In the manual that came with the book is there any instructions for cleaning the rifle? There are many ways to clean them. You have to break the rifle down and clean all the parts. Then clean the barrel and receiver. Oil the barrel when your done, oil all the parts and put the gun together.

Some do water bath their inlines, some do not. It is all a matter of choice. Just make sure you clean it good and get all the powder and fowling out....

Good luck
