Re: Permanent stain on sensor

You've probably got nothing to lose by trying David's suggestion of trying again with water, as long as you use a tiny amount.  My guess however is that some of the water got between the layers of the sensor stack while it was immersed, in which case no amount of work on the surface will help.
