necdetdoni,

Your connector from the Disk Controller board (infront of the middle C key when you open your keyboard) to the mother board is probably loose and needs to be pushed in.

As for cleaning, you can spray any detergent onto a clean cloth (that is alcohol free) and gentley rub on affected parts. Circular motions would be best.

Thanks,
