It seems there are two schools of thought for using lubricants:

1. NEVER use lube on anything because it will gum up and cause problems
2. Superlube can and should be used on EM stepper contacts to keep them shiny

I have been battling with wiper contacts on the drop targets on a Williams Flash. Once they stop registering reliably, I will disassemble them and gently clean both the horseshoe contacts and the wiper boards to a fine shine. Within 3 months of casual play (maybe a few games a day), the wiper boards are dirty again.

The question here: Would a VERY thin layer of Superlube help keep the boards cleaner for longer, or am I looking at disaster? The wiper boards with contacts sliding on them seem completely analogous to stepper contacts.

I feel like the super lube lessens conductivity in exchange for a lessening in friction. If you drops are still dropping fine (and not sticking) then I don't think it'll help. Worth a shot though.

Are you cleaning the horseshoes as well as the boards? Removing polish residue afterwards? Seems like it shouldn't get dirty so fast.

The original Williams boards are bare copper. If you clean the copper foil, a few weeks later it all tarnishes again and needs cleaning again. The reproduction drop target boards are tinned copper so that tarnishing won't happen. Do yourself a favor and buy the new reproduction boards.

I use a thin layer of dielectric grease. Works great. Available at your local autoparts store.
