If you don't want oxidation under the insulation on the wire(s) and on any exposed metal parts, use common sense and don't wash your harness with water unless you have a method for completely evaporating/removing all the water.
Pretty simple, really. But if you want to take the easy, fast, shortcut way, by all means, use water as a cleaning medium.
Ok guys quick question I have this white residue on my harlem globetrotters harness after running 1 cycle with soap and another with just water.the wires are beautiful but all switches and metal parts have this terrible white residue everywhere should I ultrasonic clean them or run another cycle for the 3rd time

It just wipes off for the most part, but its a lot more work. I'm quite disappointed, I feel like I made it worse than it was before, and compromised the coating on the metal parts.
I think it may be caused by the dishwasher salt, or the detergent? Liquid or powder dishwasher detergents aren't common over here in The Netherlands, just those tabs, so that's what I used. Pots and pans cycle.
What do you think, should I get some powder or liquid detergent and try again, or leave it at this (and clean manually)?[quoted image][quoted image]
Me too
What did you do too fix
With that kind of corrosion on mechs, all I do is ultrasonic clean, then use a smaller stainless steel wire brush on them under running water. It makes a big difference, but of course they will not be like new. For that you would need to replace or re plate the parts.
Wire brushing mech parts is easy, but targets and switches would be tough to do without bending them and such. So be careful 
Quoted from koen12344:BTW I noticed the same residue on some of our pans as well, maybe its lime deposit.
Didn't see this part. Yes that is possible. I use a pail with reverse osmosis (purified) water for the final rinse of parts after first rinsing with running water. Try something like that and see if it helps.
Ok and they didnt look like this at all until I ran in the dishwasher.the wiring harness does look brand new now just have this white residue on all metal components now.and I'm ready to reinstall harness now sadly.
I ran my ball trough through the ultrasonic cleaner and it looks brand new now.so definitely gonna try that with the eos switchs.and hopefully it will clean all that crap off of them.
Quoted from RC_like_the_cola:EBD harness is in the dishwasher. Wish me luck. Tough to fit it all with the 3 drop banks.
Deop banks are one of the things I leave out.
But I tumble them.
Good luck! I had every piece of painters tape fall off mine the other day FYI 
Well nothing melted. One switch came apart. Forgot to zip tie one damn switch. Lost one coil wrapper which I knew was gonna happen as it is a replacement coil with paper wrapper. Didn't lose my labels, but they smeared a bit, so this is gonna be fun. 
That white oxide forms when you have different metals in contact while washing.
Don't leave those Black Oxide screws installed in any zinc plated parts
Don't leave Stainless screws installed in anything aluminum
If you forget and get white oxide, just toss in the tumbler overnight

Remember, don't put coil sleeves, flipper bushings , fiber yokes, or other garbage that you are going to throw away, in the dishwasher !
The dishwasher can't clean stuff that can't be blasted with water because it's out of reach.
Obviously, take your mechs apart, and put small parts in the silverware basket
Quoted from RCSP:I read every post. One thing I didn’t see is can you wash opto’s in the dishwasher?
You can.
Quoted from RCSP:you said you worked on a pin from Ohio. Did he ship the entire machine to you?
I don't usually want the whole pin, unless it's something rare that I would want to play.
Quoted from vid1900:That white oxide forms when you have different metals in contact while washing.
It's definitely something in the water. I got a lot of that also, I have well water with a lot of iron (rust).
Vid are the power boards ok for the dishwasher? Those large capacitors scare me.
These boards are out of Judge Dredd, after a dishwasher run they look a little sketchy. The green is discolored. The traces are exposed. Can also see the white oxide in the first pic. This was on the top rack of a newer Bosch dishwasher that has no heating element.
Thanks for the help and the tips vid1900

As long as there are no relays, or other open parts, you can wash them
Google "draining capacitor with resistor" if you want to drain any cap

The green is probably discolored from the high heat and flux used when those resistors were replaced - no big deal.
Any zinc plated part might have some white oxide that you don't notice until 30 years of grime is removed. That's normal.
But when you see bulb-like growths of it, that's normally when 2 dissimilar metals are touching when wet.
Hi there, looking to give it a go, maybe a stupid question but do you think you could get away with leaving LED bulbs in their holders? Thanks for your input

No, again dissimilar metals would probably do something bad
Besides, you want to scrub out 50 years of dust and crap
Quoted from TheLaw:Pretty lazy probably fall out and spend more time picking them up
Your right that is getting lazy

Ok makes sense, thankyou Sensi Vid1900 ☺️
Thanks for your honesty. I am torn between making it bueatiful or making it work. Lol maybe I'll just clean all contacts and fire it up rust and all just to see what happens. Thanks again.
Well I took the plunge and put my EM control board cloth wiring harness in the dishwasher. I was pleasantly surprised as it came out good. My only major issues were keeping coils from dangling down and my dry cycle wasn't long enough so cloth is still wet. I'm putting this in front of pellet stove over night to dry out. If it was summer and 80 instead of 20s I would put it in the sun.
20210226_223041 (resized).jpgTook the plunge last week, no regrets. Lost a couple aftermarket coil labels, no biggee. Drop target mech is ridiculously clean now (new targets installed). All the leaf switches look like brand new.

Looks great @pinzrfun. I had wished my brackets weren't all rust or I would have dishwasher them like yours. I'm just happy I can now identify wire colors now. Lol
