What builds up between visits that you stop seeing
In a lived-in house the grime that matters is the slow kind. A film of cooking grease settles on the cabinet fronts above the stove and along the edge of the range hood. Soap scum hardens in the corners of the shower and along the rim of the tub. Dust draws a grey line along the baseboards and collects at the base of every lamp, where a quick wipe never quite reaches.
None of it looks dramatic on any single day, which is exactly why it gets past a household. After a few weeks the kitchen feels faintly tacky and the bathroom never looks finished. A recurring clean is built to catch these layers before they harden into a project, and that is what homes and condos around Elkhorn use Shelly's for.
