Here's how I clean the bottom of my frying pans: with a detail sander.
Take a look at the pictures -- those are at least 1mm worth of burned in oil at the bottom off in a few minutes with the detail sander. Yea, Hah! That is how a man clean his tools. Well at least this man. That is a 60 grit paper on the sander since I neglected these pans for a while. If your pans are not in such a state use a smaller grit like 120 or finer if you want.
If you don't own a detail sander then use elbow grease -- it would only take longer to clean so the Lazy way is out for you.

See how easy that was? You too can achieve the same result with little effort. Clean like a man the lazy way ALWAYS!
