Just tried collodion on an old non-working webcam sensor and it took some of the bayer layer off, so maybe repeated applications would work...

But I found the easiest way was just to scrape it off with an old fashioned flat razor blade. Seemed to work very well and didn't scratch the surface- its to small to get a pic of though.

There is a chance that Collodion could be used - paint it on then when dry it could lift off the layer.

It can be hard to get hold of though.

Will give it a go with an old webcam and let you know.
