did Bill's suggestion with the HCL I got at the hardware store. It was successful in removing the staining I did with the clorox, but I'm still back where I was with the fire stained issues. The polymer is fine except where the fireman's axe nicked it a little. The same axe smacked a Glock 36 right on the slide and it narrowed the channel to where it wouldn't come apart. A little vise action and persuasion got it straightened out. Runs fine now just like the Kahr.
Saw a guy who polished his CW slide and it looks great. Might try that. Borrowed this from Kahr Talk forum:
