The appearance of characteristic yellow streaks on the toilet is not uncommon.
This is usually due to poor water quality.
Sometimes you also have yourself to blame: the streaks appear even if you don't regularly wash your plumbing. However, you can remove them.
What options should be considered?
Soda
This method is absolutely safe, effective and has been tested for years. You need to pour water over the yellow stripes. Then apply an even and neat layer of soda.
We do this before going to bed. In the morning, we start processing the stripes with a sponge and press the drain. There should be no traces left.
Vinegar
This product is also often used to care for plumbing and has proven its effectiveness. Some people simply pour vinegar on the yellow stripes and treat them with a brush in the morning. But this method is not the most effective.
It's better to do it differently.
Take a paper towel and soak it thoroughly with vinegar. Spread it on the yellow marks. In the morning, remove the "compress" and go over it with a sponge.
The toilet will simply sparkle.
