I've been here before to post about my alcohol-damaged keyboard. The first time it happened, I took the laptop directly to a MS Store and they replaced the inner deck for (essentially) free. The manager agreed she would have used rubbing alcohol the same way I did and judged the damage to be "not my fault." Going forward I only used alcohol on a q-tip to remove targeted grease smudges and whatnot.

Fast forward to the pandemic, I'm using my laptop at work where we're instructed to swab personal devices (phones, laptops, etc.) with provided alcohol wipes several times during a shift. I figured things would be okay, and they were for a while, but lo and behold it's started happening again. The black coating is peeling away from the keys and is bubbled fairly badly on one.

Support has offered me a free in-warranty exchange, but I've had terrible, and I mean TERRIBLE luck with refurbished devices from MS before. Lost my SP4 to battery bloat and the two successive replacements they sent were lemons. Frankly I am not willing to go through that again, especially with a $2k laptop. I know for sure the device I have now functions as it should. Is there ANY way I can ask for ONLY the key deck to be replaced (I don't remember what it's called, sorry) when going through MS Support? They designed this laptop for modular repairs, but somehow don't offer them.
