On a wholly unrelated note, if you've ever tried to clean something greasy or oily, for instance spreadable butter, off of a slick surface, for example the storm window on the front door, you'd know that water doesn't work very well.
I'd like to recommend Windex with vinegar. It takes butter (or other oily substances) right off windows (or other smooth surfaces). It does well on doors, hardwood floors, linoleum, and tables too.
Don't ask how I know. Let's just say even a lethargic toddler can manage to keep his mom on her toes.
