Hi Kev 74, i read and own that same book. And do the same but i dont have the sonic cleaner, i imagine how good that will work. Mineral spirits clean everything off , like strips all the oil. I love that squeaky clean feeling it gives. Good when you want that deep clean, especially if you want to try a different type of gun oil. Also it does not harm plastic stocks and such. Although i wear rubber gloves because it does dry out your skin real fast, also air drys itself quickly to. i dont use air to blow nothing off. Again the air would be that nice next step though. Good stuff, I like sweeney i like the way he writes i try to buy all his books, good guy. He has that no nonsense way about him and he calls it like he sees it, when he tests guns in his review he is relentless, he puts them to thier paces, no favoritism. They tell him do not use steel ammo, he uses steel ammo. If he gives something a good write up, you know that it is a good gun. I just seen he ran 12,000 rds thru the new ruger 9mm Sr pistol with out cleaning, and it is still shooting.
