Susimond Magic Window Cleaning Brush, 3PCS Window Groove Cleaning Brush with 6 Replacement Pads, Hand-held Crevice Cleaner Tools, Window Track Cleaner for Corners Window Slides Gaps Blind Track

We have an older house. The metal trim on the windows needed some sprucing. This was the best kit for it. I also used them to clean my washing machine, the impossible spot of the fireplace where the doors slide, trim on the inside of the refrigerator, my oven, etc. So many uses. The scrubbers last a long time.

This allows you to clean your window tracks easily and thoroughly. It would also be very helpful for cleaning shower tracks. It adjusts to the task well cleaning both sides of the rail well. Simple but effective. I will purchase it again when the pads wear out as this was so good.

My wife loves these. They work great.

cheap materials, I could have put something together myself

Does not fit into the window gap and does not work at all.
