The recipe I use is 2 cups distilled water, 2 oz vodka and 8 drops of essential oil...I prefer lavender as it is a lighter scent. I also use vodka to clean my windows, remove stains from carpet, great on mirrors...the reason being is that one day I sent my DH to the local Krogers to get 3 items, he came home with much more including a gallon jug of no name vodka. Evidently, the customer in front of him in line did not get all his groceries. I called Krogers to let them know that we had the man's vodka and the manager laughed and said - we have taken care of him, keep the vodka. So I have been trying to use it up for awhile now. The recipe is passed around our guild several times a year.
