Can You Wash Hydroflasks In The Dishwasher

In today’s fast-paced world, convenience is key. We look for ways to simplify our daily routines, even when it comes to the most mundane tasks like washing dishes. Hydroflasks, the popular stainless steel water bottles known for their durability and ability to keep beverages cold or hot, have become a staple for many. But can you toss them into the dishwasher for a quick and easy clean? In this article, we’ll explore the dos and don’ts of washing Hydroflasks in the dishwasher.

Hydroflasks have gained immense popularity for their quality and ability to keep beverages at the desired temperature. However, the question that often arises is whether you can save time and effort by washing these stainless steel wonders in the dishwasher.

Understanding Hydroflasks

Before delving into the dishwasher debate, it’s essential to understand what Hydroflasks are made of. These bottles are constructed from high-quality stainless steel, known for its resistance to rust and corrosion. They also feature a double-wall vacuum insulation, which is responsible for maintaining the temperature of your beverages for extended periods.

The Appeal of Dishwasher Cleaning

Dishwashers offer a quick and convenient way to clean various kitchen items, from plates and glasses to cutlery and cookware. It’s no wonder people wonder if they can include their Hydroflasks in the dishwasher load.

The Risks of Dishwashing Hydroflasks

While the idea of a hassle-free clean is tempting, it’s important to note that dishwashers may not be the best option for Hydroflasks. Here are some reasons why:

  • Heat and Pressure: Dishwashers use hot water and high-pressure jets to clean dishes. This combination can potentially damage the insulation of your Hydroflask, affecting its performance.
  • Chemical Detergents: Dishwashing detergents can be harsh on stainless steel and may lead to discoloration or loss of the bottle’s original shine.
  • Small Parts: Hydroflasks often have small, intricate parts like lids and seals that may not withstand the dishwasher’s rigorous cleaning process. They could warp or become damaged.

Proper Care and Maintenance

To ensure your Hydroflask continues to serve you well, it’s best to follow the manufacturer’s care instructions. Typically, they recommend handwashing the bottle with warm, soapy water and a non-abrasive brush. This method ensures that the bottle stays in excellent condition.

Handwashing Hydroflasks – The Safe Approach

Here’s a simple step-by-step guide to handwashing your Hydroflask:

  1. Disassemble: Remove the lid and any other detachable parts.
  2. Rinse: Rinse the bottle and its parts with warm water to remove any residue.
  3. Soapy Solution: Fill the bottle with warm, soapy water and let it sit for a few minutes.
  4. Scrub: Use a soft brush or sponge to scrub the interior and exterior of the bottle. Pay extra attention to areas with stubborn stains.
  5. Rinse Thoroughly: Rinse the bottle and all its parts thoroughly to remove any soap residue.
  6. Dry: Allow the bottle to air dry completely before reassembling.

Alternative Cleaning Methods

If you’re concerned about the cleanliness of your Hydroflask but want to avoid the dishwasher, there are alternative cleaning methods you can try:

  • Vinegar and Baking Soda: Create a mixture of vinegar and baking soda to clean and deodorize your Hydroflask.
  • Hydrogen Peroxide: Dilute hydrogen peroxide with water and use it to clean the bottle and its components.
  • Bottle Cleaning Tablets: Some companies offer specialized cleaning tablets designed for stainless steel bottles.


In conclusion, while the dishwasher may seem like a convenient option, it’s not the best way to clean your Hydroflask. The risks associated with heat, pressure, and harsh detergents can outweigh the convenience. Instead, opt for handwashing or alternative cleaning methods to ensure your Hydroflask remains in top-notch condition. Remember, proper care and maintenance will prolong the life of your beloved bottle.
