Let the sun in. Make any room look brighter with clean blinds and windows. Mix a solution of one part white vinegar to eight parts water, plus a drop or two of dishwashing liquid, for a green window cleaner. Spray on and wipe with newspaper to avoid streaks. Washing on a cloudy day also reduces streaking.

Sniff out smells. Check the drip tray underneath your refrigerator and wash out any standing water from defrosting. Remove inside odors by washing the inside of the fridge with a baking soda and water solution. Boil lemon juice in your microwave and add it to your dishwasher to eliminate bad smells. Also, put the lemon rinds down the disposal. Add activated charcoal in the fridge to keep odors at bay. Make your bed better. Vacuum mattresses and box springs, and then rotate and flip over. Do the same for removable furniture cushions. This is also a great time to wash or dry-clean the dust ruffle and mattress pad.

Clean those coils. Improve energy efficiency by vacuuming grates, coils, and condensers in your furnace, stove, and refrigerator (either underneath or in back). If a vacuum won't reach, try a rag tied to a yardstick.
