Are Hydroflasks Dishwasher Safe?

Hydro flasks are popular for keeping beverages cold or hot on the go. 

They cost less than other insulated bottle brands and come in a wide range of options. However, when you decide to wash them, you may wonder if they are dishwasher safe.

Allow me to brief you on whether Hydroflasks are dishwasher safe and how to clean them thoroughly to maintain their performance.

Are Hydroflasks Dishwasher Safe?

Yes, Hydro flasks are dishwasher safe, but only if they are powder-coated bottles. 

According to HydroFlask, all powder-coated bottles can be safely placed in the dishwasher for thorough cleaning. 

These are the ones manufactured after 2020, featuring a stainless steel band on the collar side and no registered trademark symbol.

However, not all Hydro Flask products are dishwasher safe. For instance, Hydro Flask coffee mugs that aren’t powder-coated should be washed by hand. 

Additionally, it is generally recommended to hand wash all insulating mugs and tumblers to ensure proper care and prolong their lifespan.

Although powder-coated Hydro Flask bottles are dishwasher safe, make sure you follow the manufacturer’s guidelines for proper cleaning. 

It’s important to avoid using incorrect methods or cleaning agents that could potentially damage your Hydro Flask’s functionality or appearance.

The Manual Way

If you’d prefer to clean your Hydro Flask manually or own a non-powder-coated bottle manufactured before 2020, hand washing is the way to go. 

Here are some easy steps to clean your Hydro Flask by hand:

  • Empty Your Hydro Flask before you start the cleaning process.
  • Take apart the lid and any other attached components to clean them thoroughly.
  • Gather a bottle brush, warm soapy water, and a soft cloth or sponge. You may also use a mixture of baking soda and water or cleaning tablets for a more thorough cleaning.
  • Using the bottle brush, scrub the inside of your Hydro Flask with warm soapy water or the baking soda mixture. 
  • For the exterior, use a soft cloth or sponge to avoid scratching the bottle’s surface.
  • After cleaning the bottle, rinse it thoroughly with warm water to remove any soap residue.
  • Let your Hydro Flask air dry completely before putting them back together. 
  • Make sure to store your Hydro Flask with the lid off, which helps to prevent unwanted odors or mold growth.

How to Clean Hydroflask Caps and Lids

Cleaning your Hydroflask caps and lids can be done in two ways: using a dishwasher or cleaning manually.

Dishwasher Cleaning

All Hydro Flask caps and lids are top-rack dishwasher safe. To clean them in the dishwasher, follow these simple steps:

  • Remove the caps and lids from your Hydroflask bottles.
  • Place them on the top rack of your dishwasher, ensuring they are stable and won’t fall during the washing cycle.
  • Run your dishwasher using a regular or gentle setting, depending on your appliance’s options.
  • Once the dishwasher cycle is finished, take out your caps and lids and let them air dry.

Manual Cleaning

If you prefer to clean your Hydroflask caps and lids by hand, you can use warm soapy water and a straw and lid cleaning set. Here’s how to proceed:

  • Prepare a bowl of warm, soapy water.
  • Disassemble your caps and lids as needed, including removing straws if your lid has one.
  • Soak the caps, lids, and straws in the bowl of water for a few minutes to loosen any dirt or residue.
  • Use the straw and lid cleaning set to scrub the inside and outside of your caps, lids, and straws thoroughly.
  • Rinse all the parts with clean water to remove any soap residue.
  • Allow the caps, lids, and straws to air dry completely before reassembling and using them.

In case of stubborn dirt or odor, you can also use cleaning tablets specifically designed for Hydroflasks. Just dissolve a tablet in a bowl of water and follow the instructions provided on the package.

Removing Tough Stains and Rust From Hydroflask Bottles

Despite being made of high-grade 18/8 stainless steel, Hydroflask bottles may encounter some rust due to exposure to acids or bleach-based solvents. 

Dishwashing Liquid

One method for tackling stains on your Hydroflask is to create a cleaning solution using warm water and a small amount of dishwashing liquid. 

Fill your bottle with the mixture and let it sit for a few minutes before giving it a thorough shake. Proceed to empty the contents and rinse with warm water. 

For stubborn stains, using a soft microfiber cloth to lightly scrub the area may be necessary.

Baking soda and Vinegar

To address rust issues, you can use a combination of baking soda and vinegar. Start by mixing a paste of baking soda and a moderate amount of water. 

Apply this paste to the rusted area, and then pour white vinegar over it. Allow the concoction to work its magic for about 30 minutes to an hour. 

Once the time has elapsed, gently scrub the rusted area with a soft brush or cloth. Carefully wash the bottle using warm water to ensure no residue is left behind.

Cleanliness and Maintenance Frequency for Hydroflasks

To maintain their efficiency, it is essential to clean and maintain them properly. Regular cleaning ensures that your Hydroflask stays fresh, odor-free, and ready for your favorite drinks.

Even if you only use your Hydroflask for water, clean it daily. As a general rule, you should rinse your Hydroflask daily with warm water and give it a thorough cleaning around once a week. 

If, however, you’re using it for beverages other than water, it’s best to wash it daily or immediately after each use to prevent stains and odors.

Neglecting to clean your Hydroflask can lead to unpleasant consequences. 

Over time, bacteria and mold can build up inside the bottle, making your drinks taste unpleasant and potentially posing a risk to your health. 

Regular cleaning helps prevent this buildup, ensuring your Hydroflask remains a safe and enjoyable way to stay hydrated.

Hydroflask Cleaning DO’s and DON’Ts

There are a few dos and DON’Ts to ensure that your Hydroflask bottle remains in the best possible condition. 

DO’s:

Hand wash your Hydroflask as often as possible. Although powder-coated Hydroflasks are dishwasher safe, hand washing is the recommended method for optimal cleanliness. 

This helps to maintain the integrity of the bottle’s vacuum seal, paint, or powder coating.

Use a soft sponge or brush when washing your Hydroflask to prevent scratches. Opt for a brush with a long handle to easily clean the interior.

Clean your Hydroflask with a mixture of warm water and mild soap. This combination is effective in removing residue and eliminating odors.

Disassemble your Hydroflask before washing, including removing the cap, boot, and straw if applicable. This will allow you to thoroughly clean every component.

Regularly rinse your Hydroflask with warm water between uses to minimize buildup and maintain freshness.

DON’Ts:

Do not use harsh detergents or abrasive cleaners, as they can damage the vacuum seal, paint, or powder coating of your Hydroflask.

Avoid using metal or sharp utensils when cleaning the interior of your bottle, as they can cause scratches.

Do not store your Hydroflask with the cap or lid tightly sealed when not in use, as this can promote bacterial growth. Leave the cap slightly open to allow air circulation.

Forgo placing your Hydroflask in the freezer, as it can cause damage to the insulation and vacuum seal.

All powder-coated Hydro Flask bottles are dishwasher safe, thanks to the use of Color Last powder. This design change occurred in 2020.

To extend the lifespan of your Hydroflask mug, it’s recommended to clean it by hand.
