Review on 🧹 HIGHWARE Straw Cleaner Brush Set – 8-Piece Long Cleaning Brush for Straws on Tumblers, Water Bottles, Sippy Cups, Pipes, Tubes, or Hummingbird Feeders by Julie Brown

I bought these brushes because I recently bought a contigo mug with a reusable straw. These straw brushes were perfect! As usual my vitamin drink leaves a residue/film in the cup and straw and these brushes cleaned it up straight away. It seems that when you pull the brush out of the straw, the bristles fold over and create friction that really scratches the sides of the straw walls. The bottom of the cup I bought is hard to reach so one day I decided to see if I could bend one of them and get on the bottom of the cup and it worked. It's not the ideal way to delete it, but it works. I would definitely buy them again!
