MacBook Air M2 Liquid Damage

There is no way to clean any parts individually; the entire top case woud be replaced.

You didn't mention it, but where you took your laptop to was that Apple or an Apple Authorized Service Provider? Per chance did you get an AppleCare+ plan when you purchased this laptop?

FWIW. I have a 2020 MacBook Pro. After having it about a month, plain water was accidentally spilled on it. Doing something similar to what you did, I immediately powered it off, wiped up as much water as I could and turned it upside down to allow any water that may have worked its way inside to drain out. I left it alone for about 3-4 days, before I tried powering it back up again. I was greeted with what looked like a distorted display. Obviously (to me), liquid got inside and left conductive residue. Having an AppleCare+ plan, I elected to contact Apple Support and shipped the laptop to them (I don't have any Apple Stores near me) to be examined. They found that they needed to replace the logic board, touch pad, & the display. With AppleCare+ it was covered and I paid a much reduced price for the repair. My point is, even plain water can cause this much damage. When you add other things like sugar, it can even make things worse.

Well, we are not Apple employees, so you may want to check with Apple,but that is what we've understood. It would also be good to have Apple inspect the device; water damage can slowly be getting worse over time.

Yeap the service was Apple Authorized Service Provider and I don't have AppleCare+, just warranty that is not include damages by user mistake. Thank you for your message I get it. But they already checked and inspect the device. The problem is only sticky buttons. I am using this computer even right now.

Make sure you have a current data backup. Liquid damage is often ongoing due to corrosion.
