Supposing that someone spilled soy sauce by accident on a laptop computer’s LCD screen (don’t ask how,) is the soy sauce’s salt strong enough to eat into the screen and corrode through the outer membrane? What would that do then?
NOT asking for a friend.
Just wipe it off. It’ll be fine. Unless’un it leaked into the innards and hit a circuit board. Salt water is a good conductor and is likely to short out something.
“Light” Japanese soy sauce is saltier than regular Japanese soy sauce, which is saltier than regular Chinese (“light”) soy sauce, which is saltier than Chinese “dark” soy sauce. And I’ve read about a clear soy sauce from China also, but have no idea about its content.
FWIW.
Yeah, it seems odd. You need “reduced salt” soy rather then light to get the sodium down. My wife’s favorite Thai soy sauce is thin, nearly clear and extremely salty. I like the Kikkoman reduced salt version.
In a sort of related incident, I wiped the screen of a game tablet at Buffalo Wild Wings with their wet naps and it killed the screen for about 15 minutes before it would respond to a finger touch.

You seem to be asking what might have caused damage that you can actually see to have taken place. One possibility is that whatever was used to try to clean up a spill may have damaged the plastic front layer of an LCD screen.
I have seen solvent-based glass cleaning solutions used on plastic computer screens in error (possibly alcohol or acetone based wipes), and these caused streaks of cloudiness in the plastic surface. There is no remedy short of replacing the screen.
Soy sauce isn’t likely to corrode plastic, regardless how salty.
Interesting, thanks. I’m not sure my LCD screen is “plastic,” it is the soft, pliable type of LCD screen.
But also, apparently, the Internet says a vinegar solution can be used to clean an LCD screen, so it must be somewhat corrosion-resistant, vinegar being acidic. Wonder if there is a difference between how acid affects a surface, and salt affects it? They’re both corrosive but in different ways?
That sounds exactly like plastic.
The acid in vinegar and the salt in Soy Sauce should neither be powerful enough to etch common plastics or glass used in display screens. Organic solvents such as alcohol, acetone, gasoline, benzene etc will cloud some plastics.
What kind of damage are you actually looking at? Can you please describe the damage you are seeing? Photos would be even better.
I am wondering at this point if your’re looking at some sort of soft protective packaging film that was intended to be peeled off before use. I mean, don’t try peeling it off yet - but if you can provide more description of what you’re seeing, it will help.
