Removing lead buildup from barrel compensator
 

I use a screw on comp on a Ruger 22/45 pistol. Over a couple of years, the lead deposits finally built up to the point the openings were nearly clogged. What is/are the best ways to remove such deposits?

What about a #1 drill bit twisted in by hand?

Unscrew comp from barrel and replace?

Anything you do to work on getting the lead out will just be exposing you to more and more of the stuff.

Got a sonic bath?

if you can get it, blob of mercury will dissolve any lead.
So ideal to restore a high end rimfire match barrel
or that compensator

just be careful to recover it since both lead and mercury are toxic.

Good thoughts, all! Thanks. I wound up using a small diamond bit in a Dremel tool to remove the lead. To minimize exposure to the lead dust I wore a mask and worked over a dampened paper towel to catch and hold debris. This worked quite well and had the offending deposits removed in short order. I will be more observant in the future and not let the deposits build up!
