I need some advise or help here. Last night, my wireless battery was leak, it drop on my macbook aluminium. After clean using tissue, it left marked with white mark on the part which on palm rest. Anyone know how to clean it. I think the battery leak was chemical, so might be interaction between aluminium and that chemical so i cannot clean that spot. Anyone has experience handle this things ??

Already used the cleaner for the screen. It not work also make it even worse. After a while the white colour at that spot appear.

I was apply autosol on that, i work and the spot more less than before..
