Yellow smudges in the toilet are often not rust, but plaque that appears due to hard tap water with impurities and chlorine.
No matter how you clean such a toilet, yellowness will still appear.
In order not to spend money on expensive chemicals, maids in Chinese hotels use this know-how.
Instead of cleaning gels, they throw used tea bags down the toilet and apply them to the dirty sides of the toilet.
After 20 minutes, the plaque oxidizes and can be easily cleaned with a regular brush.
Tea bags solve three problems at once - they remove yellowness and whiten the toilet bowl, clean it from harmful microflora, and eliminate unpleasant odors.
In addition, if you cover the toilet bowl with tea bags at night, then the ceramics will sparkle in the morning, like new.
No yellowness, limescale and unpleasant odors.
Cleaning the toilet with such a life hack will become easier and cheaper.
