Lol as much as you want, sometimes holding then gently down behind the head, isn't always as easy as it seems. I have a male ball python that is quite young. Yet he is the most agressive snake I have seen, he beats the amazons and emeralds I have been in contact with. Right now, the size doesn't bother me much.
What I did to help him shed (which you could do to clean them), is put them in a warm waterbowl with a lid and a few holes. I let him soak in there for at least an hour and then let him bite down on one of my gloves and removed his old skin.
