Default How does one unclog catalytic converters most easily?

I just took off my airpump and sealed the tube. I did this not really for performance or aesthetics, but more because of the noise of exhaust coming up through the airtube making a loud put put sound that can be heard in the cabin with the soundproofing now removed.

I have a pair of aftermarket cats on a crappy summit h-pipe welded down right before the crossover tube, So I could technically get at the back of the cats if necessary. Could I run water through them? They're not clogged (yet), but I suppose they will be shortly.

What exactly is in a catalyst anyway and what would damage them?
