11.Forgotten Areas
Cabinet tops and vent hoods are a couple of places people sometimes forget to clean, along with behind toilets and under bathroom sinks. Wipe them down every so often with warm, soapy water. Give your pets’ dishes a daily wash, too, and check around for other areas that might collect grease, food, grime, or water.
12.Furniture
Fabrics can trap dust, pollen, and other allergens. The next time you give the living room a new look, consider leather or vinyl furniture instead of cloth. If you have issues with allergies or asthma, you also might want to hang blinds instead of curtains, and dust them regularly.
