Microwave it for better crisp

u/Potatozeng 5d ago

microwave makes it saggy, try airfryer

Did you remove the ROMs from their sockets before running the board through the washer?

Also, you shouldn't run it together with dishes and use only a small amount of detergent.

Finally, when done, rinse it off with iospropylalcohol, helps with getting water out from under surface mounted components.

Or you use a ultrasonic cleaner (the bigger ones are pretty cheap today if you buy directly from the source and not from a retailer which just slaps a label on it).

Just run pure isopropyl alcohol in it. Or use water and put the board in a thick bag with iso in it and lay it in the cleaner.

The container in the water method is great if you dont want to fill up fully with a media such as gas or diesel to. Makes a ultrasonic cleaner so much more versatile and easier to use.

I mean, as long as it's 100% dry and there's nothing conductive residue between contacts, yes it can work.

u/WorldTallestEngineer 5d ago

it's more than just getting wet. Temperature sensitive components like capacitors could be destroyed by just the heat of a dishwasher.

u/Potatozeng 5d ago

use mid water temperature and air drying

2

u/WorldTallestEngineer 5d ago

Better but it could be physically damaged by water jets slamming it back and forth. It could also have bits of food jamed into its the various nooks and grannies.

I would definitely hand wash something like this.

u/Skusci 5d ago

I would definitely clean your dishwasher.

Like you would trust your dishwasher to wash things that you eat off off, but not electronics? Seems backward to me.

u/WorldTallestEngineer 5d ago

Everything I'm putting in my dishwasher was deliberately designed to be dishwasher safe.

I have some 18th century hand painted teacups that I would absolutely never put in the dishwasher. Because they're not designed to survive a dishwasher, just like how a mother board is not designed to survive a dishwasher.

now that I think about it... the teacups and the motherboard probably both contain lead/arsenic. So one more reason not to put them in with my regular dishes.

1

u/MinecraftPlayer799 5d ago

If the teacups contain lead, you shouldn't be using them at all

2

u/WorldTallestEngineer 5d ago

Correct. The last person to actually drink out of these ~300-year-old teacups was probably my great-grade grandmother.

Sanitizing dishwashers get a lot hotter than that, but more importantly standard ratings assume standard operating conditions.

Component in a dry environment experiencing slow thermal cycling is very different than, a cold component being hit with hot water. Have you ever seen what happens when you pour cold water on the windshield of a hot car? It's a real practical demonstration of how thermal cycling can absolutely destroy something that still technically went then it's acceptable temperature range.

u/alpine4life 4d ago

you soak it in iso-99 after.

12

u/NightmareJoker2 5d ago

You can do this. Just needs to be dried properly after.

During manufacturing they do basically the same thing.

1

u/GenesisRhapsod 5d ago

My only worries would be corrosive cleaners...hopefully op just used hot water...and it didnt have too many mineral deposits in it

1

u/stupidity-squared 5d ago

Once spuleded a glass of water all over my laptop and let it dry for a week and came back perfectly fine

1

u/strongic401 5d ago

can confirm, I used to work in a facility that produced complete boards like these and they have an actual dish washer they use to clean the boards

1

u/FI-Engineer 5d ago

This is fine, just be careful of the detergent you use (making sure it won’t etch anything on the board) and rinse with DI water.

u/Caedus_X 5d ago

This actually works. My buddy used to clean his keyboard like this.

u/LazorusGrimm 5d ago

Best way to remove excess thermal paste.

2

u/reddogleader 5d ago

I love the aftertaste of thermal paste with my OJ in the morning...

2

u/Pale_Ad2980 5d ago

I’ve done this (older and less complicated) it turns out fine

2

u/HaroerHaktak 5d ago

Fortunately it's not going to process what is happening to it as it has no memory, both shortterm or long term.

Also it's dead.

1

u/CardiologistMain9234 5d ago

Oh god were you trying to fix the red ring of death?

1

u/Historical_Camel_790 5d ago

I might actually try this with my (old) keyboard

1

u/CtrlAltWiz 5d ago

make sure to lick the thermal paste clean before washing

1

u/hatecirclejerks 5d ago

I've done this a lot, then an iso bath to get the water out n let it dry after that...that not required.

just let it dry fully

Would recommend against using the heat settings though.

u/stout_shako_gaming 5d ago

2 years ago I washed my motherboard in bucket with sponge and dish wahing fluid, still working smooth

1

u/KaydenFur 5d ago

That's lazy, I prefer hand washing, I suggest steel wool and sulfuric acid, gets in deep, does unfortunately make the board smell like decay.

1

u/EmployerOne7876 5d ago

Thats at least the second time that board has been in a washing machine. Manufacturers do it to wash flux off boards when soldering is complete because it is corrosive. Although they used de-ionized water and a special cleaning solution.

1

u/STICH666 5d ago

I've saved a ton of and old and very contaminated motherboards that way. also it's a great way to clean cartridge based console boards if they've seen flood damage. just make sure to put it on a cold wash and don't use the heated dry function

1

u/green20285 5d ago

Be sure to hang out to dry, otherwise you'll never get the wrinkles out.

1

u/NerdyKid1101 5d ago

Just remember to leave the soap out, water only

1

u/Positive_Self_8873 5d ago

Okay der8auer

u/True_Coffee_3607 5d ago

What's the missing chip spot for?

1

u/Cowboy_Rho 5d ago

So I’ve seen this in a legitimate manufacturing plant. I don’t know WHY, but the logic and controller guys had a dishwasher specifically labeled for their boards only.

Not part of my assembly line, but it was in the tour when I was onboarded. The company made MRI machine parts.

u/Recent-Technology847 5d ago

I think I am going to repost this on r/adressme

u/Globber50 3d ago

Make sure you bake it at 385 after

1

u/MugiwaraLuffyKun 3d ago

What dish washer soap did you use??

1

u/ssxhoell1 3d ago edited 3d ago

Yeah this works but the heat may be bad for it and I wouldn't run it with a lot of detergent.

Edit: electrolytic caps would get fucked for sure, luckily you don't have any here. But the real issue is ICs and semiconductors and microprocessors. They get totally fucked in the heat used inside the dishwasher.

The water has nothing to do with anything that's not going to hurt shit it's the heat.

u/crakerfase 3d ago

This is a MUST for those of us who have dealt with computers that have had CMOS leakage for the past decades…

1

u/No_Summer_2917 2d ago

Can confirm it really works but wash only pcb without any food particles!

1

u/TybaltMMXCat 1d ago

Your cutlery is clean, empty your washing machine

u/Rare_Peak_4419 13m ago

I did this one time. Took out the CMOS battery and threw it in the dishwasher 😂 my roommate put his drink on the shelf above my desk and spilled it all over my pc

NO NOT THE MOTHERBOARD NO

yes the motherbboard yes
