Is Nalgene Bottle dishwasher safe?
Dishwasher safe✓ Verified
Yes — Nalgene says all of its bottles are dishwasher safe on the top rack.
Why
Nalgene bottles are made from durable Tritan copolyester or HDPE, and the company states they're dishwasher safe — just keep them on the top rack, away from the heating element, since direct high heat can warp even tough plastic. Caps with rubber gaskets, straws, or sip valves are better hand washed to protect those parts.
How to wash it
Unscrew the cap, empty the bottle, and put both on the top rack away from the heating element. Hand wash specialty caps (straw/sip) to preserve the seals.
