Whats the best way to clean out the channels and de-burr/de-nick some m3s?
-
I use the 3M sanding sponges. The one that has the 45 degree angles will get up inside the channel perfectly.

I gotta try one of those--the 3m green pads are good with press wash, but you have to shove them into the channel to get it nice and clean.
The scrub pads won't touch a nick or a burr, but cut into any ink or adhesive residue pretty quick.
Is 60 grit pretty tough on them, or is it not quite the same as standard 60 grit aluminum oxide?
-
Scotchbrite, 600 grit wet dry, and a nice flat blade object like a large flat blade screwdriver with the side edges rounded so you dont make high spots when massaging out dents.

I've always gotten moderate nicks and imperfections with the med and fine grit sponges. Never tried blues way but it would work great that way too. I also use the sponges to get tape and adhesive off frames, oh, and ink and dried emulsion.

Never considered the sponges, picked up some last night to try.
I have always used a flat screw driver with the tip bent to scrape the crud out followed by a stiff stainless steel wire brush.
Dents get worked out with a screw driver.
Burs and Knicks get the file, Emory cloth and then a Scotch Brite pad or a small wire cup brush on a die grinder. The cup brush is great for taking rough edges off especially on aluminum.
WD-40 works good as a cleaner, a little scrubbing with a course scrub pad and it will take off the emulsion, ink and tape residue.
