Can the volume control on a Philco 90 or 70 be cleaned using standard electronic sprays? I know that some of the older controls (potentiometers) were made by applying a resistive trace on a cardboard like backing. They could easily be damaged by any types of spray lubricants.

For the better part of thirty some years, I have been using WD-40 to lubricate and clean controls and switches with great success. But, I will not use any lubricants on the volume control of my Philco 90 until I find out more about this construction. It appears to me that it might be this earlier type of control. Can anyone provide some info on these?

Thanks,

Ed
