Bladder Mildew

“I seem to have gotten some mildew in my hydration bladder. Should I just toss it, or can I effectively clean it with a bleach solution (10:1)?

I think that the mildew will still leave the stains, but the smell and nastiness will be gone.

Help?”

“A bleach solution will do the trick. Just let it sit over night and the bladder will be as good as new.”

“This sounds like a personal problem - please consult your doctor....”

“LZ is right. Just use some bleach, and really hot water. Shake it around and let it soak for a day or two. There are bladder/hose cleaning kits you can buy but They cost just as much as a new plattypus bladder. Seems kinda silly to me.
If you can't get the funk out get a new one. They aren't that expensive, and next time store it empty with the cap off. This should prevent the problem from recuring.”

“I'm doing that this evening. I missed a couple outings cause the green goo was floating. It don't take long for the gunk to show up in hot humid weather specially when it's had stream water in it. I thought keeping it in the dark would forestall the dreaded green goo. But no such luck on this one.”

“I keep mine in the freezer between trips... doesn't allow anything to grow!!!”
