Spots in my Tube

I've just noticed that the inside of my SkyWatcher DOB is covered in spots. Probably about 5ml in size. It looks like it maybe the result of condensation after a dewey night. It doesn't wipe off either. Anyone had a similar experience and could you do anything about it? Probably more to the point should I bother doing anything about it. I'd hate the tube to rust and it be my fault
