Well, I clean my guns differently depending on the gun. I've not seen any damage done to a gun that was cleaned after each time it was let out to play. I know guys that will clean and re lube after shooting for just 25 rounds. I know others that wont for over 500 rounds.
Honestly. I don't see where you can hurt it using the normal brushes. Now cleaning rods might be an issue but most of them are much softer metals that any barrel is made of so I would think you will mess them up before a barrel too. The worst I can see is getting metal stuck into the twist of the barrel. So..Go on..Clean all you want..Just be careful when you do it and all will be great.
