Many people enjoy a hot caffeinated beverage in the morning or a cold, bubbly cola in the afternoon, not just for the taste, but for the caffeine pick-me-up. But those caffeinated drinks can do more than just put perk in your step. They can clean everything from your windows to your floors. Check out these simple and—perhaps—unexpected ways to clean with caffeine.

1. Make Your Windows Shine with Black Tea

The tannic acid in black tea dissolves dirt and grease, making it a simple and accessible cleaning agent. Brew a batch of strong black tea by pouring about 8 ounces of boiling water into a bowl with 3 bags of black tea. Let steep until it is completely cooled. Then, pour it into a spray bottle and set to work.

The tannins in the tea remove dirt and grime, while softening the look of scratches and dings. As with any floor cleanser, be sure to first test a small, inconspicuous spot to ensure the results you want.
