pollution on corrector plate

Hi Everyone,

I have some spots on my LX 200 ACF corrector plate, they only show up when there is moisture applied, such as breathing on it. When there is no moisture, the plate is spotless (literaly ). As i live in a relatively clean part of the country in terms of atmospheric polutants, my only thought that it could be is woodfire smoke settling on the plate from a dewy evening.
I now use a dew shield to help this situation.

I would like to hear from others in relation to if you have experienced such deposits on a observing night when there were fires burning (fires to warm houses), and wheather it left any permanent marks on the corrector plate, and if so how were they removed. I bought the bintel solution and tried that, it reduced the spots slightly but they are still there. i have gone over it twice.

My concern is image quality.

I have attached 2 examples of each situation - no moisture and with moisture (breath). And i see the streaks - need to clean that up .

Thanks for looking.

Josh
