Re: Permanent stain on sensor

As mentioned, you have little to lose at this point. My thoughts are: from the image you posted, it looks to me like the "stain" is on the outside, given the shape of it. I suspect this is a mineral residue. I would try a carefully placed spot of white vinegar over it. Let sit. Remove with the lightest touch of tissue paper JUST touching the fluid (like blotting paper). If it was/is calcium residue, (my suspicion), then it should be sucked away with the tissue.

IF it does prove successful, a follow up wet clean may be in order.

Let us know how it turns out.
