Keep your water bottles clean with this brush set
by Mark Frauenfelder from on (#2FAY8)
If you use a water bottle you may have noticed that no matter how much you wash them, they still retain a musty smell. This bottle brush set from OXO Good Grips has three brushes to take care of that problem. One cleans the inside of the bottle, one cleans the cap, and the third cleans the straw (if it has one). It's $10 on Amazon.
