I have a 2020 MBP. A couple days ago, I had spilled some of my drink, which had a little bit of sugar in it, on the keyboard. Everything works, but my "=", "-", delete, return, and power keys are all sticking. I know with the power button, it (probably) won't be possible to take it off for cleaning, but for the rest, how do I go about taking these off? I know the larger keys, delete and return, probably have a silver bar underneath that makes it harder for removing. How should I remove the keys to clean the back of them?
