Review on Chemical Guys Acc_201_Brush_HD Carpet Attachment by Reza Cook

After reading many reviews I decided to order the Revolver Drill Brush and the Hard Nylon Drill Cleaning Brush and this is a comparison of two brushes. For testing, I used them on both a tiled shower and a ceramic hob and sink. Both cordless drills I used were Milwaukee 18V low speed drills. I have used a variety of surface cleaners but none of them were harsh as I tested with brushes and not chemicals. The hob had burn marks and the shower and sink had iron stains and limescale but not too bad as I usually acid wash them to keep them clean. No doubt both brushes performed admirably, but there were minor differences. The revolver brush gets into corners easily because the bristles move outward with more RPM (hard nylon doesn't), but hard nylon cleans better. When using a stiff nylon brush, you must work in both directions, otherwise the bristles will gradually remain bent in the predominant direction. Both brushes removed iron stains quite easily, but it was more difficult with calcium (lime). I could see myself removing some grout (by color) so I'd advise not rubbing too hard. Using more harsh chemicals is probably your best bet, rather than a harsh approach. I was pleasantly surprised at how well the brushes worked on the hob. Here, a stiff nylon brush did a better job of singeing stains (permanently, I thought). They both worked, but the stiff brush was faster. After I cleaned and polished the record it looked like new again.
