Is it possible to erase corrosion stain on laptop's cover? I dont really know if its corrosion itself or the painting just totally lost cause of a battery leak (i accidentally put a wireless keyboard with batteries uncovered on top of the laptop, the batteries were literally melting over it) Screen is fine. I've already clean the stain with white vinager and some isopropyl alcohol but the stain is still there making me think its not actually a stain but a hole on the laptop's cover painting itself. Its an ASUS the ones with K555 product code. Gray ones from like a couple of years ago.. anyway, do you think it would be safe after this? Can corrosion keep expanding and damaging my screen after i cleaned it still?
