Why should I hand wash my water bottles (even the dishwasher safe ones)?

Bulletin Bottle [.com] recommends hand washing all of our water bottles (even the dishwasher-safe ones). Why? Good question! Here are our top three reasons:

1. Over time, repeated hot water machine-washing can cause the imprinted artwork on your bottle to fade, peel, or crack.

2. The rubber and silicone seals used to keep liquids in the bottle can break down and cause a leak.

3. Even the best dishwashers usually can’t get the insides of water bottles as clean as a bottle brush and elbow grease.
