Chosen Solution

I’ve opened it up and definitely see some corrosion (also it doesn’t turn on). I got this advice from a Apple discussion board post (https://discussions.apple.com/thread/250...): “Put a little bit of Isopropyl Alcohol onto the corrosion and let it sit a minute or two before using the toothbrush to very gently brush it clean. Do not press on the toothbrush or you will likely break the very small and delicate surface mount components from the board. Blow some compressed air across the area to push out any alcohol which may be trapped beneath the components. Let the board sit an hour to let any remaining alcohol evaporate. Make sure to disconnect the battery from the Logic Board before performing this procedure.” Anything to add? Also, should I take out the board and clean both sides of it?

Hi @idikiy , Here’s the ifixit Electronics Water Damage guide which details what needs to be done with water damaged electronics. Be sure to use Isopropyl Alcohol 99%+ (available from electronics parts stores) and not “rubbing alcohol” as most only contain 70% IPA or less, can contain additives and are not as effective at removing the corrosion. Usually IPA 90% and over is suitable Remove any shields that may be covering any components as the water may have got in under them as well and brushing may be required to remove any corrosion that may be there. Also disconnect and clean any cable ends, cable connectors etc It would be wise to check both sides of the board just to be sure. It may be a pain to completely disassemble everything and check, but in the long run it may be better to make sure that everything was cleaned etc and not just assume that all is OK Here are the ifixit MacBook Pro 13" Touch Bar 2016 Repair guides that may help.
