What is BEST SPRAY for Computer Cleaning / Electronic Parts

This is my experience with NIKAVI - Dries super fast (in seconds) & removes all dirt/corrosion and you can use a blow-dryer too. I have used it on my Monitors (terminals); RAM Slots; PCB too; Logitech Mechanical keyboard & Mouse; plus on my water cooling loop.
AND ITS DAMM CHEAP - just Rs 263 for 400 ml
NIKAVI Spray

Other option I considered was WD40 Specialist - But price was a whopping Rs 2348 for just 325 ml.
WD40 Specialist

Do you have other recommendations that are proven SAFE and reasonably priced.

What's the difference between this and a compressed air can?

I suppose a compressed air can (as any blow-dryer) will do only a certain part of the job - whereas using a chemical spray will also ensure a better job of removing 'corrosion, stubborn dirt/dust particles' and re-juvenating the connectivity between your contact points.
 
Where do you get compressed air can for cheap. They are exorbitant priced everywhere.

For the time being i use just the blower side of vaccum cleaner. The force of air is not much but it gets most of the job done pretty good.

And if the surface can be accessed then i use IPA to clean the surface. Never had any issues with IPA. Old toothbrush + IPA is my go to solution for all electronics cleanup.
 
+1 for IPA.

This is my stock that I use for resin 3D printing as well as cleaning just about anything electronic.

Emplura is the slightly lower quality line intended for lab work, but still quite high quality and cost me around 1950 for 2.5 litres. I go for this as it can be further diluted if your application demands. Available from nearby lab supplies place.

I always keep it handy in a small spray bottle.

Any idea what the chemical is? I didn't see anything informative on the can.

Or can we assume it's just diluted IPA in a compressed air can?

You can't. This is why I use a battery-operated blower like the one in this comparison. The second gen of that blower which even has a vacuum seems to be going for song right now.

Still too expensive. My EUREKA FORBES vaccum cleaner cost me 8k that i bought last year. The blower is okay type.

But i do have an old Eureka forbes at home in Kolkata. Old style , big boxy style one and makes an airplane takeoff type noise. But damn that machine is one heck of powerful one. Both the suction and blower is way more powerful than the puny machines available today.

Sincerely no idea about the composition (i.e what chemical is used) and they should have mentioned it...... BUT IT WORKS like a charm.

That's my go to, especially screens as you don't want anything water based, like Colin etc. Especially don't let maids near electronics.

have been stalling cleaning the desktops in dad's office. how many cans do you think i'll need for around 20 desktops?
Click to expand...
I think just 1-2 cans of NIKAVI can do the job for 20 desktops.

NOTE HOWEVER:
BEFORE YOU USE NIKAVI or any Other Solution (even IPA - if needed) - Follow the Steps Below
1. Use a Vacuum Cleaner / Blower to clean all visible dust
2. Remove RAMs (you can spray on RAM and the Slots) - then after 5-10 mins Clean edges with a Satin Cloth or Good Tissue Paper (blow dry the RAMs too later)
3. Spray on all other contacts of PC - where necessary disconnect & clean too (including USB Slots).
4. Use a Cloth or Tissue Paper to REALLY Clean off Dirt from PC/Cables etc
4. Lastly - USE A BLOW DRYER ..... For 100% satisfaction of having DRIED out All Components

Simple Solutions - I have suggested NIKAVI as it Dries Extremely FAST.

What cloth do you use to clean the screen?

I have some dirt stuck in laptop screen. But not sure what to use. I have some high GSM microfiber cloth (400+ GSM which I use for car cleaning). But they seem too coarse to use on a delicate screen.

The cloth that is given in spectacle boxes seem to be best suited for cleaning screens. But that is a tiny bit of cloth. Not able to find anything larger but of similar material.

I use either a microfibre towel or the ones from specs cases, my preference is the latter.

Plenty of these available on Amazon, search for microfiber cloths. The quality might vary, some of them leave lint. Decathlon sells washable ones for 50.
