I have an original braided cover for the tube that goes to the advance control in my 69 Hemi. It is much thicker than the current reproductions, which I think are essentially Ford products; anyway, I am trying to clean it of years of dirt and I am not sure how to do it. I was thinking of solvent cleaning, or even burning the dirt off, but I don't want to destroy it in the process.

Has anybody ever tried something like that? I have access to lab chemicals and hardware, if that helps. Thanx.
