I'm not doing a full cleaning, just a field strip. I do want to get an ultrasonic cleaner to dip the trigger group into, though.
But yeah, I've been taking things apart and putting them back together for a long as I can remember. I had a little slot car track when I was seven or so, and I'd take the electric motors from the cars apart and clean them, taking lap times before and after to see how much faster a clean motor would go.
