How To Clean Hydro Flask – The Handy & Efficient Way

Have you already got your Hydro Flask? I heard about the Hydro Flask a few months ago. My friend and I were just chatting, when she mentioned a water bottle that could keep temperatures steady.

The conversation really made me want to discover more about this intriguing water bottle. As I discovered more, I became more and more interested. After a couple of days of research, I decided to get my husband a hydro flask.

I figured that John should have one since he always brings coffee to work and complains how he drinks it cold every morning.

At first, he was very skeptical about it. He didn’t believe that it would be any better than what he had already been using. But after the first time that he used it, he started bragging about how amazing it is.

He interested all of his friends and colleagues into getting them, and he even got one for each of our boys.

The Hydro Flask put a smile on each of their faces.

What Is A Hydro Flask?

It is a water bottle advertised that it can keep cold liquids cool for more than 24 hours, and hot liquids warm for more than 12 hours.

It is made with food-grade stainless steel and a double-wall vacuum insulation that can keep temperatures steady.

The lightest bottle in the insulated hydration category, hydro flask has a small metal disk that absorbs moisture and gasses in the vacuum process.

The thin wall design keeps your drink cold even on a sunny day, and your hot beverage steady even in winter. If you put some ice in your hydro flask, it is guaranteed that it will stay there for hours.

The outside temperature won’t affect your drink. No matter the temperature of the drink or outside, the bottle will be comfortable to hold.

Furthermore, it is highly resistant to absorbing bacteria, odor, and taste, and it is also one-hundred-percent recyclable.

All Hydro Flask bottles are BPA free. BPA is an industrial material that is used to make plastics.

Research has found that it can seep into food or drinks without you noticing. It can have a bad effect on the blood pressure, brain, behavior, and health of fetuses, toddlers, and children. It is designed for the various occasions and situations – your imagination is the limit.

Common Mistakes When Washing A Hydro Flask

Putting your Hydro Flask in a dishwasher or exposing its exterior to hot water will affect the inner insulation. The dishwasher can get hot enough to damage it.

I discovered that when it was already too late, so John had to buy new flask when he noticed that the temperature of his coffee started getting cooler and cooler after the same amount of time spent in the bottle.

We were all pretty disappointed when it happened, but also sort of relieved when we found out that it was my fault, and that the water bottles are actually fine.

There really is no point in putting your flask in the freezer, since the outside temperature literally has no effect on the temperature of your drink. If you want to make your drink colder, try putting ice cubes in it.

Putting your bottle on the stove will not make your drink any warmer, it will just damage the outside of your flask.

Chemicals like bleach and chlorine will just ruin the stainless steel, so don’t even try using it on your Hydro Flask.

If you have been making any of these mistakes on a regular basis, it is time for you to get a new flask and start washing it properly.

Why Do I Have To Clean Hydro Flask?

Every time you take a sip of your drink, it will lead to germs spreading on your bottle. If that isn’t enough, bacteria can also accumulate on your bottle.

If you don’t clean it regularly, it will just get harder to clean once you finally decide to do it.

Yes, your stainless steel bottle is resistant to rust, but it can still experience rusting. That will require you to clean it with an appropriate cleaning solvent.

It can become extremely dirty if it isn’t maintained properly. It can even experience discoloration.

Remember that there is no reason for you not to clean it because it is so easy. It is even easier to clean than a plastic water bottle. Stainless steel is much stronger and better at repelling bacteria.

The spots can be really stubborn, and the stains will get harder and harder to clean. Discoloration is also a common problem with Hydro Flask.

But don’t worry, because there is a solution for every single one of the problems.

The Right Way

It is made of stainless steel, which makes it harder to rust than any other water bottle, and that is why it is really easy to clean.

As I said, it is vital to clean them regularly.

There are plenty of ways to clean it:

  • It is recommended to use a bottle brush while cleaning it. And you should make sure that you use that brush as often as possible.
  • You can use white distilled vinegar for cleaning it. It will help you remove any stains or discolorations on the inside of your Hydro Flask. I usually put one-half of a cup of vinegar in the flask, next thing to do is to gently swirl it around the flask so that it can wash any affected areas. After that I let it sit for around 5 minutes. Once that is completed, I just rinse it out with warm water, and sometimes I even repeat the process if it’s needed.
  • If there is a spot on your flask that just won’t go away, what you need is baking soda. Just mix 2-3 tablespoons of baking soda with a bit of warm water to form a paste. Dip your bottle brush into the paste and rub it into the spot inside of your flask. Repeat it as many times as you have to until the stubborn spot is finally gone.
  • You can wash your Hydro Flip Lid and Wide Straw Lid in the dishwasher. The dishwasher doesn’t have a positive effect on them, but if they need to be deep cleaned, it is acceptable.
  • The basic soap-and-water technique is also good for everyday cleaning. Use it with your bottle brush to clean the dirt left from your drink or food.
  • If the stains are tough, you can also use detergent with your bottle brush. That way, you will clean your Hydro Flask more efficiently. This is used for cleaning the fingerprints off your bottle. Prints appear especially if you’re consuming greasy food or sweating heavily while using your Hydro Flask.
  • For the stubborn stains or spots, or even light rust stains, use non-scratching creams or polishes (with your bottle brush, of course). After that, you should rinse your flask with water. And when you’re done with that, dry it with a clean towel or cloth. Remember to avoid using drying pastes.
  • To avoid water stains on your bottle, you should use non-mineral water when cleaning it.

After washing your Hydro Flask with any of the solutions above, you should let it dry upside down. Air drying your flask is the best way to dry it because it will prevent it from collecting bacteria.

  1. Hi there. Any tips on how to clean water marks from the outside of the HF? Someone accidentally put mine in the dishwasher – it didnt seem to cause any issues in its ability to keep things cool – but its covered in these water marks now.

  2. Dear Nancy,

    I feel your pain. This happened to my son too. I asked him to turn on the dishwasher after he got back from his training. Silly boy was in a rush, and he placed his hydro flask in the machine. He realized he made a mistake a few minutes later, but it was already too late.

    However, we did find a way to clean the stubborn water stains.

    A good non-scratching cream or polish along with some cold water and a gentle brush does the trick.

    Make sure that the paste you are using doesn’t include any abrasive or soft calcium carbonate additives. Stay away from chloride solutions as well.

    Once you apply the right non-scratching cream and brush the stain out, rinse off the added residue with clean non-mineral water. It is crucial to use non-mineral water to avoid new watermarks.

    If you want to make sure there are no drying marks, you can use an air blower instead or wipe the area with disposable clean wipes.

    Your hydro flask will be as good as new.

    Let me know if you need any additional help.

    Love,

    Barbara

  3. How do I remove the awful smell inside my daughter’s Hydro Flask? I’ve tried white vinegar, soap and water, nothing works!
    She put some flavored water in it!

  4. Dear Jamie,

    Try with the old faithful – baking soda. This method takes a while but should deliver.

    Fill the flask with hot water.
    Add 2 teaspoons of baking soda.
    Leave to stand overnight.
    Rinse out thoroughly the next morning and dry.

    Let me know how it went!

  5. My husband accidentally put his in the dishwasher. I am so thankful I found your solution to removing water marks from the outside. What brand or type of cream did you use on yours to remove the watermarks?

  6. I used to have the same problem. Then I discovered that it isn’t really the bottle or the lid. It is the gasket inside the lid. This is true especially if she drinks things other than water. Nasty mold and mildew get built up on the gasket. The gasket is not easy to clean and putting the entire lid in dish washer or in white vinegar won’t work unless you pull the gasket out to clean. See this video below starting at the 30sec mark.

  7. Try to seat the ring seal as far in as possible. Then slowly twist the lid back onto the bottle. The motion will press the ring seal back into place. Might want to do it a few times to ensure proper alignment.

  8. Hi there, Crystal!

    Bar Keepers Friend Soft Cleanser is my go-to cleanser for any piece of stainless steel cookware I own (and I own plenty) – including the Hydro Flask.

    If you can’t find that particular brand for whatever reason, no worries – I’m pretty sure anything along those lines would work just as fine, too!

    Let me know how it goes!

  9. OMG! I can definitely relate, worst thing is that is thats their favorite bottle they dont care about the smell 🙁

    I actually had to do research till I came across the Hydrodryn stand. I bought one for all my Hydroflask and extra ones for them to have in their room. I realized that they need to completely be dried for at least a couple of hours, so now its a routine. My daughter washes her bottle and just places it on the Hydrodryn stand. The next day its smelly free!!

    All my bottles are moldy free, best thing ever. I have 7 Hydroflask (2) Black, red, yellow, (2) orange, and a gray one and they all have their stand.
    I swear I don’t deal anymore with the funny smells 🙂 Enjoy!!

  10. Hello, Jan!
    I haven’t had the chance to check out this product yet, and to be honest, I didn’t even know it was a thing. So, thank you for your tip!
    I’m afraid that buying a Hydro Flask is already an investment in itself – for most people, anyway – and that they’ll probably be looking for cheaper DIY solutions that virtually cost nothing.
    That said, I’m grateful that you shared this with us, and I’m sure others will appreciate having this nifty, little accessory, too.
    Love,
    Barbara
