Hello there,
This not really a rifle scope, but I thought the question is so similar that it is arguably useful for the audience. I have a microscope. It has a central main objective. It seems the previous owner had an accident and sprayed some particles onto the surface of the bottom lens: I have tried cleaning with isopropyl alcohol, acetone and a polyurethane paint solvent. It didn't help. What is your advice? Thank you for your time. Kind regards, Marius Jonsson

Wow, that's a tough one. I can think of various solvents to try (such as MEK...Methyl Ethyl Ketone) , but have NO idea how they may affect the glass or coatings. I guess I'd contact the manufacturer of the microscope for their advice. What a shame to have to deal with that mess. Good luck.

It looks like what ever they sprayed on to it ate into the coatings to me.

This is a lost cause, I believe.

If acetone won't clean it, anything that might will probably etch the glass/coatings. Any idea what the substance was?

Reaction time is a factor...
