Like just about everyone else here I either use dish soap and swish or around and/or a brush to scrub things, or a bleach solution. Then hang overnight to dry.

Also like a lot of people if I have anything left in or such as water or water with CamelBak's Elixir add or all goes in the fridge.

I do like the denture cleaning tablet idea. Especially after reading the precautions on CamelBak's cleaning tablets.
