    What kind of grease if any are you guys using in the switch cups that the center post contacts. All of my machines have something there. I imagine it's the same type of grease used on the reset assembly motor wheels.

    I keep them nice and dry. Eventually the grease will just gum up with dust and crap and it won't work properly. Polish the cups and they'll be nice and slippery anyway.

    Nice and dry they shall be. Curious what all the black gunk is that I'm pulling out of them, really yucky, dried up stuff.

    Some guys put grease in the spoons and it turns into what you are seeing.
    If you clean the spoon with Plexus it will shine it and make it slick and as a bonus it repels the magic dust.
    I use this stuff on all my plastics.

    Plexus™ was developed for use in aviation, specifically for cleaning and protecting aircraft windshields and painted surfaces. Its quite simply the most effective product you can buy for cleaning, polishing and protecting all clear and colored plastics and painted surfaces.

    Plexus is easier to use, and leaves a noticeably cleaner, more lustrous finish than conventional polishes. It protects by actually sealing the pores in plastic making it more resistant to debris, oil, bugs or scratches. And because its anti-static, it repels dust and lint. Its perfect for windshields and the leading edges of the wings, as well as for removing exhaust stains and cleaning wheel wells.

    Also, Plexus polishes without harmful abrasives. It leaves an invisible, micro-thin layer of wax without smears or smudges. It dries to a crystal clear luster, leaving no oily, sticky or tacky residue. Its the ultimate detailer for your aircraft and pinballs. So, if you're looking for a better way to save time, money and help protect your valuable investment, its clearly brilliant. Plexus. Clearly the best.

    That is the congealed, decades old lube that Woz noted...

    FWIW; I use MBI Instrument grease in the bumper switch cups. That is probably what you are finding gummed up there. MBI grease is "non-gumming" but any grease that is 30 years old is bound to have dried up being exposed to air etc.

    I've been using white lube in my pop bumper switch cups but redo them once a year. Never had a problem doing that in all the years I've been involved in collecting and working my routes. I think MBI is also an excellent choice but I've never tried it in pinball, I'll have to give it a shot next time. Thanks for the suggestion.

    MBI Instrument Grease is what Williams originally supplied in a squeeze tube with every EM Williams pinball I ever uncrated. Bally supplied it too. They both labeled the tube, "Coin Machine Grease" and in the fine print on the tube said MBI Instrument Grease.

    The pop bumper spoon was greased from the factory. Today I use Super Lube synthetic grease from a squeeze tube on the pop bumper spoon.

    #10 8 years ago

    That's funny, I've never read that tube but I have used it in pinball then. I use MBI in my fishing reels because it's so thin but holds where it's placed and doesn't seem to break down in water (don't ask how I know this).

    I have a tube of that Bally grease I found in an old em, the stuff is hard as a rock.
    It was probably state of the art 30 years ago but then again so was I.

    #12 8 years ago

    Photo of various tubes of pinball grease that were available. Bally free samples, Bally sold tubes, Williams sold tube and box as the Williams version is in a metallic tube (that one was bought around 1972). And finally a tube of genuine Gottlieb "White Lube". I believe that Gottlieb White Lube is Lubriplate. Still available. All of them, procured in the mid '70's are still good. All have been stored in the usual "cool, dry place".

    You were state of the art or hard as a rock 30 years ago

    This is what I do and have never had a problem, but everyone has their way of doing it. As far as any wear caused without grease added there would be none. You have metal to plastic. The general rule for lubrication in pinball machines is metal to metal only. I think it was overkill by the manufacture to make it a rule of thumb to lubricate the Pop Bumper Spoon to begin with. To me lubrication would only cause you grief in the long run as it will just do the same thing again that you are already dealing with, a gummed up part.

    Plexus is a fantastic product. I use it on the windscreen & plastics on my motorcycle. Nothing else compares.

    Clean and dry and polished spoons work the best for me. I usually find that gunk on old metal spoons and clean them off with wd40. It is a great cleaner for that purpose. Just spray a little on a rag and clean away. Then I smooth them off with a super fine steel wool and give them a final wipe with a microfiber cloth. If the cloth feels "snaggy" then I know there is more steel wool work to be done. Plastic spoons cleaned with novus2 works for me. I'm very interested in this plexus product now though. I will have to get some.

    Be sure to keep hold of those tubes with the pin MFG logos, especially that brown box. The box may eventually become more valuable than the tube of grease for some collector.

    Far as the bumper cup, mine remain dry and grease free.

    I understand Caig # L260-N1 grease is very close to the original MBI Instrument Grease.
