I have an Apple wired (external) keyboard (model A1242). Some small amount of water was spilled on it, and the `Z`, `X`, `C`, `V`, `B`, `N`, `M`, and left `command` keys were rendered unresponsive. All other keys work without issue. I have spent days to sufficiently dry the keyboard, but with no luck.

``esc``F1``F2``F3``F4``F5``F6``F7``F8``F9``F10``F11``F12``⏏`  

````1``2``3``4``5``6``7``8``9``0``-``=``delete`  

`tab``Q``W``E``R``T``Y``U``I``O``P``[``]``\`  

`**\***caps``A``S``D``F``G``H``J``K``L``;``'``return`

`shift``**Z**``**X**``**C**``**V**``**B**``**N**``**M**``,``.``/``shift`  

`fn``ctrl``opt``**cmd**``cmd``opt``←``↕``→``

It's possible that I can [open up the keyboard](https://www.ifixit.com/Guide/Repairing+Apple+Wireless+Keyboard+without+destroying+it./30578) and [repair the traces](https://www.youtube.com/watch?v=REz928pgCII). I'd prefer to [wash the keyboard](https://www.youtube.com/watch?v=rabx240pooM), [in the dishwasher](https://www.youtube.com/watch?v=mdOF9k5awSM), or in a liquid bath, possibly [in alcohol](https://www.youtube.com/watch?v=RhfV4SxDEQU&feature=youtu.be&t=264), because that's much easier. But I don't know if the washing is generally safe, or if there's *some risk* for damage. I also don't know if washing would even do anything, since the corrosion may not dislodge/dissolve in a washing liquid.

**Question: Is washing/soaking safe, and what method would you recommend?**

N.B. [This answer on ifixit.com](https://www.ifixit.com/Answers/View/10904/Soaking+an+%22Al+unibody+MacBook%22+keyboard+in+Isopropyl+alcohol#answer10908) says that any liquid could dissolve the traces on the keyboard's plastic sheets (the key matrix)!! However, other people are *clearly soaking/washing* their keyboards in water without issue, so it seems possible. Is it a matter of luck/chance? Maybe there's no way to know if it's safe...?

**Further explanation:**

There are numerous internet sources saying that water contacting the internal plastic membrane can cause corrosion of the metal traces when the keyboard is electrically active. I have spent a few days drying the keyboard, even in the oven for a few hours at about 140 °F (60 °C).

There are also numerous sources showing that some models of wired keyboards can actually be cleaned in the dishwasher (without soap, other dishes, or heated dry), as long as they aren't electrically active (e.g. a battery). There are other sources saying that certain electronics, including keyboards, can be soaked/washed in very high concentration alcohol (rubbing alcohol and possibly ethanol, as long as it doesn't have other ingredients/adulterants). Acetone is bad, however, as it can dissolve adhesives and damage plastics.
