Really clean.

Let me tell you another thing you can do to love your house more: hire someone to paint the trim. When they take off all the storm windows, get a two-quart bucket of water and add two tablespoons of vinegar. Wipe down all the windows with that solution. Go back over the glass with some Windex and paper towels or rags. Then go clean all the storm windows. Make sure you move the screens out of the way so all sides of the glass get clean. Stand back and admire your work. Or have a drink. Because it will take you all day.

But it's worth it. Because your neighbor will tell you your sparkly windows caught her eye when she walked by. And you'll need to wear sunglasses inside because the sharpness of the outside world will sear your retinas.
