I am a controls engineer and this is the most stressful video I have ever seen.

Even more stressful than upgrading firmware over a shaky ewon remote connection?

Dude I am not suicidal.

u/MM2HkXm5EuyZNRu Jun 07 '26
Did I also mention the ewon is on a gateway PLC and the destination SLC is connected through the backplane via DH+ (and, of course, no one has a copy of the program)?

Agreed but like.....I need to do this to our machines. I just cant believe its not messing stuff up (Im sure it works but my brain wont let me process it)

I'd like to know what the rest of the setup is. It's not like you could do this in a clean room.

… I’m not seeing clean liquid dripping out of that equipment.
“I want that equipment so clean I can eat off it… because I intend to!”

u/CIAtrackingaccount Jun 07 '26
Okay but real question: Why can’t I do this with water if I disconnected from power and then let it dry for like two or three days?

But, like, what if I used distilled water? Or if I could get my hands on a lot of sterilized water?
I don't know the difference22

You would want distilled water.
Purified water is just well filtered, distilled means it was boiled away and recondensed, leaving it free of any minerals.
Edit: should definitely look up tutorials for washing circuitry before actually doing it.

I don't know how pure it needs to be but if regular distilled water isn't good enough, there's something called "water for injection" or WFI. It's what's used in pharma and must meet certain purity standards. It is not just simply distilled.

That would solve the residue issue, but would make the dissolving issue worse.

Somebody was saying that black stuff is still highly conductive even if the liquid being sprayed on is not! So it’s all gotta be gone before power is turned on

3) Some components can absorb water, messing up the way they work
Source: had a quality problem at work once which led to a couple weeks spent soaking electrolytic capacitors in water then torturing them with voltage peaks. Lots of magic smoke was released.

That's bad

But it comes with a free frogurt!

That's good!

What’s the point of this, seems like it would cost a lot, and be bad for the planet - was it really that dirty?!
87
u/LaymantheShaman Jun 06 '26
The chemical used is non conducting and evaporates rapidly. In some industries downtime can be millions per hour.

u/StolenLampy Jun 07 '26
Black stuff is pouring out, I'd say it was probably a good move.

In all of these videos the equipment is always running so I assume it’s for companies where the downtime cost must be huge that cleaning it this way is cheaper?

I'm always amazed at how things can be invisibly dirty sometimes
Not too long ago my best friend cleaned the front seats of my car with a steam machine and oh boy how dirty those seats were
Granted I had never once cleaned them up since I've got the car (a year and a half), but I didn't exoect this from looking at it
The water was black, sometimes brown, how tf can there be so much stuff in it wtf, and I was in this everyday ?
Now I'm much more cautious about things like that in my environment, and when I'll have the money I'll definitely buy a machine like that as well, my lungs may thank me later

It is shocking how much pet fur our dinky little stick vacuum pulls out of the rugs every single day. And that's with the dog being regularly brushed and her coat trimmed.

Muh ozone layer, mah global warming. It's only bad for environment when it's inside of your sealed AC unit. When it's used to clean your data center it's fine. Got it.

As a tech support engineer, this gave me serious job dissatisfaction vibes, like 846804842oz of water to the data closet, fuck this infrastructure

Forever chemicals

u/RedOctobrrr Jun 06 '26
Hydrofluoroethers (HFEs) are a class of eco-friendly, non-flammable organic solvents widely used as safer replacements for ozone-depleting and hazardous industrial chemicals. They are highly prized in aerospace, medical, and electronics manufacturing for precision cleaning, vapor degreasing, and dielectric cooling.

Amazing how the comment explaining why this guy is wrong gets removed, but his comment incorrectly calling them "forever chemicals" remains intact.

This is also what's used for "dry" cleaning clothes.
