You can’t deny the facility of a dishwasher in your everyday life. Because it not only balances your everyday workload rather also helps you to maintain a healthy kitchen atmosphere. But today, we are not focusing on the dishwasher’s pros or cons.

Meanwhile, we will discuss what types of things are dishwasher safe. Actually, we have got enough inquiries on the question, “can you put a hydro flask in the dishwasher”?

With that said, we have decided to pen down the topic in detail. Let’s start with a brief, direct answer before an elaborate discussion.

Can you wash hydro flasks in the dishwasher? The answer is yes is some point and no in some manner. Why? Because not all type of hydro flask is dishwasher safe. More clearly speaking, hydro flasks manufactured before 2020 are not dishwasher safe. On the other hand, post-2020 hydro flask models are dishwashers safe.

Now the question will arise why it is like this? Bear with us for a details discourse.

Definition of a Hydro Flask

what is a hydro flask

Although hydro flash does not need recognition. Despite the fact, we have included the definition for those who are still getting familiar with the function of this super popular bottle. However, a hydro flask is a stainless-steel insulated bottle specially designed to keep water cold or hot simultaneously.

According to the hydro flask manufacturer, if you keep ice-cold water in the bottle, it will remain cold for up to 24 hours. Therefore, if you pour hot water, it will also be hot for up to 12 hours.

Because it is built with a combination of vacuum insulation and double-walled stainless-steel construction. The layout creates an insulated barrier that helps maintain the liquid’s temperature. As a result, keeping hot drinks hot and cold drinks cold for extended periods of time.

Additionally, hydro flask bottles often have a leak-proof cap or lid, which helps maintain the liquid’s temperature by preventing air from entering or escaping the bottle.

Speaking of the design details, it is available in various sizes, colors, and styles. And they are often used for activities such as hiking, camping, biking, working out, and even home use.

Lastly, hydro flask bottles are an eco-friendly alternative to disposable plastic water bottles, making them more attractive for everyday use.

Why Post-2020 Hydro Flask Models are Dishwasher Safe?

A new model of hydro flask bottles made after 2020 is safe for washing in a dishwasher because they are mostly constructed with power-coated material that allows you to put it in the dishwasher.

Since power coated is a kind of material that does not fade or corrosion easily and has heat resistance components. Besides, in the question-answer section of the hydro flask official website, they clearly define all hydro flask powder-coated bottles are dishwasher safe. On the other hand, hydro flask coffee mugs are not powder coated, and also they are not dishwasher safe.

However, for washing the bottle in the dishwasher, the manufacturer recommended putting them on the dishwasher’s top rack.

Although dishwasher safe, you can also hand wash them because the bottle does not require hard cleaning.

In a later section, we have also included how to clean a hydro flask bottle. Keep reading.

Why Are Pre-2020 Hydro Flask Models Not Dishwasher Safe?

Clearly, you might already understand why the pre-2020 model of the hydro flask is not dishwasher safe. Because they are not constructed with power-coated material and consequently don’t have heat and fade resistance components.

So, when you place them even in the top rack of your dishwasher, in that case, the machine’s heat and cleaning process will damage the bottle’s overall temperature system.

As a result, it will lose its efficiency in keeping water cold or hot for a long time. Eventually, those pre-2020 models are not recommended for washing in a dishwasher.

Can You Wash Hydro Flask Bottle Lid and Cap in Dishwasher?

Another question that is related to hydro flask cleaning is, can you put the hydro flask lid or cap in a dishwasher?

Again, the answer is no and yes.

No, because few pieces of research show if you put the lid or cap of a hydro flask in the dishwasher. The bottle’s insulation property becomes damaged by the high temperature of the washers and will react with the high-range detergent.

Contrary to this statement, other research claims all types of lids and caps of the hydro flask are absolutely dishwasher safe. 

Don’t worry about the different types of research arguments, as the hydro flask manufacturer clearly states on their official website, “All Hydro Flask Caps and Lids are Top Rack Dishwasher Safe.”But it’s advised to place them on top of the machine.


Although the official statement allows the lid and cap to wash in the dishwasher, it always prefers hand washing.
