Citric acid
Citric acid is also very useful for this purpose. Here too, it is an excellent product for many reasons. As for the yellow sanitary strips, it is enough to dissolve approximately 150-200 g of the product in about a litre of water and mix. You should achieve a uniform solution.
In this case too, we must pour everything into a spray bottle or vaporizer. At this point, we spray most of the liquid obtained on the yellow stripes of our toilet. It is necessary to let the mixture act for at least a couple of hours . However, the final result will be really excellent!
salt and lemon
Another particularly useful remedy against yellow streaks in the toilet bowl is salt combined with lemon. These are products that have an exceptional degreasing power, especially when combined together.
They can also be very useful against limestone. If you want to try this technique, you just have to sprinkle fine salt on the affected parts and then cover everything with lemon juice. Leave it on until everything has dried and then proceed to rub vigorously. The end result will be crazy.
