Knowing how to clean your hydro flask is important. Beyond just keeping it clean for regular use, you don’t want to accidentally use a clean it with something that could damage it.
In this guide, I’ll show you exactly how to clean it and what to avoid to ensure it stays functional and looking great.
How to clean a Hydro Flask by handwashing
The recommended way of cleaning it is by handwashing as mentioned by Hydro Flask themselves. If there is any build up from what you were drinking, you’ll want to have a bottle brush on hand – any kind will do. Personally, I like the ones that are longer so it’s easier to reach inside the bottle.
- First, you’ll want to have some white distilled vinegar on hand. Other cleaners you can use would be baking soda or a light dishwashing soap (that doesn’t have bleach)
- Do a light scrub with your brush and cleaner to cover the entirety of the inside of the bottle. Let it sit for five minutes.
- Rinse it well with warm water and leave out to dry. Repeat the process if any odor remains.
If you are wondering how to clean a hydro flask without bottle brush, you can do the above steps without the brush as well. Usually a good baking soda and water combination shaken vigorously will do the trick too.
Another question I see a lot is “How to clean a Hydro Flask with vinegar?” Follow these simple steps to do so:
- Fill your bottle up half way with water, then fill the remaining half with distilled white vinegar.
- Screw the cap on and give it a shake for about 10-30 seconds to mix it up.
- Let the Hydro Flask sit overnight.
- The next day, rinse it out and allow it to dry.
As you can see, simple and straightforward to get a squeaky clean Hydro Flask.
What to avoid when cleaning your Hydro Flask
People commonly ask if their Hydro Flask is dishwasher safe – the answer is unfortunately no. The reason being that a dishwasher actually gets hot enough that it can damage the bottle’s insulation as well as discolor the powder coat.
Wondering how to clean your Hydro Flask straw lid? The lid can be placed in the top rack, but I would hand wash it too just to avoid any possible problems.
Another common problem is using harsh cleaners like bleach or chlorine – both will rust the stainless steel, effectively ruining the bottle.
Why bother cleaning it?
Much like any bottle, damp dark spaces make for excellent spots for bacteria to grow. It’s not something unique to the Hydro Flask. That said, you’ll want to check and clean out the lid after using it to prevent any build up and getting rid of moisture.
Cleaning proactively will keep your bottle from getting really gross over time and ready to use at a moment’s notice.
In a worst case scenario, you can put the straw lid in the top rack of the dishwasher if it needs a deep cleaning.
Trust me, it’s not a great time when you’re ready to head out on a trip and you notice your bottle is filthy! Depending on how you’re cleaning it, it may take some time to get ready to go.
Other tips to keep your bottle in good condition
Aside from cleaning your bottle properly, there’s some other things to keep in mind to make sure it stays in great condition.
Firstly, freezing the bottle has no benefit because of the insulation. For colder water, you’ll want to put more ice cubes in it.
Secondly, don’t use your flask to boil water! Similar to the above, the insulation will prevent the water from actually warming up and will just mess up the exterior of the bottle.
Now you know how to clean your Hydro Flask
As you can see, it’s really not hard to keep a Hydro Flask clean. Keep it simple using non chemical cleaners, rinse, and repeat if necessary.
Like most cleaning, it’s better done proactively but if you didn’t – no worries! Stainless steel is pretty easy to handle.
