While pairing cars with vodka might seem like a terrible idea in most situations, in this instance, it is pure genius! When you’re out of washing fluid and a trip to the store sounds like too much of an inconvenience, simply visit your liquor cabinet and grab your vodka bottle – next, mix 3 cups of vodka (in this case: the cheaper, the better) with 4 cups of water and a few spoons of dishwashing detergent. Mix the ingredients well and voila! You’ve got yourself the perfect filler for your windshield-washer reservoir.
