What is the Best Way to Clean a Stainless Steel Bottle?

Big reusable water bottles can be difficult to clean, and in fact, many people still use disposable bottles for that very reason.  But it's really not that bad if you're prepared, and in the long run reusable bottles are way better for the environment as well as your wallet.
Picture
These are our recommended best practices and guidelines for cleaning your bottle, including:
  1. ​are they dishwasher safe,
  2. how to pick the right one,
  3. what accesories can make it easier,
  4. how often to clean it,
  5. what are some ways you can save money,
  6. and four things I would absolutely avoid doing.

Video: How to Clean Your Bottle

​​​​​​​​​We also cover this in a YouTube video if you'd prefer to watch the recap that way.

Part 1: Are Stainless Steel Bottles Dishwasher Safe?

Maybe you're wondering can you put stainless steel bottles in the dishwasher?  It's a simple question, but an unfortunately complicated answer.  ​Many bottles today are labeled as dishwasher safe, but in general I don't recommend it for three reasons.
Reason #1: It's not always clear which bottles are dishwasher safe
For example, regular Hydro Flasks ARE dishwasher safe, while their Trail Series bottles AREN'T.

Even more confusing, older regular Hydro Flasks with a thinner metal band below the lid are NOT dishwasher safe.

This varies from manufacturer to manufacturer, so it can be difficult to know unless you look up the manufacturer's recommendations (which is highly recommended).
Picture
Reason #2:  Dishwashers are more likely to damage your bottle
Even if the manufacturer says the bottle is dishwasher safe, cleaning it regularly this way can lead to more damage.

​
Some bottle brands like Owala even say their bottles are dishwasher safe, but they recommend hand-washing.  Any damage would most likely be cosmetic from your bottle banging into something else in the dishwasher and wouldn't make your bottle unusable, but cosmetic wear-and-tear is still not ideal.

Plus, smaller parts commonly found with lids are more likely to fall through the racks and potentially drop onto the heating element at the bottom of the dishwasher.
Picture
Reason #3: Handwashing isn't (usually) difficult
Yes, handwashing takes more time, but it's really not that bad once you get into the habit and have the right tools, like a brush kit and cleaning tablets.  And in most cases it's necessary for deep cleaning anyways (see below).

Part 2: Which Bottles are Easiest to Clean?

Not all bottles are created equal, and some are easier to clean than others.
Factor #1: Mouth Diameter
Narrow mouth bottles are more difficult to clean than their wide mouth counterparts.  With bottles like the 25oz S'well shown below, I can't fit my big bottle brush so I have to rely on cleaning tablets and soap baths.  But with others like a Stanley Quencher, you don't even really need a brush because you can fit your hand inside.

If keeping your bottle clean is a priority, there's no doubt wide mouth bottles are an easier choice (in addition to making it easier to add ice).
Picture
Factor #2: Lid Type
A good rule-of-thumb is that chug-style lids and the most basic lids (twist all th way on-and-off) are easier to clean than straw lids and sip lids.

​
Using YETI's lids as examples:
Basic Lids
These are super-simple, so cleaning them is pretty straightforward.
Picture
Chug Lids
They're a little more complex than basic lids, but still pretty simple and easy to clean (usually).
Picture
Sip Lids
These lids are typically used with smaller bottles for coffee or tea, and they're designed to restrict flow.  Often times they have smaller parts and inner pathways for your drink compared to chug lids, which makes cleaning more complicated (YETI's isn't actually that bad though).
Picture
Straw Lids
Straw lids are traditionally the worst for cleaning.  They add a straw, which requires another brush.  And flip-up spouts like this one have a seal underneath that can be difficult to get to (sometimes it's not possible without damaging the lid).
Picture
Factor #3: Pull Tabs
Also, consider whether the seals have pull tabs that make them easier to remove.  It's such a simple addition and we're always surprised more bottles don't do this.

Unfortunately, bottles that have this feature don't seem to advertise it much, but two options I know that do include Owala (just their spout seal, but not the one between the lid and the bottle) and Takeya Actives (both the spout seal AND the lid seal).

Part 3: What Accessories Help with Cleaning Bottles?

Fortunately the main things you'll need are easy and cheap: warm, soapy water and a sponge.

Beyond that, there are two accessories I almost always recommend getting with bottles like these.  I mentioned them earlier, but I'll add them here again because I really do think they are great investments and are important to keep your bottle in tip-top (and safe) condition.

Money Saving Tip:
​Consider buying denture or retainer tablets like these.  ​I've seen a bunch of people recommend this on my YouTube channel, and though I haven't tried it personally, the ingredients look very similar.  And they're A LOT less expensive per tablet than Bottle Bright.

​I personally stick with Bottle Bright because I feel comfortable with the company (instead of an Amazon store brand I'm not familiar with), and they're really not that expensive in the grand scheme if you're just using them once per month, which leads into...

Part 4: How Often Should You Clean Your Bottle?

Having and easy-to-clean bottle and the best accessories doesn't matter if you don't clean your bottle.

To prevent bacteria, grime, and mold from building up, you need to stay on top of your cleaning habits.  Here is our recommende schedule.
Daily
​For every day use, it's more about preventing stagant water by pouring out any water that's been sitting for awhile, like overnight or especially if it's been in a hot car.  Then replace it with clean, fresh water.
Weekly
Every few days (or at least once per week) is a quick clean. Use warm soapy water and a bottle brush to scrub everywhere you can reach.  Then wash it out and let it dry overnight.
Monthly
About once per month, do a deep clean.  Take out all the seals and gaskets and wash them with warm soapy water.  Drop in a Bottle Bright tablet, which can help remove any buildup like hard water residue that the brush couldn't easily reach (this also includes soaking the lid in a bowl with a Bottle Bright tablet or soap).
Keep up with this cleaning schedule, and you should be fine and will keep your bottle in great (and safe) condition.  Just don't be afraid to adjust this schedule as-needed.  For example, if you drink from a questionable water source when traveling, then give it a good wash after.  Or if you notice stains or smells from coffee, go ahead and use a Bottle Bright tablet early.

When in doubt, clean it out.

Part 5: 4 Mistakes I'd Avoid with Cleaning Bottles

If you've been paying attention, I've already mentioned the three things I'd avoid doing:
  1. ​Buying a narrow mouth lid
  2. Avoid straw lids (with some notable exceptions like Owala, Hydro Flask's Flex Straw, and Stanley's ProTour)
  3. Avoid using the dishwasher

But the fourth is very important.

​#4: Whatever you do, don't use bleach to clean your stainless steel bottle.
Yes, bleach would clean your bottle, and it's probably not a huge deal in very dilute concentrations.  But it's also very toxic so it's risky if you don't wash it all out by mistake.

And for stainless steel in particular, it can damage the material and lead to potential corrosion or pitting in the steel.

​Just keep up with your cleaning schedule, use Bottle Bright or denture tablets, and you should be fine.

Hope this helps, and happy hydrating!
