To clean the vents in a mobile home, use a vacuum cleaner to suction out dirt and debris from the interior vents. Crawl under the home to access the ductwork, use a garden sprayer to pump sanitizer into the ducts, and scrub the insides with a string mop. Finish by using a garden hose to rinse the ducts and allowing them to dry.
Begin inside the mobile home by turning off the heating and air-conditioning unit, removing the register and vent covers using a screwdriver, and suctioning out any dust, debris and dirt from the vents with the hose attachment of a vacuum cleaner.
Crawl under the home, remove the bolts holding the home’s ductwork in position using ratchet or socket wrench, pull the ducts free, and set them aside.
Using a garden pump sprayer filled with mold-killing sanitizer, pump sanitizer into the ductwork. Use a clean string mop and water to scrub the inside of the ductwork. Allow the sanitizer to soak in the ducts for a brief period, then use a garden hose with spray nozzle to rinse the ductwork. Allow the ductwork to dry for two hours before replacing any parts removed earlier by reversing the initial removal process.
Clean the vent covers and register covers in a mixture of one gallon of water and one tablespoon of dish liquid. Use a cleaning brush to scrub the covers before positioning them back in place.
