what do you all recommend to clean a shield? I have hoppe's no. 9 bore cleaner that I used for my first cleaning after I shot both on the front of the polymer frame, throughout the slide and on the trigger group. I went back through and lube lubed it up but I'd like something a bit "safer" as I've been told no. 9 is not good for this gun. Any ideas? A scrubber? Anything? Thank you
