I've got 3 Sigg bottles and i love 'em to bits (not that it has many bits!)
After constant use while walking, cycling, etc i have found, much to my horror, that they have furred up with a few patches of mold on the inside.

I only ever put water in them and wash them out every now and then.

I ask you to look in your bottles and see if yours have done the same.

the bugger is you cant fit a washing up scrubbing brush inside the narrow neck (and i'm a little worried that i'll scratch the inside making it worse)

Anyone else had this problem? any ideas on sorting it - i tried fairly washing up liquid, got bubbles but kept the fur!

maybe Cambridge has especially furry water!!!!

Cheers all

try sterident denture tablets.

Try Milton Steralising Fluid and a nylon bottle brush, works for me.

And store them with the tops off!

Try the intensive function on a dishwasher if you have one other than that hot bowl of boiling water and baby sterelizing tablets leave over night (also leave a window open most are chlorine based) then next day soak in washing up liquid and keep sawpping every hour or so if it can clean a manky camelbak it will easily shift mould from a siggs bottle.
ps does anyone know where you can get custom paint jobs for siggs bottles I would do it my self but I'm shite at painting

never had a problem with mine - they are always rinsed out, then filled with boiling water to sterilise (warn everyone coz they stay very hot for a long time). the very hot water evaporates quickly, leaves the inside dry. stored with the stoppers just turned enough so they hold - otherwise i would promptly lose them or the Angel will tidy them up for me (am i the only person to lose a compass indoors after it had been tidied up)

mm! not a lot of help about cleaning but may help for the future. good luck!

Just about everything said will sort it out. Also, try adding Bicarb of Soda and leaving to soak. Unsurprisingly, Sigg make a special brush for cleaning their bottles.

i dont own a sigg bottle, but ive a couple of platypus's and with it being clear i can see the mould growing in the creases at the bottom (mmm, tasty).

once clean, the boiling water trick does work, i also bunge mine in the airing cuboard for a few days to make sure it completly dry inside, with the lid off yeah!

Toothbrush.

Don't think I've ever cleaned my sigg out. Might be why the water gets a bit lumpy and chewy...

Is it OK to use bicarb in Siggs?I read elsewhere that it wrecks the inside.One of the big suppliers (Cotswold or F&T I recall)used to sell sachets of cleaning agent specifically for Siggs but I don't see them in latest catalogues.I wonder what the active ingredient was?

I stick my platypi (I have more than one) in the freeze after rinsing them out. Seems to work a treat.

Sigg own bottle clean,comes in pkts of 20,1xtab left in a bottle of warm water for 30 mins and bingo.

sigg say that the bottles interior is sprayed with "taste inert, food compatible stove enamel then baked"

wouldn't think that bicarb would even touch it but...if it does knacker it then i would definitely want my money back!

I was confused for a minute then and thought that this thread was about the Lord of a small Welsh town..
