The plastic in water bottles does deteriorate with time. There is some evidence that the by-products of the deterioration are carcinogenic. Me, I replace my bottles when I break them, when they start to taste funny, or when they just get too ugly for me.

Bottles are cheap enough. If you are concerned about yours, just replace them.

what kind of plastic bottle are you using? there is evidence that say's the chemicals leak into your liquids in many plastic bottles.
that added to the fact that my polar bottles taint the taste of my water is the reason I purchased a couple of these http://www.sigg.ch/
No they aren't cheap, but you can find them on ebay for $10-12.

Hey Some of the safest water bottles are the ones that hold beverages like Gatorade and water. They are free. Beats $12.00 Charlie

"Plasticizer migration" is the term for what I think folks are discussing here. It happens more when
the bottle is new. As the bottle ages, there is less of the stuff to leach out, so older bottles are
likely safer than new ones. As they age and the plasticizer leaches away, the plastic gets more
brittle, so your old brittle bottles are the safest, although more likely to crack and leak away your
water or other ride beverage of choice. If they are tasting a little musty from age but are clean
and leak-free otherwise, a drop or two of lemon juice when you fill them will help out.

Plasticizer migration is the reason people with fine musical instruments tend not to use plastic
accessories (straps, chin rests etc) unless the plastic is one of the truly inert forms like Bakelite.
The plasticizer chemical leaches into the air, and in the confines of a well-sealed instrument case,
can affect the organic lacquers and varnishes used.

Your not really supposed to reuse those my friend, recycle them but don't reuse them.
Health is much more important than money in my book.

I've found that a Nissan stainless bottle works very well, keeping liquid cold up to a couple of hours during summer rides. Easy to clean, very durable, and better cooling than the insulated plastic variety. Steel is obviously heavier than plastic, but I'm not a good enough rider to be able to notice an impact. I've not been concerned on organized rides or in open country about anybody taking it; in other circumstances (e.g. lakefront bike path) I just take it with me and refill before resuming the ride. To avoid metal/metal knocking, I put a polypro jacket around it (also lessens cold loss), but a carbon bottle holder would probably work also.

I used to reuse gatorade bottles as well. I dont see too much of an issue with those, but I wouldnt use one for more than a week before replacing it, just because I have no proof if it's good or bad to use them over and over.

If you do a search there's lots of into out there on it but generally what I understand is that reusing the plastic bottles could create a bacteria-breeding ground. Also, non-food grade plastic bottles made of polyethylene terephthalate can break down or leach with the addition of water, light and warmth. The litmus test is the taste. If you refill a bottle and the water has a plastic taste, discard it.

I heard a news report on this a few months ago, I think on NPR. They singled out plastic bottles that weren't intended for re-use, e.g. your basic Dasani or Evian bottles.

snopes is good, but not always accurate. When dealing with science there are too many differing opinions that for me personally if something truly seems as though it could be dangerous then I choose to be safe.

Most bottles are polyethylene that are sold as bike water bottles. Periodic cleaning with a brush
and hot soapy water will keep the mold growth down, but gatorade is a great breeding ground
so bottles used for gatorade and not emptied should be refrigerated, but be aware mold can grow
in 35-40F temps and over time will. So get bottles that are easy to inspect and clean, ie transparent
and without constrictions in the side walls. Letting the bottle sit around with a few ounces of bleach and
filled with water will relatively sterilize it after a few hours. If black grundge is in the bottle that is
mold. Camelbacks get mold in the plastic bag and in the tubing, hence the need for tubing brushes.
After a few biologic experiments early on I no longer put sugar solutions (gator/powerade) in camelbaks.
Nothing like a mouthful of mold casting from the tubing to give you a heads up. Steve

Back when I actually used water bottles I'd replace them at the start of every season. Which is every March/April. The cheap ones anyway. Then I bought the better Polar bottles & still have them in one of my kitchen cabinets. They don't deteroriate as fast as the cheaper type can, in fact mine never have & used to use them a lot & still do every now & then. And as long as you keep them clean, by putting them in the dishwasher after every use, you should never have a problem with them.

Haven't used a water bottle for bike riding for about 4 years now. I use a Camel BAK. In fact between my wife & I, we have 4 of them. All 4 water bladders are kept full of water, even when not in use, in the refrigerator with a plastic baggie covering the drinking end. After every use I refill them water & put it back in the frig. Like with the water bottles I used to use I cleanse the water bladders sometime in March or April. I use the cleaning tablets & kit Camel BAK offers. Otherwise they are always in the frig., full of water & ready for use.

So either switch to a better water bottle, clean the damn thing after every use, or switch to a Camel BAK.

A lot of the problem with water bottle problems is people do not keep them very clean. Then they wonder why they get sick at worst or get a sore throat at best. It's not that difficult people. Clean the things after every ride & they'll last longer & you won't get sick because funky stuff has grown inside.

Oh & one last thing. Never ever put sports drinks in any water bottle or Camel BAK. If you must drink a sports drink diring a ride that is fine. But either purchase the sports drink in the bottle it is sold in, most will fit in bottle cages, or stop to take a break & buy the sports drink then & consume it. Afterward throw the bottle the drink came in away.

I have a Gatorade(TM) bottle at work that I've been using for well over a year now. I work a strange schedule: seven days on, seven days off; twelve and a half hours a day during my "on" days. During my week off, I empty the bottle and leave it open in my desk drawer to dry out. Once every couple of months I take it home and run it through the dish washer. It's fine, no taste, no nasty stuff, still flexible. It doesn't fit my cage, but I have put it in my backpack when I'd forgotten my cycling bottle.

the leaching out of carcinogens in plastics happens at the temperature extremes. people freeze their bottles to keep cold..... BAD. even the heat from dishwasher can do this.
Put a capful of scope or mouthwash in the bottle and fill with water, let sit overnight then rinse. nothing grows on alcohol, and that is what mouthwash is.

They are pressurized, you pop the top and give a little suck and the water comes out.

Wow! Pretty anal about the whole thing.
Water bottles are great. One bottle has a Gatorade/water mix, the other water.
Can't always wear or don't always need a camelbak. If I go on a 35 mile training ride in the summer, 2 water bottles is fine and my back don't sweat. Unless I'm doing a unsupported ride/century into the desert, I never use a camelbak... except for hiking.
Rinse them out, fill em full of water and put back in the fridge. When you start seeing mold, put some soap, water and a handful of dirt in them and shake.

Look on the bottom of the bottles for a number 4 in the middle of the recyle symbol. That is safe.

Standard mouthwash is 10-20% etoh solution, usually 20%. (The cheap drunk: Kmart used to sell
1/2gal jugs of this for a couple of bucks.) Anyway, bugs will grow upto 8-10% etoh content, that
is how wine and vinegar are made, so a capful of mouthwash is going to be well under 1% etoh,
when mixed up in a water bottle full of water, no where near enough to keep bugs away. Bleach on the other hand is toxic at this level so a tablespoon or so will do the job. Doesn't taste great but not particularly toxic to people if you inadvertently drink some. Steve
