Ok, have been leaving my scope out heaps over the last few months. We have no nuclear power plants or acid factory, but something is on my mirror and won't come off.

I have washed in detergent, sprayed with windex, rub softly and then hard with cotton buds, rubbed hard with a cloth and even rubbed my finger across the surface.

These marks are not on the surface, more part of it i reckon.

Do i need a recoat???
