My Hydro Flask is a durable and aesthetically pleasing water bottle that I recently purchased. This purchase came with a hefty sticker price, but I figured the investment in my health would be worth it. However, after about a month of use, I noticed minor dents on the mouthpiece.
The good news is that these dents are not affecting the integrity or function of my hydro flask – but they’re displeasing to look at and slightly embarrassing when sharing with friends.
The bad news is that there doesn’t appear to be any easy way to remove these dents from your hydro flask – especially if you don’t want to risk ruining your investment by applying too much pressure or heat (because these are tricky buggers). In this article, I’ve found six ways to easily remove your hydro flask dent so that you can use your hydro flask without shame!
Method #1: Freeze It!
There are several reasons why you may have dents on the mouthpiece of your Hydro Flask or any other water bottle, for that matter. For example: if you put the mouthpiece in the freezer and then put hot food or liquid in it, it will be pushed out as the liquid cools down and contracts.
This is what happened to my Hydro Flask – I accidentally left a spoon inside (oops!), and as soon as cool water was added, the spoon pushed itself into the bottle with a bang.
The good news is you can use the freezer to your advantage in this situation – leave the mouthpiece in there for a couple of hours, and then try twisting it back into place.
The cold temperature will contract your flask (and any resulting dents), and you’ll be able to remove it quickly. I did this method and successfully pulled 2 out of my three dents using this method alone!
Method #2: Use Rubbing Al-cohol
High school students worldwide have successfully removed dents from their water bottles without heat or pressure by taking a bottle of rubbing Al-cohol, adding a little soap, and then gently swishing it around.
The Al-cohol will contract the metal, making it much easier to remove the dent. You should be very gentle when you do this – hold the mouthpiece straight up, swish gently back and forth, and then set it down gently before the dent has time to re-appear.
Method #3: Use a Dish Soap Solution
All of the above methods were tested using cold water, but if you’re looking for a solution that uses warm/hot water instead of cold, try this combination instead. All you need is a “Delicate” dish soap and a microwave – just add the soap to the bowl and microwave for 30 seconds, then swirl around and disburse. This will help contract the metal of your hydro flask, making it easy to remove.
Method #4: Use Gently Exert Pressure
In the past, I’ve found that by gently exerting pressure with my thumb on either side of the dent, it will make it easier to remove. This method yielded great results for me, but be careful – using too much force may damage your hydro flask.
Method #5: Use a Toothbrush to Remove the Dent
This is an easy and safe way to remove dings from your hydro flask – all you need is a non-abrasive toothbrush. The diameter of the bristles should be as big or more significant than the dent itself, and you’ll want to rub them on the dent until it disappears gently. This method removed both small and large dents on my hydro flask.
Method #6: Purchase a Dent Puller Tool
There’s a unique tool available at many hardware stores that will help you remove dents from your water bottle – this tool has been designed for just that purpose. Below is a link to the dent puller tool on amazon –

If you have specialist skills and tools, there are also methods available that use heat – place your hydro flask in a container of hot water (be careful of sharp edges), then use a hair dryer or heat gun to warm up the metal. I’ve found it challenging to get the timing right with this method, so I’d recommend using one of the other five methods first before attempting this solution.
Hydro Flask Repair
A few days ago, my hydro flask broke. I panicked and started researching the next step of the process. As I scrolled through countless pages on Google, I went from a level of panic that was paralyzing to a group of determination and purpose.
My fix would not be convenient, but I could do it myself with some help from this article and whatever resources were available to me.
I will try to cover the most common points of failure with this guide, and hopefully, this can help you, whether you’ve never tried fixing your hydro flask or have broken one before.
The Hydro Flask Repair Process – Step by Step (Theoretical)
- STEP 1: Purchase a new hydro flask if you don’t already have one.
If you’re reading this, I assume your hydro flask broke (cracked, banged up, smashed), and you don’t have a spare or second one. At the very least, it probably means that your current bottle got damaged in the first place.
- STEP 2: Investigate the Hydro Flask Design
I’ll assume you’ve done a little reading on hydro flask design so you have an idea of its parts before I get into the process itself. Here are a couple of crucial pieces to the invention; if they’re not there, you will have problems.
1. Metal Mouth Piece on top that holds water or drink mix sealed under the plastic cap.
2. Cap to seal the mouthpiece from outside water or drink mix access only
3. Cap to seal the mouthpiece from outside water or drink mix access only
4. Straw for drinking
5. Lid with a hole for the straw to drink out of
6. Threads on top of the cap that screws into the mouthpiece
7. Threads on the bottom of the body that screws into the lid/cap
And this is what it looks like:
STEP 3: Take Apart Your Hydro Flask
Find a clean and safe spot to work on your hydro flask where any pieces (liquid and solid) will not end up all over your car, floor, wall, dog, cat, etc. This can be the garage, backyard, and, in my case, the toilet (lol).
Find a workspace to keep everything you’ll need there. I used a small towel folded into triangles and taped with masking tape to help keep everything from leaking.
I needed a large screwdriver (flat tip), pliers for small screws, needle nose pliers for removing parts of the cap, and some tweezers for when something got stuck on the straw/mouthpiece.
Here are my tools:
STEP 4: Decide which pieces you will replace and take them out.
I knew I would replace the metal mouthpiece and cap because that was where my hydro flask had broken in the first place.
STEP 5: How to detach the old part from the rest of your hydro flask:
Here are my tools again. As you can see, I’m using pliers here to twist off the metal mouthpiece from the plastic cap. This will keep it from getting damaged further and make positive progress on repairs should you need to take some more apart later.
STEP 6: How to disassemble/remove a cap/mouthpiece:
This is where things get more technical and detailed, depending on how easily you find these parts to be removed. Here are my tools. In this picture, I have pliers to keep the cap attached to the hydro flask and tweezers to remove anything stuck there.
Once you know where the threads are and which direction they’re in, you can use a screwdriver or any other tool to start prying it apart. Typically, this will split or scratch the plastic cap since it is not well made. So be careful. I used my pliers and flat screwdriver tip to twist from side to side at first until I could feel resistance from inside of the semi-circle area of the cap:
STEP 7: How to remove a straw:
This is extremely simple. Use your pliers and clamp down on the straw to twist it off. Once it is loosened up, use your pliers to pull it upwards. Wiggle a bit, and you should be able to take it out.
STEP 8: How to remove a mouthpiece:
This is where things can get messy if you’re not prepared. This was the most challenging part for me, but I learned how to remove the mouthpiece from a hydro flask after seeing my mom do it on one of my sisters’ broken hydro flasks.
- i) Grab the mouthpiece and twist it upwards. This will push them apart, and you can start to use your pliers to pry them upward a bit.
- ii) Once the cap is loose, don’t be afraid to wiggle it up and down. This helped me get it off more quickly than twisting from side to side.
- iii) After taking out one bottle cap/mouthpiece, I could find two more caps just behind it (on both sides of the mouthpiece). Just twist them off with your pliers as well.
STEP 9: How to remove a metal cap/mouthpiece:
This is where I found that all of my hydro flask parts, except for the one that holds the drink mix, are held on by threads. So this step requires some more technical know-how and is harder to do than the rest.
- i) Grab your metal mouthpiece and twist upwards from the bottom (see picture below). This will pull the metal cap up and off. If you do this wrongly, it will scratch your metal bottle because it is just a very tiny piece of metal.
- ii) Once the mouthpiece is off, you can see the plastic threads that are holding on the metal body. Use your needle nose pliers or a screwdriver to pry them out by pulling to the side. This CAN scratch your metal flask if you’re not careful, so DO NOT USE FORCE.
- iii) You’ll have to repeat this process for ALL of the threads on all sides of your bottle until you remove all of these pieces from your hydro flask.
STEP 10: How to reassemble everything together:
This was probably one of my favorite steps because it was highly gratifying =). I reused the caps from the other bottle I had to use, but you can use all new ones if you want. Here’s how to put it all back together:
- i) Place the metal cap on top of the plastic cap and twist them together (see picture below).
- ii) Screw in the threads on top of your hydro flask holding the lid.
- iii) Insert the straw and screw in your lid. This is also where I added some anti-corrosive on my straw because parts of it were coming off as well.
STEP 11: Fill up with water and see if it works:
I filled up my replacement hydro flask with water (great test). You can see that I was successful. There are no leaks, and everything is water-tight =). My hydro flask is new again =)
Now that you’re done look at it and see what you can do to improve it. I would love to hear your feedback below!
Do dents affect Hydro Flask?
Dents can affect the performance of the Hydro Flask. They can cause the lid to leak and the vacuum insulation to break. Dents are a common thing that happens with Hydro Flask bottles and lids. This is because it is made from stainless steel, which is very vulnerable to dents and scratches.
Just as you shouldn’t put your Hydro Flask on a rough surface, you shouldn’t put it in your bag too tightly or in a place where sharp objects could damage the lid or cause leaks.
Can I return my Hydro Flask if it dents?
If the bottle has been damaged, you may be able to return it within its warranty period.
Yes! You can return your Hydro Flask within its warranty period if it has not been significantly damaged or used beyond its intended use by the manufacturer.
How do you fix a deformed Hydro Flask?
The first step is to remove any visible liquid from the bottle. If no fluid is present, it’s time to try and repair it. The best way to fix a deformed Hydro Flask is by using a vacuum cleaner with a hose attachment.
You can use this method to get rid of any dirt and debris that may have collected inside the bottle from point A to point B.
Step 2: Use a sharp knife to cut the bottle along its seam. Place the Hydro Flask on its side to get better access to it. Be careful not to cut your fingers; use the knife handle rather than your finger to make sure the blade doesn’t slip out of your control.
Step 3: Using a pair of pliers pull on the end of the bottle where it’s deformed to stretch it back and seal it back together. The Hydro Flask will naturally start to fill with air as you do so and will also widen a bit, which can help seal your cut.
My hydro flask took about an hour or 2 for me to repair. I wasn’t in a rush, so I took my time. Then I’ve had it for about 3-4 weeks (following college classes), and there have been no problems with it.
I’m pretty happy with the results because my hydro flask looks new and functions just as well as before. So if you take your time and research online, I think you should be fine. I’d love to hear any other comments about your hydro flask repairs or on different ones.
