For routine maintenance, people have been efficiently and effectively cleaning the barrels of their guns using Hoppe's #9 and its equivalents for more than a century. And light machine oil (i.e. 3IN1 and equivalents) has been used to lubricate and protect those guns for at least as long. Further, it is recommended in the manual of every commercially produced firearm I have owned.
They are simple, easy to use, effective and cheap. What would possess someone to go off and experiment on something as expensive as a firearm with something that could easily turn it into a pile of rust? The quest for novelty - apparently for novelty's sake - is something I do not understand. I have firearms that are nearly 80 years old still in regular use. I'm going to trust them to what I already know works for the long-term.
Of course, if you have an unusual problem or one normal maintenance can't resolve, then you have to try something unorthodox, but there you either experiment or the gun becomes a wall hanger and so you take risks. But then by definition that's not "routine maintenance".
