hmmm tried to "manually" spin the cleaning disk (power of) check the position required for reading head, remove disk, gently move head, replace disk and spin disk manually again, carefull when positioning reader-head though, it might break if you are unlucky.

or perhaps 100% manually, use a soft lint-free tissue and GENTLY brush the lens. we are talking a corner of tissue merely touching...
