I'm staying out of this one as far as good or bad, other than to say I personally couldn't even consider risking water on any of my machine/wood/cloth covered wires/motors/relays/etc. But that is just my choice for my stuff. I know too where I've heard people do it successfully.

Again, not a fan of water, but the dishwasher thing for PVC insulated harnesses etc....well....my first thought is, I don't want to eat off someone's plates ever when I hear they use their home dishwasher to wash grimy parts etc in it too.

ALTHOUGH, I would probably be more likely to risk grease/lead/flux ingestion than whatever NASTY stuff comes off of people's dirty hats when they tell me they use it as a washing machine for their favorite baseball cap. Lol.

And the score motor I would think...

Except people's virtual pinball machines! Those I recommend hosing out internally at least once a month

Bakelite composites have several materials that absorb water and can swell. I wouldn't recommend getting them wet personally; but a lot of my concern with that comes from years of industry imvolving phenolic/bakelite insulators for higher voltages than seen in a pinball typically. Still, a concern with swelling causing weakining etc???

In general (not necessarily full washing), I've always wondered how even scrubbing/using cleaners on cloth covered wires affects the varnish coating on the cloth. A number of years back, I used a little cleaner and light brush on a few extra nasty wire sections....but I had begun to be concerned about the damage by disturbing the old wires, so I no longer do any more than a little brush on the vacuum.

Good to hear it has worked well though!

Thank you for sharing your experience! Again, while I have heard some people say they had no problems, your not the first story I have read about disaster/ruined game either.....

That's why I'm only saying what I am concerned about...not arguing if someone wants to try it for the risk/reward.

As an extra note....again just me....if I was buying your game, and you told me you hosed it out.....I'd be a bit more concerned to double check it. Just something I was thinking about this afternoon.

I know I sound like a hypocrite since I started out in this thread trying to be totally neutral....but more and more I think about it, the less likely I would personally be to do it to something of mine unless absolutely necessary VS trash machine cuz of nasty or something.
