I have a graded Baker (R or S) that I am cleaning up. I have the stock removed, the side plates off and the trigger plate removed. I have left all the pins and bits and parts withing the receiver where they are. My question is what do you recommend to remove the gunk, oil and varnish from with in. I started with CLP Break Free, this seems to work some using a toothbrush, is there something else I can use for this?
Should I try to disassemble further?
The receiver is not rusted, but there is not a lick of case anywhere, either it was removed a long time ago or it was never there. What would you recommend I use to clean this up without removing the engraving?
