Are Hydroflasks Dishwasher Safe Reddit

As an avid user of Hydroflasks, I understand the importance of keeping our reusable water bottles clean and safe to use. With their sleek design and ability to keep drinks hot or cold for hours, Hydroflasks have become a popular choice among outdoor enthusiasts and everyday individuals alike. However, one question that often pops up among Reddit users is whether or not Hydroflasks are dishwasher safe. In this article, I will delve into this topic and provide you with all the information you need to know.

Understanding Hydroflask Materials

Before we dive into the dishwasher safety of Hydroflasks, let’s take a moment to understand the materials they are made of. Hydroflasks are constructed with stainless steel, a material known for its durability and resistance to rust and corrosion. The double-wall vacuum insulation in Hydroflasks helps maintain the temperature of your drinks for extended periods of time. The exterior of Hydroflasks is finished with a proprietary powder coating that adds an extra layer of protection while giving them a vibrant and attractive look.

Manufacturer’s Recommendations

When it comes to cleaning your Hydroflask, it’s always best to follow the manufacturer’s recommendations. Hydroflask explicitly states on their website that they do not recommend putting their bottles in the dishwasher. While the stainless steel and powder coating are dishwasher safe, the vacuum insulation and other components of the bottle may be compromised by the dishwasher’s high heat and harsh detergents. To ensure the longevity and performance of your Hydroflask, it is best to hand wash it with warm water and mild detergent.

Community Experiences on Reddit

Now, let’s tap into the collective wisdom of the Reddit community and see what users have to say about dishwasher safety for Hydroflasks. While some Redditors claim to have successfully washed their Hydroflasks in the dishwasher without any issues, there are also numerous reports of negative experiences.

One Reddit user shared their unfortunate experience of putting their Hydroflask in the dishwasher, only to find the powder coating peeling off after a few washes. Another user mentioned that their Hydroflask lid became warped and no longer fit properly after being washed in the dishwasher. These anecdotes highlight the potential risks associated with using the dishwasher on your Hydroflask.

It’s worth noting that Hydroflask customer support also emphasizes the importance of hand washing their bottles. They state that dishwasher use may void the lifetime warranty, which further underscores the potential risks involved.

My Personal Recommendation

Based on the manufacturer’s recommendations and the experiences shared by the Reddit community, my personal recommendation would be to avoid putting your Hydroflask in the dishwasher. While it may seem convenient, the potential risks of damage to the vacuum insulation and powder coating outweigh the benefits of saving a few minutes in cleaning time. Instead, take the time to hand wash your Hydroflask with warm water and mild detergent. It will not only help maintain its longevity and functionality but also ensure that you can continue enjoying your favorite beverages at the perfect temperature for years to come.


In conclusion, Hydroflasks are not recommended to be put in the dishwasher according to the manufacturer. Although some users on Reddit have reported success with dishwasher cleaning, there are also numerous accounts of damage occurring to the bottle and its components as a result of dishwasher use. To be safe, it’s best to hand wash your Hydroflask following the manufacturer’s guidelines. By taking this extra step, you can prolong the lifespan of your Hydroflask and continue to enjoy its insulation properties for many adventures to come.
