Review on Silicone Bottle Brush Multi-Pack: 3 Brushes + 1 Sponge - Effortlessly Clean Narrow Neck Containers, Vases, and Glassware by Brian Chatum

My husband and son fill up their water bottles daily. I bought a set of Little FootPrint silicone bottle brushes to make cleaning easier as the nylon bristle brush we used left streaks. Because the "bristles" of these brushes are thicker, it's easier to ensure each stain is thoroughly cleaned. A pleasant surprise came the day I decided to try, against my "common sense," to bend one of the brushes to make it easier to get to the hard-to-reach part of the large water bottle. He bowed! It wasn't so easy to bend that I was ready to bend it back when I was done, but it was easy enough that I felt it should bend. The smallest brush head is shaped to fit a baby bottle nipple perfectly and it was really handy for our doggie's water bottle as her bottle's mouth is smaller.
