It’s such a clever design, because it eliminates the issue of dirt and grime getting stuck in between bristles and under where they are attached to the wire handle of a more traditional brush

They don't get all full of bacteria like the sponge brushes get and if you want to sanitize them put them in the dishwasher

These bottle brushes are attractive and work well

I like to reuse the huge water bottles but they were hard to get clean until I got these

I will recommend to my fitness friends who struggle to keep their sports bottles clean too! Finally! A brush I can use to actually reach inside of my metal water bottle and get it CLEAN! I love this brush duo

It's pretty much impossible to clean out your water bottles with a dish rag and even the water bottle cleaners with bristles don't clean the bottom of the bottles well
