I did a debayering test on a dead CCD with "cleaner paint", I do not know if this is the right word in English (paint cleaning product on wall of city).
The microlenses are dissolved without rubbing in a few seconds but harmless on the matrix so I put product to unclog the pipes ( WC and kitchen room) and and it seems that the matrix is gone without rubbing, the electronics of this camera is dead so I can not testing, but Under the microscope (toy of my daughter) one sees well that it is no longer there.
I do not have any CCD to try again but may be an idea to consider if someone wants to do it, we never know!
