If the breech plug comes out and the barrel comes out of the stock, then clean it through the barrel. I do not run a water bath normally for my inlines unless they are really filthy. I use a patch soaked with dish washing water and run two or three of them from the breech to the muzzle to get the major fowling out.

Then look through it, it will look clean but you need to clean the breech threads. So this is where I put a nylon breech brush and wrap it with a large patch. I soak that in solvent and then reach in there and clean the threads. Check it with a flash light to make sure the threads are nice and clean. After that a bore brush run through and back a couple times, and then a couple solvent patches and a couple dry patches and the barrel is normally clean. Just make sure you clean the striker area real good. I like to shove a paper towel in there and then soak it with dishwater. I then twist it back and fourth until all the fowling is out of there as well. Then another paper towel and dry it. Oil the thing up. You should be good to go.

What model rifle do you shoot?
