Hydro Flask says its powder coated bottles and tumblers are dishwasher safe, but its coffee mugs are not. Dishwasher damage to the coating is not covered by the warranty, so hand washing is the safer choice for the finish.
The steel body handles the dishwasher without any problem. What changes over time is the colored exterior, the lid seals and the small parts. If you care about the color staying vivid, hand washing keeps the finish intact, and it only takes a minute.
| Short answer | Bottles and tumblers yes, coffee mugs no |
|---|---|
| Body | Stainless steel, which tolerates the cycle |
| Finish | The colored coating wears faster in the dishwasher |
| Lids and seals | Separate lids and straws and put them on the top rack |
| Best rack | Top rack |
How to wash a Hydro Flask
- Check the care guidance for your exact bottle and lid.
- Unscrew the lid and remove any gasket or straw that comes out.
- Wash on the top rack, or by hand with warm water and a bottle brush.
- Rinse well and let it dry upside down with the lid off.
- Descale the inside with vinegar and water if you notice a smell.
What happens when you get it wrong
- Fading or scuffing. Dishwasher cycles wear the colored coating, especially at high heat.
- Smelly lids. Seals that are not dried fully hold moisture.
- Lost parts. Small gaskets and straws can fall through the rack.
Hand washing with a bottle brush, which also cleans the bottom edge.
A short soak in warm water and vinegar to remove smells.
