Universal Double-Ended Track Cleaning Brush 5 "Brilliant !" Mrs Bryant 20 July 2020 I wish I had bought one of these years ago! I have spent years using an old toothbrush, bottle brush etc trying to clean the shower track. This brush does the job, gets in to all the narrow track and fiddly corners and being long I don’t have to crawl inside the shower to reach. The wider brush is good for tiles and other surfaces.
