If your local O'Reilly Auto parts store has them, these aluminum pans they sell are fantastic! Inexpensive, can be cleaned and if parts drop in them they don't fly over in a corner never to be found. I keep one under my Triumph TR-6 and one under my Park stand. They are about 36x25x3/4. Big enough to catch cleaners and oil and small enough that they don't get in the way.
