Insert long rod, hit rod with hammer, break out guts of cat .....
Seriously though, never tried to clean one. I assume it is used?

If you're talking about the inside, just leave it alone. The catalytic material within the catalytic converter is fine. Don't try to flush it or anything. It may look dirty, but the first time it heats up it'll burn all that soot and junk off in moments.
Attempting to flush the inside with some cleaner interact with the catalytic material, causing some unwanted reactions and reducing efficacy and lifespan. Remember, the catalytic converter materials were chosen to work with three types of chemicals: air, air+gasoline/oil mixtures, and exhaust gases. Other types of chemicals can react/bond to catalytic material and render it useless. Inorganics like phosphites, sulfites, sulfides, and halides will poison a catalytic converter, while organic compounds like nitriles, nitros, and oximes can quickly do the same. Poisoning a catalytic converter is irreversible.
A lot of cleaners don't list the full ingredients on their label, so they may contain some chemicals that will react with the catalytic material. Even spraying the cleaner on the soot may create organic compounds that will poison a catalytic converter. So just leave it alone.
Though if you're talking about the outside of the converter, just take a wire brush to it to remove the rust.
