This is what I do for deep cleaning my pistols. I don’t want to get into the endless debate over how and when you should clean, that’s up to you. I am only showing what I do.
This is a shot of my setup before initial take down.
I use my Harbor Freight ultra sonic cleaner with a 30:1 ratio of distilled water:Simple Green set on heat for 16 minutes. 8 minutes flip / adjust parts another 8 minutes. Small parts go into a jar or solution filled zip lock bag.
Then I blow everything off:
Then I drop the parts in my Bald Eagle ultra sonic cleaner with a 20:1 ratio of Distilled water:Ballistol set on 122 degrees for 20 minutes. 10 minutes flip / adjust parts another 10 minutes. I put the small parts in a jar with the same solution.
I blow and wipe everything off then lay the parts out back on the work bench.
Then I put it back together and function test. Ready for the range.
