Go to the horses mouth. "Call Kahr".
When instructions say to spray "cleaner " into the gun mechanism, such as the striker channel, are they refering to the likes of un-clorinated brake cleaner to completely de-grease/de-oil or something like Break Free CLP.
I hear folks say all the time, the brake cleaner has the same ingredients that gun cleaners have, and brake cleaner is cheaper. Perhaps the same ingredients, but take a close look at the percentages of each. I've seen some nasty results of cleaning guns with automotive cleaners. Spending hundreds of dollars on a gun then risking damaging it to save a few dollars, doesn't make sense to me.
To each his/her own.......
Brake cleaner melts many plastics. Either use "Plastic Safe" gun cleaner or what I use is Kerosene. You can get a squirt bottle for it or just put it and the gun in a pan and slosh it around. Use compressed air or "Canned air if you wish to dry it quickly.
