Anybody out there know about storing water bottles? I'm talking about the .5 or 1 or 1.5 liter water bottles you'd buy at 7/11 or wherever. I often re use water bottles, I'll grab one that has been sitting in my cupboard for possibly an extended period of time, weeks or possibly even months. Normally there are a few water bottles that just get put in the cupboard and left there because they're handy to take to the gym or wherever. There would generally be a bit of water left in the bottle when they're put in the cupboard so with the heat in BKK, I'm wondering if bacteria could be generated that might cause a health problem.

I'm not referring to bottles that ever held anything other than water.

Thanks

if you are doing it and it's fine - than no problem.

I do buy 25 litre bottles for 20 baht and than keep a few littres in plastuc bottles in the fridge, ready to go

Sell the old ones and but new ones for 10 baht or so.

Nearly as tight as my grandmother photo below.

we re use our bottles all the time i buy the big 25 litre bottles for 10 baht then let the kids syphon it into the smaller bottles , to answer your op as long as the lid has been on the bottle or if unsure just give them a rinse out , i cant see it being a problem

My old water bottles go in the local rubbish bin. They don't stay there long though - removed by the local bin scavengers who sell the plastic for 20 baht/kilo and cans for 30 baht/kilo.

if unsure just give them a rinse out , i cant see it being a problem

I assume you mean rinse them out with a bit of drinking water - rather than tap water.

If you drink straight from the bottle you might want to swipe the mouth of the bottle and inside the lid too.

I reuse them all the time, what I do, however, is when I am done with them, I rinse them out well and leave them upside down at least overnight and then put them in the cupboard (or refill and into the fridge). I wouldn't leave any water in them, but if I did, I would rinse them well--and tapwater is perfectly safe to rinse them with--at least in the cities.

A second consideration is that there is some deterioration in the plastic over time. Other posters may be more knowledgeable about this and can comment. I try to rotate them out of the system every few months or so. As I get a new bottle, I get rid of an older one. To make sure I know which ones are the oldest, I use rubber bands on them--one month I'll put red rubber bands on them and the next month the brown ones--that way I know which ones should be tossed.

I also keep a row of frozen bottles in the freezer. I then put them in a cooler when I go shopping or am going to be out of town. Be sure and squeeze the bottles before freezing, as the ice expands.
