I'm curious how far you 22A owners strip your pistols for cleaning. I took the grips off so I can spray the inside of the magazine well with powder blast without damaging the polymer grips. I was going to blast the whole thing, but I'm not sure if some of the parts need to be oiled/greased. Any input?

 

Edit: Added pictures with grips off. This is the sludge I want to remove. I'm not sure if it's grease or just built up powder residue.

I only took off the grips once.

 

typically, just take off the barrel, clean it, the slide, the receiver. I then take a large patch and clean inside the frame.
