At home, Sandra says she like to keep everything organic, including her household cleaners.

Though there are many "green" cleaners on the market, Sandra says you can get the same effect—and save money—by using items found in your cupboard. "An easy window cleaner is just a cabinet away," she says.

To get streak-free windows, Sandra mixes three tablespoons of vinegar, a third of a teaspoon of pure liquid vegetable soap, like castile soap, and two cups of water in a recycled spray bottle. "It cleans your windows like crazy," she says. "Oddly, the vinegar smell doesn't linger."
