Use salt in the bathroom this way and see what happens: Problem solved

Pouring salt into the bath can eliminate the presence of yellow stains that settle at the bottom of the cup over time. Salt is also a powerful disinfectant. How long does it take? Even 100 grams is enough.

You need coarse salt left on the walls of the toilet. Distribute it in a balanced way, trying to cover each part as much as possible, then let it act for at least a few hours, or even overnight. Once the necessary time has passed, all that remains is to pull the plug and let the water flow to rinse everything.

This method is perfect for once a week and allows you to clean bathroom surfaces, brighten them and disinfect everything well. For a practical, inexpensive and easy to implement method.
