Hi,

Except for the complexity of correctly spelling "paraphernalia maintenance", and the obvious potential implications of not including that all-important modifier "coffee", I'm hoping there are straightforward answers that I just haven't encountered yet:
How do you clean the coffee residue build-up off your favorite travel mug, brewing rig, etc? Daily rinses and washes help stem the build-up, but soap and water don't take care of all the residue that can cake on over time, and brushes that are soft enough to not scratch up a steel mug aren't abrasive enough to take care of all the build-up. So, what do you use to do the periodic cleans to get all that stuff off? Any recommended chemical solutions that don't require scrubbing access to all the nooks and crannies of a travel mug?

Any help will be apprecited.

I didn't find the right solution from the Internet.
