This step-by-step guide will help you to properly clean your Hydro Flask for use. Tips for cleaning your lid and straw lid are also included. Stop smells and have your hydro flask looking like new. Check out how to clean a hydroflask and lid.
I recently bought a hydro flask and am very happy with it. It holds 32 ounces and fits great in the cupholder at the gym.
The one downside to it is it isn't dishwasher safe. It's easy enough to clean by hand if you know what you are doing.
If you want to clean hydro flasks to keep them clean and free from bacteria, plus free from stubborn stains check out these tips below.
How To Clean A Hydroflask
To wash your hydro flask you will need a few things.
- Dish soap (I prefer blue dawn)
- Bottlebrush (I use this one)
- Straw Brush (I have this one from Amazon)
- Microfiber cloth
It only takes a few minutes to clean your hydroflask, but I do recommend you give it time to dry before putting it away. If not you risk mold or mildew build-up.
Getting Started
You will want to start by hand washing the inside of your hydroflask. They are not dishwasher safe so never put them in the dishwasher to clean them.
Cleaning Your Hydroflask Bottle
Step 1: Add about 1/2 teaspoon of dawn dish soap to the bottle. Then fill the bottle up with hot water.
Step 2: Use the bottle brush to scrub the inside of the hydroflask. Make sure you scrub the walls down really well especially if you put something other than water in your bottle.
Step 3: Let the warm soapy water sit in the bottle for a few minutes.
Step 4: Pour out the soapy water and rinse the inside of the bottle. I like to use the bottle brush again to make sure I have removed all the soap residue from inside.
Step 5: Now you can move on to cleaning the lid. This will vary based on what kind of lid you have. The screw-top lid or hydro flip lid can just be wiped down with hot soapy water and a microfiber cloth.
Step 6: If you have a straw lid or wide straw lid you will probably want to use a straw brush (I have this one from Amazon) Soak the lid in some hot soapy water for a few minutes.
Step 7: Use the straw brush to gently clean inside the lid and the mouthpiece.
Step 8: Use the straw brush to clean out the straw.
Step 9: Rinse the lid and allow to air dry.
Getting Rid Of Smells
Still dealing with a smelly hyrdoflask? You can try a few things.
If the inside of your water bottle still smells at this point and time you can add about 2 tablespoons of white vinegar and fill with warm water.
Then, let it soak for about 10 minutes and rinse. (Note: Never use bleach in your bottle)

If your cap still has an odor it could be the hydroflask ring. You can either replace the ring (amazon sells them) or you can clean it.
I don't recommend using vinegar on the ring because it may absorb the odor.
You can use baking soda to get rid of any smells on your o ring. Just make a baking soda paste and rub it over the ring. Let it sit for about 10 minutes and then rinse with hot water.
Getting Rid Of Rust When Cleaning Hydroflasks
Stainless steel water bottles are not rust proof. If you need to get rid of rust add enough lemon juice to cover the rusted area and let soak for about 30 minutes.
Then, you can use a mix of baking soda paste to rub away any rust.
Hydroflasks come with a limited lifetime warranty against defects so taking good care of your bottle is important so you can enjoy it for years to come.
