Window Groove Cleaning Brush, Glass Groove Dead Corner Cleaning Brush, Household Window Gap Scanning Window Gap Cleaning Tool

It works to remove stains from toilet bowl.

Still have to use it.

It arrived quickly, we'll see how it works. I add review: it's great, about 10 years old it's pitch black, I've tried all the cleaning methods found on the internet, but with zero results. But with the help of this stone I cleaned more than half (how dirty it was, I probably needed 2). I will definitely order again 👍

I like it, I can carve the toilet without much effort and it cleans it very well.

Very weak, very soft material, DOES NOT do what it says, I do NOT recommend .
