I keep on hand a couple of bottles of the cheapest vodka I can find. Anything I'm concerned about (Camelback-type bladders in particular) get a liberal dose of the vodka to sterilize and dry them...and then I drink the vodka.
Sometimes I rinse things out 3-4 times just to be sure they are clean.

I do the same thing with Isopropyl Alcohol. I have bad skin reactions to a lot of cleaning products. Doctor's aren't sure why, but an allergist suggested using Isopropyl Alcohol for cleaning to prevent any reactions on my part. I find it works great for my bladders.
If I drank Isopropyl Alcohol, it would sure clean out my bladder!
