This is a great grout brush. The bristles on the end are very firm and rough which makes it great to clean grime and hard to clean surfaces. I actually use grout brushes to clean decal residue off my trailer when changing decals. I spray WD40 on my trailer and then use the grout brush to scrub the WD40 into the sticky residue from decals and it works great just takes some time scrubbing. Overall, this is an awesome grout brush and great deal for the price.
