We love this brush set! We have several stainless steel water bottles of various sizes (including HydroFlask) and with different types of tops – some unscrew, some have flip lids, some with an attached straw etc. This tool covers ALL parts of the water bottle. We drink a lot of tea and this does a great job at getting out tea stains at the bottom of the bottle (our regular kitchen scrub brush is too wide to fit inside).
The short brush is great for getting into the crevices of the lid, you’d be surprised how much stuff gets stuck in there, gross!!! The thin brush is ideal for cleaning out the inside of straws which is great! I also have used this thin brush for other plastic and metal reusable straws we have at home.
