"It is a well known fact in the Army that you cannot clean a rifle properly and have it pass inspection. You can spend 8 hours on it running patches down the barrel, Q-tips, pipe cleaners, etc. Put a light coat of oil on it, put it in the rack, wait a couple of hours, and VIOLA! it now turns a patch black when you check it. What was the solution you ask? Well if the Army doesn't want their rifles oiled that is what they get. We cleaned them in the shower with SUPER hot water and some sort of cleaner that was in there. When you took them out of the water they were so hot that the water evaporated after about 20 seconds and a couple of shakes. No oil applied afterward. Quickly turn them in to the armory and let them wonder why they rusted. Its sad, I know, but what can you do when you are dealing with ignorant people. Sadly, I am now an officer and do not feel the need to "fight the establishment" to fix the problem. Just ready to get out."
Taken from one of your links Xant. It is not the best way for an average person who just started shooting a gun to clean a gun. Hell even this guy who is an officer in the greatest country in the world (USA) questions it. And again, the overall consensus is that you have to get every part bone dry after hot soapy water cleaning is used.
