I use Servisol to clean valve pins, but I spray the pins rather than the base, then quickly place the valve back in the base. I leave it a couple of minutes or so to allow any surplus cleaner to evaporate before switching on. I've never had any problems doing this. I've found this method of cleaning particularly effective with loctal valves.

I did wonder whether is it possible that the chemicals in Servisol could damage valve bases, particularly those of bakelite or ceramic manufacture?
