Cleaning Metal Files - Model Railroader Magazine

Bob,

Good tip on the suede brush. May be hard to locate, but I'm sure they're still out there.

Yeah, a knife tip would help with a small spot of solder, but I just finished building a brass loco and the issue is rather more extensive. I may just buy a new set of jeweler's files, these have served me well.

I suspect that the solder I'm still seeing after a good brushing is merely surface and not really a buildup. It's shiny so catches the eye, but may not really interfere much with the action of the files.
