Of course you can still use the toilet brush.
BUT keep in mind:
The toilet brush is the most unhygienic item in the household. In it, germs and bacteria that pose a significant health hazards multiply. Especially for toddlers, elderly or immunocompromised people, it represents a great risk. The use of the toilet brush also means that when removing feces easily tends to even quickly even once completely “wipe” through the toilet. However, you only distribute the germs and bacteria that have formed and multiplied in the toilet brush.
Furthermore, we all know the problem when using the toilet brush: dripping, splashing, unpleasant odor and over time, the toilet brush is no longer an optical pleasure.
