    Quoted from Yuyito:

    I second that. Stay away from "Classicgameparts" on Ebay the guy is a hack. Way overprice for the low quality of work that he does. I ended up fixing the board again after he so call fixed it.

    Oh my, I fell for this and I had the same exact experience with this guy. Sent boards to him in May, ad said I would have them back in 2-3 weeks. Finally got them back in October and he sent me an MPU that was not mine. Took at least another month to get my MPU back and I'm now left to rebuild my driver board again myself. Going mosfets this time.

    Crap, horrible quality work, took months longer than estimated, would barely respond and I'm left redoing his work. Actual website is http://www.pinballrepair.net/ (confirmed, I called). STAY FAR FAR AWAY.

    This was for my first pinball I bought Flash. Was a newbie and didn't want to do more harm than good, didn't yet know about this site so I fell for the ebay ad.

    BTW I have used "The Works" toilet bowl cleaner with success. It's found just about everywhere and it's dirt cheap ($1.65 at Dollar General stores). https://www.dollargeneral.com/the-works-disinfectant-toilet-bowl-cleaner-32-oz.html?gclid=Cj0KCQjw-uzVBRDkARIsALkZAdlXbu0pqBMM5ha55HZcICvBetzzcXx6i-_Oxp7FZfdKm4PFeQxML_MaAkKMEALw_wcB

    It is thin and runny though, not like the gel which I'll have to try.

    Quoted from vid1900:

    Right.
    The Works says Hypochlorite on the $4.98 bottle, I could not find the cheaper one.

    Here’s what my “The Works” label reads.
