The Coldest Water Bottle Brush: 3 Tools in 1

You can definitely clean all parts of your cup. I'm not sure what the little round brush is for. It would be nice if the small brushes folded into the big brush to consolidate the brushes. But otherwise pretty good.

I tried regular bottle brushes that wouldn’t reach all the way in to bottle but the Coldest brush i do not have that problem

Most people are looking for reviews on the cups, can they hold ice for a long time, what sizes do they come in, but hardly ever do we ask ourselves how do I clean the straw or how do I make sure nothing get stuck in the sip lid.

This is a must have. It comes with all of the cleaning utensils you need and is nicely clasped together with a ring so you don’t lose anything. Just hook it under your sink and you will always have it when you need it. I highly recommend that if you purchase any type of cup, add this to your cart.
