I was the service manager at an Apple Authorized Service Provider and some rich fuckwit brought in his top-end MacBook Pro he bought a few weeks earlier that he’d spilled water all over. It was completely unresponsive and all the water indicator stickers were flagging, so he’d have to pay a large fee and he opted to just buy a new one. I had him sign a release form, I removed all the water indicator stickers, disassembled and carefully cleaned the entire thing and put it back together. Sent it in to Apple for a warranty replacement and they replaced the entire unit except the display and sent it back to me good as new. That was 10 years ago and I still use the device daily for 3D modeling and rendering and it’s still an absolute beast.
