How to Clean a SodaStream Machine Including the Bottles

Soap bubble

Your brand new SodaStream machine just arrived and you’re getting ready to make your first homemade soda. You’re excited to start saving money and maintain your soda addiction without producing any more waste.

Before you start making your own soda, stop and make sure you know how to take proper care of your SodaStream machine. These machines are pretty durable but anything can break down. The bottles should also be cleaned properly on a regular basis to make sure you don’t end up mixing flavors by accident.

How to Clean a SodaStream

Luckily the SodaStream machine is actually pretty easy to clean. All you have to do is remove the CO2 canister and wipe the machine carefully with a soft, damp cloth. The water you use should be lukewarm. You shouldn’t need anything other than water to keep your SodaStream machine clean.

How to Clean SodaStream Bottles

How you clean the bottle depends on what kind of bottle your SodaStream machine came with. If you chose one of the models that uses glass carafes, you’re one of the lucky ones. The glass carafes are designed to be easily washed and they’re even dishwasher friendly.

If the model you chose came with plastic bottles you’re not so lucky. The SodaStream plastic bottles are designed to last for three years, but they aren’t dishwasher friendly. Since they’re shaped like normal pop bottles, they’re not easy to clean either.

If you’ve been using the bottle purely for sparkling water and you haven’t used it many times, you can probably get away with a blitz clean. Start by filling the bottle halfway with water and tip it out. Do this a couple times to make sure the bottle is thoroughly rinsed, then fill it 75% with water, close it, and shake it vigorously. Empty it again and rinse it one last time.

By now the water coming from your tap should be scalding hot. Rinse your bottle cap thoroughly and get back to making soda.

If you’ve been using the bottle for a while or you let it dry out with SodaStream residue still in the bottom, you’ll want to do a full clean. This is very similar to the blitz cleaning process but a little more intense and involves using dish soap.

To start, fill your bottle with hot, soapy water and pour it out. Fill it again and this time screw on the cap. Shake the bottle vigorously for a few minutes and pour most of the water out. You can scrub the bottle now if you really want to, but it should be fine if you shake the remainder of the soapy mixture around a bit more and pour it out.

You’ll want to make sure you rinse thoroughly with extremely hot water. Nobody likes soapy soda and too much soapy residue can even reduce the amount of fizz you’re able to put in your next drink.


The most difficult part of maintaining your SodaStream machine in perfect combination will probably be resisting the urge to carbonate everything but water. Cleaning the machine is extremely simple and while cleaning the BPA free plastic bottles isn’t quite as easy, it’s a fairly simple process that won’t take up much of your day.

    Can you suggest the best way to get rid of stains left behind in the soda stream bottles, especially after orange flavoured soda.

    • Julie

      Hey Noel! Your best best is try using a bit of lemon juice to remove stains. It can sometimes work better than soap because it’s more acidic. Avoid using bleach as it can damage the bottle.

  • Daniel

    It’s also a good idea to clean the grooves of the cap and bottle with a toothbrush. I find they inside of to be the dirtiest part, because it’s the hardest to clean (and your method won’t actually clean it).

    • Amy

      I have the same problem… the caps get gross! I feel lime i need to somehow remove the rubber ring on the inside of thecap to thoroughly clean under it but I haven’t been able to. Any advise?

      • hobo

        Use something pointy like a toothpick, being careful not to damage the gasket, and working on the inside edge (not the outside threaded edge), slip the toothpick under the seal, then work your way around, lifting the seal up. Eventually it will pop out easily.

        Then you can clean all the mould! Ick.

    • Dlee t

      The caps are dishwasher safe and that can get the mold that gets under the gasket and into the grooves.

      • Lynn

        The bottle lid gasket can be taken out by using a letter opener, be gentle and it will eventually come loose. Thing is mine came out and it was holding the most of the smell. Well cleaned and see what comes of it. Hate to buy new one as reviews are not as good as original.

  • Christy

    Hi Julie! We broke down and tried to carbonate white wine. Ugh, what a mess! Now I need to know if I can submerge it in water to get it really clean. Do you know if that will hurt it?

    • Julie

      Oh no! I’ve never tried submerging one before so I’m not sure what would happen. Since there aren’t any electrical components, my gut says it’s ok, but I can’t say for sure!

    • Stephane

      Hi Christy! We made the same mistake and I was wondering if you tried submerging it in water? Did it worked? Thanks!

    • Andy

      Haha! I did the same! Not a champagne maker!
      Insane mess

    • K

      Maybe next time just carbonate some water to add to the wine 🍷 It says right in the booklet to only carbonate water.

    • Karen

      Yes you can submerge it. I once tried to carbonate water that had fruit in it. I strained out the actual fruit but there was still some sugar or maybe a strawberry seed in it which was sucked back into the Soda Stream clogging the nozzle. The soda stream people said that sadly I would probably just have to junk it. But I decided to soak it in luke warm water instead– had nothing to lose at that point. It worked great.

      • I made the error of carbonating pomegranate-cranberry juice. Huge mistake, with more than half the fizzy juice going every which way. I made the added mistake of not immediately carbonating plain water to help clear the nozzle, which might have saved the day. Anyway, by the next day, the machine went through the motions, but no CO2 came out through the nozzle.

        There is an amazing lack of information on this problem anywhere on the web, and an even bigger lack for the Fizzi One Touch, which is the model I have. Okay, so this is what I did: I took out the gas canister and unplugged the machine to avoid any possibilities of disaster (probably unnecessary, but not a big deal and it prevented me from inadvertently doing anything else stupid). I then adapted Karen’s advice, above, to this machine, which should not be submerged since it has an electrical component.

        What I did was fill a bottle almost to the top with water, to submerge as much of the nozzle as possible, and then put it in the machine and let it sit overnight. My hope was that the water would clear out whatever residual juice was blocking the nozzle. Next morning I took out the bottle, poured out enough water to get to the fill line, put it in the machine (into which I had reinstalled the gas canister and plugged in), and voila! — it worked just like new. Whew, what a relief!

        There is still some residual juice stuck up in the mechanism, but I’m inclined to let sleeping juice lie and just be glad I was able to salvage the machine. Meanwhile, no more carbonating anything but water for me! Hope that helps some out there in SodaStreamLand.

    Hi, I recently purchased a sodastream at Goodwill for $4 (go me!).

    How do I remove all of the previous owner(s)’ mouth germs from the plastic soda stream bottle?

    Is there anything else I should watch out for with a pre-owned soda stream machine?

    • Julie

      Great find! Aside from dish soap, you could try cleaning it with a hot water and vinegar solution. Vinegar is very good at removing stains and odors.

    • Rebecca

      I bought my soda stream off of OfferUp. I cleaned the machine with Clorox wipes and water. It came with a couple bottles, but I played it safe and bought new bottles.

  • Luc

    At the nozzle where the carbon comes out of, is a little clogged. Is there a way to remove and clean inside that nozzle cause its barely coming through?

  • Cameron Jenkins

    I’ve gotten a 10lb tank with an adapter I’m having trouble I push down the button I got a good rush of co2 but it Peters out to soon is there a ajustment to it

  • Michael Malin

    The best bottle cleaning solution is…Vinegar! Fill bottles 1/2 full with vinegar then warm tap water to 2/3 full, close and shake vigorously. Let stand overnight. Then thoroughly rinse with warm water. Continue as usual. Most store vinegar is 5% acetic acid which is more than potent enough to remove all residues and funky tastes but harmless to gasket seal in cap. Have 6 bottles. Use two full ones each day for 5 years. Yeah, this works!

  • Diana

    I have three soda stream bottles and two machines! We love it!! It has been about two years now we have been using the machines and bottles. I have rinsed the bottles each time I have used them….with warms soapy water as recommended. Lately, I have noticed a foul smell coming from the bottle lids. As hard as I have tried, I can not seem to remove the plastic o-ring to clean under it. Should I just do away with the bottles? Or can I purchase new bottle lids?

  • Carilyn

    The inside of my plastic bottles has a cloudy residue that doesn’t come off with soapy water. Any ideas?

  • Robert

    I’m really not clear on whether you can carbonate other than just plain water. The directions / instructions aren’t clear or I am missing something. If I put essential oils in can I do it before or after carbonation?

    • Julie

      Officially you shouldn’t carbonate anything other than plain water with a SodaStream (but sometimes people do it anyway). If you are adding essential oils, I would do it after you carbonate the water.

  • Mark

    Have you guys ever tried cleaning the black rubber washer around the nozzle? (the part that encloses your bottle opening when you carbonate) I just tried wiping it with a paper towel and is a dark black residue that comes off! No matter how many times I wipe, it’s still there. It’s like it part of the rubber that just keeps coming off.

    I’m concerned about this and am wondering if it’s nomal

  • Michelle

    How do you get mold out of the bottom? I bought a bottle brush but bristles were too soft. Tried vinegar and baking soda and various other things, no go.

    • Jaed

      I would try some rice and hot water i just did this and it removed the mould from the whole bottle besides the cap

    • Julie

      Michelle, Take no chances with mold. Buy a new bottle. And in the future, carbonate only water and let the bottle completely dry out with cap off after rinsing it with warm water.

  • john fournier

    you can carbonate white wine with a manual push button machine– wine has to be cold–do not fill bottle to top-leave 2inches– use only plastic bottles– push button for only a second then stop –do this about 10 times let sit–then slowly remove bottle—

  • Dan

    I too have the mold (I’m assuming it’s mold. It’s black) at the top of the nozzle, inside the mechanism. I tried leaving it overnight in a slight solution of bleach. No good. I’ll try vinegar but based on other comments I’m not optimistic. Just the thought of that stuff at the top of the nozzle makes me not to want to use sodastream (which I love BTW).

  • Rose Hollands

    Can you remove a cylinder safely before it is empty. Machine not working but cylinder is full

  • Karen

    My soda stream bottles have developed a strong chlorine odor. I only carbonate filtered water in them. I wash them in between by either rinsing or with a little dish soap and warm water. (It says not to use hot water on the bottle) So I got rid of the bottles that were past their expiration date and bought new ones. I have the same problem with the new bottles. I can’t figure it out. Our other reusable water bottles (the ones we just put filtered water and ice in) don’t smell like that. Has anyone else had this issue?

  • Barbara

    I am also wondering how to get rid of mold/mildew from the caps, under the rings, in the bottles and around the screwtops. thanks.

  • Amy Nelson

    Mildew smell every time I use it after a hot and humid month and two days of no use because I ran out of air! GROSS! Can’t see how to take it apart to clean inside, but it’s definitely got mold inside. Safe to run vinegar????

  • James Moore

    One can scrub and polish the inner surface by adding a bunch of salt to an empty bottle and shaking vigorously.
