how do you clean the bottom of the container?...
how do you clean the bottom of the container? does the bottom screw off for easy cleaning?
i just shove a soapy sponge down there on my Primus bottles and work it around with a wooden spoon, but I'm decidedly low tech..
I would use PBW (look at any home brew site) for tough stains or residues. It will clean almost any surface to prefection given a little time and hot water (no scrubbing). A bottle brush should deal with all of your day-to-day cleaning.
