(1) Use: Ethanol alcohol (Alcohol concentration 76 .9 ~ 81.4 vol)

 


(2) Do Not Use: High alcohol concentrated ethanol alcohol including:
- Anhydrous Ethanol alcohol (Alcohol concentration ≧99.5 vol %),
- Ethanol / Ethyl alcohol (Alcohol concentration >81.4 vol %) etc.

 

 

 

(3) Chemicals cannot be used for disinfecting and cleaning:

Into which category do hand sanitisers fall into? They seem to do an excellent job on keyboards.

Have you tried a damp microfiber cloth? I also use whoosh screen cleaners with the microfiber cloth that comes with the cleaner. 

 

With my keyboard which is not a laptop, I take the keys off about once a year and give them a clean with soap and water.

Does this mean 81% ethanol is OK but 82% is not?





Sometimes I just sit and think. Other times I just sit.

I have used this product for 10+ years. After vacuuming potato chip crumbs from below the keys.

Just to be clear, I use it all over my laptop - not just on the screen.

Would https://www.jaycar.co.nz/1l-kleanitize-70-ipa-isopropyl-rubbing-alcohol/p/NA1071 be any good? I got the stuff because the Apple polishing cloth can be used to clean screens with it, not sure about the laptop though.

That is _quite_ the list of dos and don'ts! No compressed air, no vacuuming, use specific alcohol concentrations of only 76.9 - 81.4, and disinfect up to 5 times per day!? At least some of that guidance seems to be directed to covid (I would guess that is where the minimum IPA concentration comes from).

Let's just say my experience with Fujitsu hasn't been great (the laptop is brilliant, though!), but I've been informed by a trustworthy source I'm not an isolated case.

 

I would ask their help desk for recommended products, but that forms part of the bad experience.

I'm sorry, you've voided your warranty because you only disinfected twice a day using 81.5% IPA instead of the specified 81.4% five times...
