Vinegar's power doesn't stop at window washing. After you've tackled the windows, mix up a fresh 50-50 vinegar-and-water solution in a bowl and turn your attention to the blinds. Put an old sock on your hand, dip it into the solution, and run your fingers across the slats. After you've cleaned two or three slats, re-dip your socked hand, wiggle your fingers to swish off the dirt, and work on the next set of slats. Dry with a clean sock or rag.
