I do use windex - the old fashioned windex with ammonia - the ammonia is a solvent and will remove light deposits of oil + it is a great bare metal cleaner - even starts the removal of copper build up - certainly not as well as a treatment of Bore Shine but it is an excellent metal cleaner. And of course the last thing ammonia evaporates in hurry and takes mositer with it...
The ammonia is so weak in that house hold product it is not harmful at all to your metal - just provides cleaning and stripping...
Here is a very good quote from a major barrel maker...
Dan Lilja of Lilja Precision Rifle barrels has never seen any damage in one of his barrels caused by the use of ammonia. Dan writes: "The rumor is that copper-removing cleaners with ammonia will pit and damage the interior surface of a barrel. Ammonia is very effective as a copper remover. We use solvents, such as Butch's Bore Shine, to remove copper during the break-in. We routinely leave Butch's solution in the barrel over night too. Again, I repeat, we have never seen a problem with ammonia in the concentrations found in commercial cleaners, in either our chrome-moly or stainless steel barrels. This includes examination with our borescope."
