Are Hydro Flasks Dishwasher Safe?

Hydro Flasks are one of the most popular reusable bottle brands on the market. These insulated bottles have exploded in popularity over the last few years, mostly due to their incredible quality and great style.

Hydro Flasks are vacuum-insulated, made with high-quality materials, and come in a wide range of attractive designs. But can you put your Hydro Flask in the dishwasher?

If you need to wash your Hydro Flask but you aren’t sure whether or not it’s dishwasher safe, don’t worry! In this handy guide, we’ll take a look at whether or not a Hydro Flask is dishwasher safe, what types of Hydro Flasks can be put in the dishwasher, as well as how you can hand wash your Hydro Flask.

So read on, and we’ll teach you everything you need to know!

Can You Put Hydro Flasks In The Dishwasher?

So are Hydro Flasks dishwasher safe? Well, as it turns out that’s kind of a tricky question to answer, and there are a couple of factors that determine whether or not you can put your Hydro Flask in the dishwasher.

The main way to tell if your Hydro Flask is dishwasher safe is when it was made. All Hydro Flasks made in 2020 or after that are completely dishwasher safe and can go in without any worries.

This is because of changes to their design, which makes their non-slip powder coating and insulation safe to go in the dishwasher. So if you aren’t sure about putting your Hydro Flask in the dishwasher, think about when you got it and whether it was new.

Meanwhile, all Hydro Flasks made before the design change in 2020 can’t be put in the dishwasher as this can damage or break them. This is because the previous design of the bottle meant that the dishwasher could compromise the insulating vacuum seal.

If you don’t know when your Hydro Flask was made, you can tell by looking at the neck of the bottle; the older design has a stainless steel neck with external threading to screw the cap on, while newer Hydro Flasks only have a small stainless steel lip with the threading on the inside.

Alternatively, you can always take a look at the manufacturer’s instructions on the packaging. These won’t just tell you whether or not you can put your Hydro Flask in the dishwasher, but will also provide instructions on how best to wash your Hydro Flask.

What Hydro Flasks Aren’t Dishwasher Safe?

Now that we’ve covered which Hydro Flasks are dishwasher safe, let’s take a closer look at what ones aren’t.

As we’ve already covered, older Hydro Flasks made before 2020 can’t be put in the dishwasher. This is because the heat on a dishwasher can compromise the vacuum insulation that makes Hydro Flasks so effective at maintaining their temperature.

Additionally, the non-slip powder coating on older Hydro Flasks can get damaged or discolored when submerged in hot water for extended periods of time.

However, just because newer Hydro Flasks are dishwasher safe it doesn’t mean that you should put them in the dishwasher. While the new design is theoretically dishwasher safe, this isn’t always the case. Longer and/or hotter cycles are still more than capable of damaging the seal of your Hydro Flask, and it only takes a tiny compromise to the vacuum for it to lose its insulating properties.

The same applies to the powder coating, which can still be damaged or discolored if submerged for long enough.

Not every style of Hydro Flask is 100% dishwasher safe, either, and this includes bottles with the new design. Depending on the style of Hydro Flask, there may be parts that are either top-rack wash only, or can’t go into the dishwasher at all.

These include parts like straws and most lids (apart from the Hydro Flip Lid, Wide Mouth Straw Cap, and Wide Mouth Flex Sip Cap), none of which are dishwasher safe. Many types of the bottles themselves are also only suitable to be put on the top rack of the dishwasher on a gentler cycle.

So while newer Hydro Flasks are technically dishwasher safe, you may still be better off washing them by hand like you would with an older design.

How To Hand Wash A Hydro Flask

If your Hydro Flask isn’t dishwasher safe, then you’ll have to wash it by hand. Luckily, handwashing your Hydro Flask is quick and easy to do!

Using some hot, soapy water, rinse and wash out the inside of your Hydro Flask. Make sure that the water isn’t too hot that it might damage your bottle, but is hot enough to clean the bottle thoroughly; because handwashing your Hydro Flask doesn’t take anywhere near as long as putting it in the dishwasher, you can get away with slightly hotter water.

Cleaning the inside of your Hydro Flask can be a bit trickier, but you can get a handy Hydro Flask bottle brush to make this much easier. Alternatively, you can use a cloth, sponge, or another type of bottle cleaning brush to do this too.

If your Hydro Flask has some stubborn stains or smells that you can’t shift with soap and water alone, then you can shift them with a quick and easy trick. Simply add some lemon juice to the bottle and top it up with warm water. Then, leave it to soak for half an hour before rinsing it out.

To get rid of lingering smells, add a few tablespoons of baking soda and dissolve it in warm water. Leave it for 15 minutes, rinse it thoroughly, and let it air dry. The smell will be gone!

Final Thoughts

Now you know all there is to know about washing your Hydro Flask, from how to tell whether it is dishwasher safe to how you can hand wash your Hydro Flask.

While all Hydro Flasks made during or after 2020 are theoretically dishwasher safe, you might still be better off washing them by hand. However, there’s still nothing wrong with putting them in the dishwasher as long as you make sure it’s on a faster, cooler setting.
