Review on 🧽 Window Groove Gap Cleaning Brushes for Hand-held Window Track and Kitchen Cleaning Tools - 8 Pieces (Pink, Green, Blue, Black) by Jenny Hupke

I am buying this for sliding door rails in the deli display case at the grocery store where I work. These brushes are the best brushes we've found for cleaning tracks and removing dirt from corners. I just want the bristles on the brush to last longer. They are used daily and the bristles bend slightly after about a month, the bristles are so bent that we have to throw the brush away. Luckily there are six of these in the pack so they should last around 6 months.
