I used it to remove iron rust attached to stainless steel pipe.
It was a pleasant task as rust of Milumyu Iron came out.
The surface of pipe of stainless steel pipe also becomes beautiful like being polished.
However, since the line of the brush is thin, when you work with bare hands, occasionally the fingertip seems to have been stabbed with a needle, so please be careful.
Because it hurt, I used a glove from the middle.
I also think that I will purchase.
