Picture of 5 Ways to Clean a Funky Water Bottle
Here are 5 effective ways to get funky smells and odors out of your Klean Kanteen, or any other water bottle for that matter.

Klean Kanteen has a website that covers these methods - some of the suggested tactics work better than others.  Check out the following methods and learn which ones work best.

Step 1: Take me to funky town

Funky water bottles can happen any time you put anything besides water into them.  The equation for the perfect funky water bottle storm is something like this (+/- a few variables):

juice and or coffee + hot car + time = FUNK 

In the image below we left this insulated Klean Kanteen in the car for a few days with tea in it.  When we opened it up there was mold everywhere growing on not only the tea bag, but the walls of the water bottle themselves.

Step 2: Wash with bottle brush

We're specifically not going to cover simply washing the bottle - I'm pretty sure that everyone can figure that one out without an Instructable. 

First up - wash the bottle using a bottle brush with hot water and soap.

The bottle brush physically removes the funk from the water bottle with scrubbing action.

Step 3: Wash in dishwasher

Picture of Wash in dishwasher
Stainless steel water bottles are dishwasher safe.  Put the water bottle into the dishwasher for a full "hot" cycle.  The high temps and strong(er) dishwasher detergent may result in success.

If you've still got funk, read on.

Step 4: Overnight boiling water soak

Picture of Overnight boiling water soak
If the dishwasher didn't work, or say you don't even have a dishwasher (like me), pour boiling water into the bottle and let it sit overnight.  

At the end of the soak, add soap, wash vigorously and reassess.

Step 5: Baking soda and water soak

Picture of Baking soda and water soak
Another method that works really well is to add one or two heaping teaspoons of baking soda and warm water into the water bottle and let that soak for a few hours.  

After the soak wash vigorously with soap and water and reassess.

Vinegar isn't a smart thing to to put into a metal can, its an acid. Acid + metal = salt, not good when you want metal to stay metal.
I've found that with clear water bottles (that arent UV-proof i suppose), I just stick them in the sunlight for a day or two, mind you, they get funky again pretty quick, but you get what you pay for.
Vinegar is fine for stainless steel. Nothing bad will happen overnight.
I wouldn't bet on it, the cheapy "stainless" bottles use 400 series stainless, not the much better 316 "food grade". 400 is considerably less corrosion resistant.
Vinegar is not a strong acid and even 316 stainless will take the treatment. Have you had experience of problems with corrosion with stainless? Probably not.
Yes, frequently, especially in the presence of chlorides. I often use monel
What is "Monel"?
A trademarked alloy of metal. http://en.wikipedia.org/wiki/Monel

Just to be on the safe side, I usually buy my water bottles out of Hastelloy X.

Thanks for the link!
Highly corrosion resistant metal, its classed as a nickel alloy.
I've used vinegar many times in my $11 Meijer purchased stainless steel thermos and never had a problem.
This sub-chat started because not all stainlesses are as stainless and acid resistant as others. Even specific steels are resistant to one acid, but attacked by another. In my work, I sometimes work with nuclear quality "NAG" stainless - Nitric acid grade- a special that resists attack by nitric acid, for example.

That's pretty interesting. From the Klean Kanteen website:

> Your Klean Kanteen is food-grade stainless steel, the same stuff they use in the dairy and food industry.

So the KK's should be fine. However, there are *tons* of similar looking knock offs, and I wouldn't bet on most of them using the nicer grades of metals.
i think you can wash it with vinegar followed by rinsing but not soaked for extended periods. even surgical instruments(ie surgical stainless steel) needs special cleaning methods, as it can pit and corrode.

ESSENCE OF GRAPEFRUIT SEEDS IS A BIOLOGICAL EATER OF BACTERIA AND IS A NATURAL PRODUCT EATING A NATURAL PEST IN YOUR WATER BOTTLE. NO NASTY CHEMICALS INVOLVED. A MINUTE QUANTITY DISSOLVED IN WATER LEFT TO SOAK FOR A FEW HOURS CLEANS UP THE BOTTLE BUT WILL NEED A GOOD RINSE OUT AS THE GRAPEFRUIT TASTE LINGERS !

Best i have found for even the most funky of funky containers.......Potassium permanganate, aka condys crystals. I'll tone down the talk, but, Its an oxidiser, the smelly compounds are all organic compounds (ie have carbon), so they don't get washed out, they get destroyed.
ooohlaa paliaspip4 months ago

where would one purchase PP crystals?

paliaspip ooohlaa4 months ago

Good question.. A couple a different places, 1) You can buy it at a Chemist (pharmacist), generally only a very small amount for $10-$20. or 2) you can buy it at animal produce stores, where you buy feed for chickens or spray for cows. It is used in cook water as a de-wormer. It is also known as condies crystals.

Not familiar with that brand. I use Hydroflask. No problem with those except the inside of the top is hard to clean. I periodically replace the top.

I've used denture tablets and baking soda before and they work well, but if I need something a bit abrasive I drop a handful of dry rice in the bottle with some soapy water, give it a good shake, rinse and repeat. On another issue, most aluminium water bottles (I have a couple of cheap ones myself) are lined with a kind of plastic liner. Adding anything acidic like fruit juice for any length of time can start to break down this lining causing the bottle to start to corrode.

I use denture tablets as well. Store brand are much cheaper than the branded water bottle/reservoir cleaning tablets. Fill all the way to the top with warm/hot water. Screw on the cap with the mouth piece open. As the tablet effervesces it will bubble out the mouth piece and clean that as well. Also, I don't use plastic bottles, only metal.

I must admit, I've always used metal bottles in the past, but recently I've been switching over to Nalgene bottles as I've been finding that the stoppers on metal bottles have been increasingly prone to leaking. For instance I recently bought a couple of new Snugpak bottles and had to send one back due to the stopper jumping it's thread each time you tried to tighten it up. The replacement sent had the exact same fault. I'd have been less disappointed if they were cheap bottles, but they weren't that much cheaper than the Nalgene bottles.

If you warm up the vinegar first in the microwave and then add to the container to be cleaned, it works better. Chemical reactions work better when the temperature is higher. Something to do with Charles and Boyles Laws if I remember high school chemistry from 50+ years ago.

It is not Charles, neither Boyle's laws... it is called the "10 C rule", and it tells that for every ten Celsius degrees in temperature raise, the speed of most chemical reactions is roughly doubled. And it hold true in most cases, even with organic reactions like those catalyzed by enzimes! Amclaussen.

I use water from the Glacier machines for .30 a gallon here in FL. I use old glass water or wine bottles and keep them out of the sun because algae will grow. I have been doing this for several years and have only twice gotten algae funk caused by leaving too long in the light. My concern is how clean is Glacier water machine process, does anyone know? I know this is tangential question so OK if you don't reply, just been trying to find this out for a while now.

Children's bottle cleaner and boiling water, leave for a few minutes and the scum floats to the surface. Household bleach and boiling water also works but only a drip of bleach.

I drink iced tea all day from metal water bottles. Even with rinsing between refills and brushing with a bottle brush they end up a little smelly and stained. I take all of my bottles once a month and fill them with 50-50 white vinegar and water. I place them in a large stock pot, fill it with water about half way up the outside of the bottles and bring it to a gentle boil for about five minutes. Let them cool and rinse them out well and all the stain and smell is gone. If you boil them too long it may loosen paint or finishes on the outside of your bottle so do it at your own risk.

HOT water and a little bit of caustic soda - sodium hydroxide, a teeny amount, slowly sprinkled in...

And a good long soak for a couple of days.

Eats everything out of the bottles.

I agree on the denture cleaner. Sometimes you can get a little bottle of crystals for less than an equivalent of tablets.

Long, long ago, I worked at a Wendy's in the Catskills. The one useful thing I left that place with (besides the funky hat!) was how they cleaned glass coffee pots: throw ice, salt, and a chopped up lemon in the pot, swirl 'til partly-melted, then rinse. Abrasives and acid = awesome! And no one ever complained about soapy or vinegary coffee. Not even salty lemon coffee!

If I don't have a bottle brush I use a hand full of pebbles with hot soapy water as a scrubber.

I use warm water & bleach like some other a couple other people said too. It's the safest way and will remove odor too.

The denture claning tablets do a great job,it's a trick I learned fom a truck stop waitress over 20 years ago and I've used it on my (same bottle I still use) StanleyThermos ever since.

AS far as stainless steel rusting the 400 series stainless will rust much qoicker than 300 series due to the 400 having much less nickel in it.

White vinegar will remove water spots from stainless..............

If you do not have vinegar, some real lemon, or other citrus juice will rip out most of the stuff stuck on the sides. Another thing I have used is CLR (or dip-it coffee pot cleaner) since the lime deposits from use give the funk a good place to hide.

I drop in a small handful of ice cubes and a little cleanser, such as Comet or Ajax, then swirl it all around to scrub the inside clean, and rinse thouroughly. This also works great for stained coffee carafes.

Another great method that got the coffee stains out of my steel thermos was to use an effervescent denture cleaning tablet. My wife uses them for her retainer, I figured something that can clean something that goes in your mouth must be pretty safe. The stains came right off too!!!

vinegar and water over night

I agree with henmar. A capful of bleach, fill the rest with soapy water. I let bottle sit for many hours. Always gets rid of mold, smells, science experiments that started growing in a forgotten bottle! Rinse well. Bleach is used in drinking wells around the world...no worries about health dangers if used in small quantities and rinsed!
I had a bunch of "funky" water bottles... now I dont

I use a Milton solution which was commonly used here for soaking and sterilising babies' bottles. It is a chlorine base thing. Comes in liquid or tablet form. The tablets are also great for sterilising water for drinking (1 tablet for 32 litres)
