To help keep your Hydro Flask bottle clean you'll want to invest in a good bottle brush. The last thing you want is for your expensive Hydro Flask to get moldy because you didn't clean it properly.
If you're like me you'll want something that makes it quick and easy to clean your Hydro Flask. But also something durable enough to last a long time and strong enough to clean out tough stains and gunk from that time you left your Hydro Flask for a month without cleaning it.
So I've had a bit of a search over the web and below I've highlighted specifically bottle brushes that I believe are perfectly suited to Hydro Flask and other stainless steel bottles.
Why You Need a Bottle Brush For Your Hydro Flask
Over time your Hydro Flask can collect a lot of dirt, grime and mold and it's important that you clean it on a regular basis.
Because Hydro Flask bottles are quite tall it can be difficult to reach the inside of the bottle with a regular sponge. The standard mouth bottles you can only fit a few fingers in and even the wide mouth bottles are too small to fit in your entire hand.
A bottle brush can go inside the bottle and get to the hard to reach places allowing you to scrub it clean and avoid any mold or grime build up.
You should be washing your Hydro Flask bottle on a regular basis in warm soapy water using a bottle brush to scrub the inside. Click here to learn exactly how to clean your Hydro Flask properly every time.
What to Look For In A Hydro Flask Brush
Hydro Flask bottles are tall and are made from 18/8 kitchen grade stainless steel which is a strong and durable material.
In order to clean it properly you'll need the right bottle brush. Here are some features you want to consider when choosing a Hydro Flask bottle brush.
Length
You need to make sure the bottle brush is going to be long enough to reach the bottom of your bottle.
Most Hydro Flask bottles are a similar height (see the Hydro Flask size chart) so you'll want your brush to be at least 10-11 inches in length in order to reach the bottom of almost any Hydro Flask Bottle.
Hard Enough Bristles
Some bottle brushes have extra soft bristles, and while this may be good for baby bottles it's not ideal for a stainless steel durable bottle like the Hydro Flask.
You're going to want a bottle brush with tougher and harder bristles than can firmly wash away any buildup your bottle may have.

Durability
An issue with cheap bottle brushes is that you use them just a couple of times and they go completely deformed and become useless.
Give your Hydro Flask will last you years (maybe even decades) you're going to want a bottle brush that you can use on a regular basis for a long period of time.
While the bottle brush is unlikely to outlast your Hydro Flask you still want it to last a decent amount of time.
Non-Slip Handle
Having a good rubber non-slip handle makes cleaning your Hydro Flask so much easier.
Often you need to apply pressure to give your bottle a good scrub so a non-slip handle makes it easier on your hands and wrist.
Small Cleaner For Your Lid/Straw
You may also want to get a smaller brush for your lid or straw (depending on what lid you have).
The lids can be one of the main areas hidden mold can build up so having a smaller brush to get into the hard-to-get grooves is extremely helpful.

Dishwasher Safe
While Hydro Flasks are not dishwasher safe I personally want a bottle brush that I can throw in the dishwasher every now and then to keep it clean and to sterilise it.

6. Philips AVENT Bottle Brush
Price:
I really like this style of bottle brush with the shorter bristles so you can scrub harder and get a better clean.
The curved brush head makes it easy to clean the bottle of your bottle and to get into the curves down the bottom.
The shaped end is also useful for cleaning out dirt and mold build up that can occur in the lids of our Hydro Flask bottles.
The major downside to this brush though however is the length. It's only 11 inches in length toal and while this is fine for the shorter Hydro Flasks it's not great for the taller ones.

CONS:
- Too short to fit in taller Hydro Flask bottles
