what to use when cleaning a metal finish is a common question-
and many of us recommend the frontier pads with a solvent
i am cleaning up a particularly cruddy grade 2 that suffered from poor storage- screws are great and there is a lot of case left under the dirt and rust-
these are from the first round of cleaning- and except for a little polishing on the mainspring - this was done with just a frontier pad and Hoppes 9
the top lock after a cleaning -it looked like the bottom one to start notice the case remaining on both
An inside view - the left lock is slightly worse inside than the right started out - but only slightly
And a close up- the case washes out some from the flash, but I think you'll get the idea
And a bright shot to highlight the condition, not the case
I'll post some final shots when i get the rest of it done, but I hope this helps show what the pads can do
PS we all like our "unturned" screws on Parkers, and I really doubt these locks have been out of this gun since it left Meriden, but look at the picture of the insides of the locks, see the slight damage to the slot of the lower bridle screw on the left -- I DID NOT DO THAT
it came that way, really
