Elite Cleaning Services? staffers spend between two and three hours scrubbing each DC-metro-area home they visit during their convenient Monday?Saturday workweek. Professional grime eradicators descend on cluttered homes at appointed times between 10 a.m. and 6 p.m., dusting knickknacks and sweeping, mopping, or vacuuming floors besmirched by foot traffic or one to three Stooge houseguests. Workers take special care to sanitize kitchen fixtures and bathroom furnishings, and leave kitchen-appliance surfaces looking polished and magazine-shoot ready. For smoothest service, Elite recommends that clients leave staffers a list of cleaning preferences and items that they shouldn't touch, stack fresh linens on the beds, and clean up any scattered toys, clothes, and flesh-eating chupacabras lying around.
