Just a bit of blast from the past trivia but the user manual that came with my Tasco 60mm Refractor back in the 70's recommended the use of Chloroform to clean the objective .. which you could get from the Chemist back then.

Chloroform is basically bleach and thinners. You can find both recipes and process on YouTube. It’s a very harsh chemical, my guess, it’d knock of modern coatings. I’d not use it, however it’s good for quietening macro photography subjects, even then, cooling the subject works as well.
