4. Make the Windows Sparkle

Clean windows inside and out to make your home sparkle. If your home’s windows tilt out, it’s quite simple to wash exterior windows. Otherwise, you might need a friend or family member to steady a ladder while you do the work. Try washing outside windows by spraying them with a garden hose to remove dirt and cobwebs. Then sponge them down with a small amount of vinegar or detergent diluted in warm water and rinse. If you need to wash your windows from the outside and your windows don’t tilt out, try using a long-handled brush.

Approximate cost: Next to nothing, if you wash the windows yourself. But if your windows are high up and you need to rent a ladder, a 14-foot ladder will cost about $25 to rent for four hours from a big-box home improvement store.
