De-bug the light fixtures

See that bug burial ground within your overhead fixtures? Turn off the lights and carefully remove fixture covers, dump out flies and wash with hot soapy water. While you’re up there, dust bulbs. Dry everything thoroughly before replacing the cover.

Vacuum heat vents and registers

Dirt and dust build up in heat vents and along register blades. Vents also are great receptacles for coins and missing buttons. Unscrew vent covers from walls or pluck them from floors, remove foreign objects, and vacuum inside the vent. Clean grates with a damp cloth and screw back tightly.

Polish hardware

To deep clean brass door hinges, handles, and cabinet knobs, thoroughly wipe with a damp microfiber cloth, then polish with Wright’s or Weiman brass cleaner ($4). Dish soap shines up glass or stainless steel knobs. Use a Q-tip to detail the ornamental filigree on knobs and handles.

Replace grungy switch plates

Any amateur can wipe a few fingerprints off cover plates that hide light switches, electric outlets, phone jacks, and cable outlets. But only deep cleaners happily remove plates to vacuum and swipe the gunk behind. (OK, we’re a little OCD when it comes to dirt!) Make sure cover plates are straight when you replace them. And pitch plates that are beyond the help of even deep cleaning. New ones cost less than $2 each.

Neaten weather stripping

Peeling, drooping weather stripping on doors and windows makes rooms look old. If the strip still has some life, nail or glue it back. If it’s hopeless, cut out and replace sections, or just pull the whole thing off and start new. A 10-ft. roll of foam weather stripping costs $8; 16-ft. vinyl costs about $15.

Replace stove drip pans

Some drip pans are beyond the scrub brush. Replacing them costs about $3 each and instantly freshens your stove.
