I knew a fellow that used to have them dry cleaned, at least the ones in consoles. Dry cleaners use perchloroethylene as far as I know so if you could get ahold of some of that it may work. I cleaned a grille cloth in a late 1950s radio last year using gojo and a soft tooth brush, and then rinsed it aff and let it air dry, it was glued to plywood and I did not remove it.
