Alcohol maybe, but acetone NEVER !

Acetone is a VERY strong solvent - it is nail varnish remover. Designed to dissolve things. Used to soften resin etc.

Sorry, but only a complete fool would even consider acetone to clean a lens, unless they wanted to create a paperweight.

So is the largest manufacture of stock optics in the world a complete fool?

Using acetone to clean lenses is ubiquitous within the optics industry.

Quoting from above link:

"An important point to stress is that you should NEVER clean plastic optics or optics in plastic housings with Acetone because it will damage the plastic."

The recommendation in the above link is for optics elements and is true, meanwhile AiryDiscus is talking about lens and I totally agree with him.
