Dust Air Vents
You may not notice the air vents in your home regularly, but they can quickly build up dust around the vent and wall areas. Dust them down monthly to keep dust from blowing out into your rooms. Wipe down the nearby wall as well to remove any dust that has accumulated there.
Even families without small children will discover occasional marks on the walls of their home. Spot clean the walls of your home to remove crayon marks, furniture scuffs, dust, and splatters. Food preparation, eating areas, and the place where you store your trash will be likely candidates for a monthly wall wipe down.
Clean Window Treatments
Curtains and drapes may need to be washed, cleaned, or dusted out on a monthly basis. Blinds that attract dust will need to be wiped down as well. Be sure to check the manufacturer's instructions for your window treatments before cleaning.
Besides the quick dusting that you do on a daily and weekly basis, more intensive dusting needs to be done monthly. This is the time to reach deep behind furniture and appliances and dust window sills, ceilings, and baseboards. Don't forget to dust down your doors, molding, and hidden corners were cobwebs may form, too.
Vacuum Inside Furniture
It is amazing how so much stuff finds its way into the depths of the sofa and living room chairs. You may not know how it got there, but a monthly cleaning and vacuuming is likely to reveal many long lost items and quite a bit of dirt.
Go down into the crevices to pull out items and either throw them away or place them where they really belong. Then, vacuum under and around the cushions to get rid of dust.
