how often do you change your cycling bidon

Postby NBSE2 » Thu Jan 26, 2012 5:23 pm

Just wondering if water bottles do actually have used by dates. Where you use bottles especially in the heat of the day, where they heat and soften up, whether this impacts on the plastic in any way, potentially leeching chemicles and impacting on ones health. My general experience is that the higher quality cycling bidons tend not to be impacted by the heat however they are not stamped with a used by date.

The following quote sums up my concern.
“it now appears possible that some as-yet unidentified chemicals in these plastics (PET) have the potential to interfere with estrogen and other reproductive hormones, just as the infamous plasticizers BPA and phthalates do” source: http://dsc.discovery.com/news/2009/04/2 ... ealth.html

Any thoughts?

Id probably only ever change them or replace them if i lost or somehow broke one.


Could always try and find yourself some glass bottles... just make sure to never drop them.

Had the same 2 for past two & half years, was looking at them yesterday after my ride and thinking maybe I should invest in some new ones. Had thought they would last for ever!

I have too many bottles to count but i do have my favorites. I find the outsides get scratched up and look scungy. My theory is that the older the bottle is the more likely that if there was going to be leachate, it would have leached out by now and that older bottles = better. Like when you get a new bottle and it tastes plasticky and then the taste issue goes away after a few uses/washes.

Yep, I go by the same theory. Although starting with a good quality bidon like Camelbak gives you an advantage.

A soak in denture solution every once in a while to keep the grungy black stuff at bay. The outsides of mine look attrocious :lol: thanks to some wet weather trail riding at Terrey Hills. At least then nobody will steal them.

So nobody, you're on notice - I'm watching you very closely :P :wink:

I use mine until they wear out. The type where you push the top on tend to split at the same place each time

Sorry- also wanted to say that, after experiencing stomach upsets due to bacteria, my wife and I are fastidious at cleaning drink bottles. Once every 6 weeks or so we take the nozzle apart and clean it thoroughly on every bottle we've used. It is frightening how much horrible slimy stuff accumulates in the nozzle - especially if you use sports drink!

I have 4 ... And they are getting ratty. Kids use them for sports too. I just bleach them every week or so and rinse them well.
When I get round to unpacking some boxes I will find the 100's I have picked up after races ... But I don't like using them unless I have a few from the same team :-)

I've been using baby bottle steralizer. Once in a blue moon. Definitely some plastics especially if scoured on the inside can develop parmamould. I try to buy clear bottles only now so I can spot this a throw the odd bottle after this develops.

God mine would be lucky to get washed every 3 weeks or so. I only ever drink water on my rides though. I find the only time they get manky is when you use some sort of sports drink mix in them. When I was in the army I didn't wash a couple of my water bottles for 3 or 4 years with no I'll effects.

My camelbacks have this black showtime inside the suction nozzle and I can't get it out.
Might give denture solution a go.

Is there a trick to it? Or do I just leave it soak for a few hours?

Any other solutions if that doesn't work?

Come on guys, stick on the topic, NBSE2 is worried about the unknown chemicals that will increase his bust size, not gastro-inducing slime...

Aluminum or stainless steel bidons are available. I don't know how well the Kleen Kanteens work, though. The Al ones I have are great for bush walking etc, but the sports lid on it is horrible and I don't use them on the bike. They would be good for chucking at cars, though.

I change every 6 months, and clean the bottles with Milton anti-bacterial tablets (from chemist) monthly if I remember.
I've got a few of the BPA free bottles but I can still smell the plastic.
So with new bottles after cleaning, I take the lids off and let them air for about a month before using them.
There's less of the "plastic" smell.

Best cleaner is sodium percarbonate. It's the active ingrediant in napisan.

By getting it pure it's about three times stronger and has no detergants or perfumes.

It breaks down into sodium carbonate and oxygen. The O2 eats everything pretty effectively and it is non-toxic. Just give it a rinse afterwards and it's as good as new.

Like others - I have a bazillion of these things... but the ones in usual rotation are CamelBak ones. I give em a quick rinse and scrub with a bottle brush and then stick em in the dish washer. Clean as.

I've got 12 on top of the kitchen cupboard. Over time, I've bought bigger ones, for longer more intense rides.
The biggest are just shy of 1 litre.
Amongst the 12 are 3 I've picked up off the side of the road after mass rides. Perfectly serviceable. I clean these with kitchen detergent, then iodine solution for half an hour, then commercial strength bleach for 15 mins, then kitchen detergent. Seems like a lot of trouble but I have paid north of $20 for a bottle.

For summer, I have 4 favorites, and would fill them 3-4 times a week, and wash them not even once a fortnight in kitchen detergent.
I think the high turnover of fluid probably keeps mine cleaner. My ex might fill hers once every 2-4 weeks, and from time to time gets a black mould growing in them.

The most important thing to me about bottles is that they don't leak. In the car, I've resorted to carrying them in a bucket.

I think concerns such as this have to be kept in perspective. I know teenagers who won't drink fat reduced milk because they've read it is less natural and carries some health risk. And yet these same people binge drink and eat way too much animal cholesterol and starch, and no where near enough fruit and vege. The thing most likely to compromise Westerners' lives and put them in an early grave is artherosclerosis. And if you are worried about oestrogen, have a read up on the relationships between alcohol and excess visceral fat, and testosterone and oestrogen.

The clear nozzle is removable. You need to be very careful removing them though (i ripped one and without knowing there were spares available threw the lid in the bin(only a mud/dirt protector is available that wiggle carry)
My method is to twist the clear nozzle over the lips of the engagement valve and then try to pull it over top. Use warm water and a toothpick to scratch the slime/dried dirt out(this can be done without removing the nozzle from the lid but harder)

I have the same problem :D . If they reappear the tops are either chewed or missing.
