what is the best way to clean a stainless barrel on a muzzleloader?

i have a CVA stag horn and it has a stainless barrel on it and i have never cleaned one in my life and i need a little advice on cleaning it.

Is it just like any other barrel that i've cleaned? just use soap and water and oil and grease it down after words?
