How to clean water bottles?

[GLC1968]

I believe that the spouts on a polar bottle come apart for cleaning, do they not? I would remove them and soak them in a bleach disenfecting solution. 1 T bleach to 1 gallon of water should work - 5 minute soak about all you need. (this is what we use to disinfect our dairy bottles & equipment for fresh milk - no bleach smell remains once the items have dried completely)

We just put ours water bottles in the dishwasher every once in awhile and we store them with the spouts open. I've never had a mold/smell issue.
