What does acetone do to glass?

Antoni Worthers  Follow

Acetone is safe on glass, but let me add one important caveat. If there is a coating on the glass (anti-reflection, polarizer, IR-filter, etc.), you may need to read the instructions on the glass lens/surface before exposing it to acetone. Acetone can damage many polymer-based materials (cause them to crack, dissolve, or otherwise change their properties). This is especially true for some lenses like eye glasses, camera lenses, and specialized optics glass materials.

But in general, a glass surface by itself is perfectly safe in the presence of acetone, mineral oil, and most other organic solvents (like alcohols, toluene, and hexane).

Anything is dangerous if handled incorrectly. People drown in water and can die of oxygen toxicity.

I would say that acetone is generally not dangerous. I use it to clean lab equipment, and it's commonly used outside of a laboratory setting for removing nail polish. However, as I said, anything is dangerous if you handle it incorrectly. Acetone is quite flammable, so you should keep it away from flames or high temperatures. You also shouldn't drink it or get it in your eyes. (Hopefully, this should be obvious.) If you adhere to basic lab safety, then no, acetone is not dangerous.

However, acetone is dangerous to the environment, so please don't pour it down the sink.
