7. Clean walls and touch up paint. Use a dusting attachment on your vacuum or an electrostatic duster to remove dust from walls, paying special attention to corners and baseboards. For a deeper clean, wipe down walls with warm, soapy water after dusting. Rinse with clean water, using a lint-free cloth. Touch up paint as needed on interior walls and trim.
8. Clean items on open shelves. Infrequently used items stored on open shelves can get pretty grimy over time. For items with a thin layer of dust, swipe with an electrostatic duster. If there is a thicker layer of dust, of if the items are in the kitchen (where cooking grease can be an issue), wash each piece in a tub of warm, soapy water. Rinse and allow everything to dry before replacing.
