Review on Dico 541-780-21/2 Nyalox Cup Brush 21/2-Inch Orange 120 Grit by Anthony Lanka

Wonderful brush that doesn't damage tile or fiber glass. I used this on our walk in shower to clean the grout, tile and soap scum from the glad doors. I also used it on our soak tub. The tub has a textured bottom that would not clean worth a darn till this.Note that it is not effortless. I went through 2 18V batteries and my arm, hand and bicep were sore the next day. I also had to use a decent amount of non toxic cleaner and water as the brush works better with a lot is gritty and foamy cleaner to work into porous surfaces. I am going to user it on our drop top stove and double ovens next!
