has anybody used this kind of aerosol spray to clean a pc? my friend just told me he uses some kind of contact cleaner to clean his mining machine WHILE THE MACHINE IS STILL PLUGGED IN AND RUNNING.

 

it's not just air that's being blown out of the can. it's got some kind of fast-evaporating liquid or something.

 

thanks,

That seems like a terrible idea. 

Is it plugged in? Is it turned on? Are you sure? No, really.

Contact cleaners are for removing oxides on electrical contact points and connectors, not for general cleaning. They're fairly harsh solvents and should only be used when needed on corroded connectors, not all the time on everything. I believe contact cleaners are usually non-conductive, which is the only reason your friend's computer isn't dead if he actually sprays it down while running.

¯\_(ツ)_/¯

he sent me this picture, and said this is what he uses to clean his asic machines, WHILE THEY ARE STILL PLUGGED IN AND RUNNING, LIVE.

Will HE replace any parts that fail as a result of his recommendations...??

I frequently edit any posts you may quote; please check for additional info. added.

 

Did you test boot it, before you built in into the case?

WHY NOT...?!

most likely, NOT.

 

and that's how i ended up here asking the professionals for their professional opinions.

Oh boy, that's not even contact cleaner, that's a Chinese knock-off of Chemsearch Lexite, which is a degreaser.

¯\_(ツ)_/¯

What 'faults' are you looking to resolve by this method?  Typically, a machine should be powered down & the parts that need cleaning removed, cleaned & reinstalled.

CHCMSEARCH

It's all just chcmicals in the end...

 

 

 

The legit stuff is actually a thing.

If that is exactly the same it is what it can be used for, seems somewhat odd that his miner would be sucking air that needs a strong solvent cleaner like that regularly...   but never tried so maybe he knows something we don't.

 

Seems more like a mix of overkill, with laziness, with tightarsed downtime means less profits.

 

I personally think it could be slightly risky as it mentions damaging some plastics and if it it's a knock off mix, I would want to use on components on an absolutely needed basis and where you can visibly confirm no issues or damage and that it has worked, not randomly sprayed into stuff.

the website says: "DIELECTRIC CONSTANT 5,000V" but i don't see anywhere mentioning that this spray can be used on machines that are plugged in and powered up.

 

ya, he said he didn't want to lose 15min of booting up.

how much can you lose in 15min with aisc anyways??
