Keeping the Keezer dry inside

Keep in mind that a properly built keezer, while hardly a PITA, is not entirely maintenance-free. Despite your best efforts at sealing and dessicating (is 'dessicating' a verb?), you'll still need to empty and clean it regularly. Condensation is a fact of life and the water that results can, indeed, be problematic (mold, slime, corrosion, etc.). Damp-Rid will buy you some extra time between cleanings, but it won't eliminate it. Mine gets a thorough cleaning roughly once a month, or any time a keg kicks, whichever comes first.
