From the whimsically-named "Gaurd Duck" at Mental Militia:

I use cheap vodka to clean house. It has orange oil in it and both that and the alcohol are good degreasers.
It is called Burnet's Orange Flavored Vodka. Don't drink it, it's crappy.
Cleans the stove good though, and our teapot, and it even gets the smell out of spaghetti sauce jars!
It gets the tea stain out of enamel cups & sanitizes counter tops after cutting meats.
