A bag of Soap leaked in my Backpack, and the charger side(left) of my mac bock was entirely sunk in the soap (1-2cm), even though it was in a seperate bag. Now after i dried it and tried to turn it on or charge it, it neither turns on or charges (The LED of the T Style Charger doesnt turn on at all). Is there anything I can try or I should do ? The reason it doesnt turn on might be because I did not charge it for a week.

At this point you need to open the system to inspect the internals for any soap residue. Using distilled water (not tap!) and some cotton swabs to clean out what you find.
