Review on Long-Handled V-Shaped Grout Brush With Hard Bristles For Effective Window Track And Crevice Cleaning - Perfect Corner Scrubbing Brush Scrubber by Becky Taylor

I use this for my standing shower which is covered in tiles from floor to ceiling. I can't reach most tiles because the walls are too high and I can't get on all fours anymore to scrub the bottom corner areas.I like this grout brush because it's adjustable but I try to scrub as gently as possible because I have read from other grout brush products that usually aluminum handle would break if you put too much pressure.
