How To Keep Your Water Bottle Healthy
Regardless of which bottle you choose, it’s important to follow a few steps to make sure it stays clean, and to prevent ingestion of harmful germs. Clean your bottle daily to keep it free from any saliva buildup or tiny food particles that can cause bacteria growth. Be sure to use warm water and soap.
Focus on the mouth and cap. These places, along with any textured surface (like ridges to screw on a lid), harbor the most bacteria. Spend a few extra seconds scrubbing them.
Use bleach. Mix a solution of 1-teaspoon bleach and a half-gallon of water to disinfect weekly. If your bottle has a sport cap, flip it open and submerge in the solution for 1 minute. Rinse under running water, then squirt a full bottle of clean water out through the cap.
Air it out. If you aren’t immediately refilling your bottle, invert it on an angle to dry so air can circulate through.
