Part of the components covered by a sticker

Inside the 13" MacBook Pro with Retina display Late 2013 there is a part close to the battery with some chips that are covered with a sticker and a warning message. I guess those are related to the battery but could not find anything specific.

After a liquid spill I have cleaned the logic board but the battery is not working and I suspect it could be because it is very sticky on that part (it was Coca Cola, terrible)

Is it safe to clean that part with alcohol as I did with the rest of the components or better not to touch it in any way?

Answer this question I have this problem too

Is this a good question?

Isopropyl alcohol is safe to use on most PCBs. Don't get it on any mechanical parts though, like optical or hard drives, or fans. Use 70-99% isopropyl alcohol and use a swab to dab it on, then if debris needs to be cleaned off, use a soft cloth. Once the debris is clear, dab on a little bit of alcohol over the surfaces in question, then let it evaporate completely.

Don't get anhydrous alcohol, as pure chemicals can be dangerous and finicky to work with.

Thank you for the tips. I just checked the battery logic board and one chip looks damaged, I'll bring it to the Apple Store to replace the battery.
