MacBook Pro Would't Turn On After Tea Spill. Help me

Just had a repair like this the other day, the person was using wipes with water in them to clean their keyboard, and the power key would not turn on the machine.

For oxidation issues, I suggest using DeoxIT D5, and a small soft bristle brush. As always when working with chemicals use gloves and caution.

A full shell replacement fixed the problem we had, after removing the old shell and taking a look under the film for the keyboard, it was apparent there was oxidation on the contacts for many of the keys.

There is a chance that this fix may work for you as well. There are many replacement parts available on the web that would work, they range anywhere from $40 and up depending on the state they are in.
