I have quite a few stainless steel water bottles - "Klean kanteens" and others. If I put clean - either tap or bottled - water into these in the car, do you think the water would stay fresh for a reasonably long time even if it gets hot?
At the moment I just throw in a couple of 1.5 lt bottles of purchased water which I leave in there, and we all take a drinking bottle or two as we leave the house anyway, but I don't like leaving a plastic bottle of water in the car, potentially getting hot, for long. Then I forget to change it and end up not wanting to use it. So if I put the water into stainless steal, can I leave it there a lot longer? Would you suggest anything, like washing the bottles with Milton first perhaps, to extend the time?

I personally would see no issue with stainless steel containers getting hot. I would use tap water as its already chlorinated and treated.
If you're really concerned and we're talking really long term storage, you could auto-clave the bottles before filling. I personally wouldnt bother.
Open the bottles to get some fresh air in them and give them a good shake before drinking to get them tasting fresher but stainless is a wonderful material and water doesnt go bad unless theres somthing in there...

Plastic bottles wouldn't be too bad as long they stay out of sunlight and you replace every now and then. I use mine on the garden when replacing it.
Stainless steel bottles would also be good cause you can even use them for heating up on a fire.

I have several of the Klean Kanteens, all different sorts. Be sure to wash them a few times first, I think they must wash them out with bleach as several of mine had a strong smell/taste of bleach for the first few times I used them.

Then I forget to change it and end up not wanting to use it. So if I put the water into stainless steal, can I leave it there a lot longer? Would you suggest anything, like washing the bottles with Milton first perhaps, to extend the time? I have been taking water samples and analyzing water on and off for many decades. The main issues with water is parasites (bacteria), high metal or contamination, and algae. Chlorine kills the bugs as well as heating to about 66 C, that why they say take water to a boil and cool down. The boil is to be sure you got to the 66 C. Getting the container hot is good, that is how one pasteurizes water it kills all the bugs. Clear plastic allows light to get in and that can accelerate algae growth. If the water is contaminated with metal or some pollutant then no matter what container you use it will be a problem. I would fill the SS bottles with council tap water full to the top and tap all the bubble out of it like there is a meniscus, then screw the lid on and you have the best chance of water preservation, should last years. Leaving it in the sun is no real problem, not nice to drink hot water. If you are concerned about bacteria then boil the water prior to putting it into the SS container. I would say SS is the best type of container to use, needs to be air tight. For large like +10l containers one can put a half tee spoon of bleach in the water, then cover with black bag to prevent sunlight entering. |

Thanks for the replies. Confirmed what I'd been thinking.
We've had the klean kanteens for many years - I ordered a couple of boxes of them shared with friends from overseas before you could get them in Aus - so no fear of any residue left in them from the factory! I have a bigger problem with possible bacteria from previous use. And for keeping in the car I'm not after terribly long term - just a few months - as we use them for refilling our water bottles on outings anyway, but sometimes we don't use it for a while so it can sit there for a few months. Just with the summer heat I was going to change from plastic (which I just do because it's easy - buy a bottle and leave it in there) to stainless steel and was checking for any issues I hadn't thought of. I think I'll clean out the bottles with boiling water and perhaps even fill them with boiling water. They should be right for a few months.
(Longer term storage at home I store cheap purchased water and just use and replace - and I have filters and a creek if needed for even longer term.)

I wouldn't worry too much with tap water in stainless. I work in the lab of a food manufacturer and water testing is one of thing we do. At least in the city, water is pretty clean contrary to popular belief. These is pretty much nothing to support growth of anything. Even basic robust life forms need some form of available nitrogen source and energy to multiply. Boiling helps but more a peace of mind than anything else. If you must, distilled water will last as long as the containers.
With Stainless bottles, I worry about the seal failing more than anything else.... plastic/rubber seals, whatever, don't worry too much neither, anything we read about that could be harmful is only long term, unless you cart around a few months worth, you body can deal with what is in the water....
