time, as if it has a dirty and sticky coating on it, then you need to know this method. It is tested in practice, so it works 100%, both with cast iron and acrylic surfaces.
Details
Yellow stains on the bottom of the bathtub, which are difficult to wash off with just a shower, appear when someone is too lazy to regularly rinse the bathtub after bathing. Objectively, this situation happens in every second home, so if you have encountered such a phenomenon, do not think that you are alone.
You can wash the bathtub quickly, without exerting effort and without standing “on cancer”. Not every back is ready for such loads. To do this, you need to fill the bathtub with water overnight, preferably hot. You need enough water to cover the level of yellow plaque.
Dilute 2 packs of citric acid in water and go to bed. In the morning, you just need to drain the water and rinse. No friction, because the acid will eat away the yellowness and the bath will be white again, like new.
