It's almost impossible to keep eyelash oils away from short eye relief eyepieces; if body oils aren't cleaned off the coatings the eyepiece will eventually become unuseable due to opacity of the coating.
I have an old Meade Research Grade Ortho in this condition; sometime when I'm feeling patient I'll disassemble it and try to strip the coating from the top lens to see if it can be rendered useable again.
