Their Printed Material Confirms This:
I recently bought a Hydro Flask 18 oz bottles as well as a 12 oz Kid’s bottle so I had a chance to look through the printed material to see what it said and to see if it conflicted at all with the online statement.
As you can see in the image above Hydro Flask state in their printed material Handwash only which means do NOT put your bottles in the dishwasher.
Soak The Exterior In Hot Water
The team at Hydroflask strongly advises their customers against soaking the exterior of their product in hot water.
Soaking the surface can cause the paint to peel and flake, and it can also affect the insulation and overall performance of the product.
Instead, Hydroflask recommends that their customers clean the exterior with a soft cloth and warm water. If there is a tough stain or dirt that needs to be removed, you can use a little bit of dish soap.
Are Hydro Flask Microwave Safe
Hydro Flasks are made almost completely of metal, so they cannot go in the microwave.
Why shouldnt metal hydro flasks go into a microwave? Metal is a huge conductor of electricity, and microwaves give off plenty of that.
When you use metal in the microwave, it can begin to spark and cause a fire, and even destroy the microwave itself.
Just not a great idea to be using your Hydro Flask in the microwave!
What is the best alternative to microwaving? You can always transfer the liquid into a microwave safe container, or heat up the liquid in a pot on the stove.

Can The Dishwasher Wear Down Your Hydroflask Overtime
If you are putting a Hydroflask that is dishwasher safe in the dishwasher, it shouldnt wear it down too much. It is possible for it to wear down a little bit faster than it would if you were to hand wash it every time. However, you wont be doing any damage.
The problem is when you put an old Hydroflask in the dishwasher. At minimum, you might get lucky and nothing bad will happen. At the most, the vacuum seal may get broken and your Hydroflask wont keep liquids hot or cold anymore.
Hydroflasks have two walls: An inner wall, and an outer wall. There is a vacuum seal in between these walls that works as insulation, keeping drinks hot or cold for a long amount of time. But putting your Hydroflask in the dishwasher will make it get really hot, and this could break the vacuum seal and compromise this effect.
Putting your non dishwasher safe bottle in the dishwasher could also cause some wear and tear. Your bottle might become dull, discolored, or flaky. So its definitely important to listen when your Hydroflask says that its not dishwasher safe.

Clean your Hydro Flask about once a month. Marcus Shields of Maideasy says: “To be safe, deep clean your Hydro Flask at least once a month. If you don’t clean it often enough, mold will grow under that rubber seal, and it will disgust you when you pull it off. “
