When used properly, in a clean room with proper ventilation and safety procedures, by someone with experience, it is certainly fine.

High-purity acetone in a lab or professional shop is not the same as high-purity acetone on the kitchen counter or in the bathroom sink. I would not recommend using it to someone with no such experience.

Also, I was always taught in the lab that the use of acetone on coated glass should be done briefly and seldom unless it is known that the coating on that specific lens will tolerate it. I can't speak for the lens in question, but many coatings on older microscopes and telescopes can and will be eaten over time by acetone... along with plastics, lens cement in microscopes, and your gloves.
