Should you clean your gitch? Only if there's skid marks

It's easy man, just don't let the res build up. The bowl itself is easiest to keep clean, just wipe it out after every use. The stem will need some 420Solution or any other kind of cleaner you can buy at your local headshop.

Or if you are poor like me, a combination of boiling water, rubbing alcohol, sea salt, baking soda and lots of elbow grease will clean anything!
