"Water!" That's the word I couldn't remember. Thanks, guys.
In olden times we used that stuff to clean guns because we weren't smart enough to buy the more expensive stuff. We'd even fill a bucket with wawwa ... uh, water ... and soap, dunk the gun, then scrub it as needed, and rinse it off in more of that wadder ... uh, water. Hot waw ... wad ... oh, darn, water is better than cold. It dissolves yuckies faster and the parts dry faster when removed from it. Then we'd lubricate everything with earl ... oriole ... darn, I've forgotten again. At any rate, we'd use that stuff and the gun would be good to go.
Way, way back in the dark ages when there was only corrosive ammo and there was a battle--like in a war--no one would fight unless there were taps marked "H" on the battlefield. That's why we lost both World War I and World War II and why everyone in the U.S. speaks German and/or Japanese today. The Axis (Germany, Italy, and Japan) weren't so particular about gun cleaning so they won the wars.
Steve is right about the car washes but wrong about the signs. I've never been able to correct Steve before about anything because he knows more than I do. For that reason I leap on this opportunity.
It is true that many people seem to think that a "Car Wash" is intended for washing automobiles, but if that was their purpose they would be labelled "Automobile Wash," so it's obviously not so.
Gun people know that the word "Car" in those signs refers to collapsible AR stocks: all of those places were built so that people could clean rifles in them. Of course you're not restricted to washing AR-15s with CAR stocks in a "Car Wash." It's just a handy way to refer to them. Now if only people would stop cluttering them up with vehicles the world would be a better place. I hope that Steve doesn't mind this correction. I know a great many things, a few of which are true.
