ok, let me preface this a bit.
I've been a handgun shooter for decades. A cop for 31 years, a Glock armorer for 16.
My relatively new Glock armorer just announced that we need to be using denatured alcohol to clean our Glocks, because if we don't, he won't be responsible for the barrels pitting.
my first reaction was WTF ?
so, I do a little on line research, and find all kinds of posted crud about using off the shelf stuff, auto parts cleaners, isopropyl or denatured alcohol, etc, etc.
common theme appears to be, guys that are to cheap to buy a good gun cleaner.
so, comments ? recommendations ?
because my gut response is to throw his alcohol away and tell him to stick to the good stuff, such as Hoppe's #9 and MPro-7.
