It's important to clean the inside of your reusable water bottle to remove grime, mildew and bacteria. But it can be very difficult to get a brush through the narrow opening and scrub the bottle clean. Instead, fill half the bottle with a mixture of white vinegar and water, then add several ice cubes and screw on the cap. Shake vigorously. The vinegar will disinfect, and the ice will agitate inside, loosening any grimy mess. Dump, rinse with water and voila! A perfectly clean water bottle.
