Is there a recommended cleaning guide on here for the 1911? Something with how to's, products to use, pics, videos, etc? Some guide on how to clean and lub after a session at the range? Also, if there are some minor scratches on a parkerized frame and slide, what is the best way to polish them out and clean up the outside appearance of the firearm? Thanks in advance Oh it's a Auto Ordinance 1911A1 5" barrel with a standard parkerized finish.
