When I had my citrus tree in the garden it would occasionally get Citrus Rust Mites and that would look like a black mold on the leaves and make the skins of the fruit feel tough and look dark in spots.
I'm not sure about the spelling, but the product that was recommended to me by a local nursery was Volick Oil Spray.
Why not take a few leaves to a local nursery to see if they can identify your problem and see what they recommend.
