I recently bought a used canon xl-1 off ebay and it works fine apart from one problem, there is dirt on the second layer of glass, the layer just before the final one, there doesn't seem to be any way of getting to it, i've tried unscrewing it, but it didn't help,

Has this happened to anyone else? or does anyone know to fix this?
