Question:

How to clean build up on glasses lense?

There is a clear coat of build up o my glasses lense. Not sure what it is but I can feel it when I scrape it with my finger. Looks like something froze on it haha best way to describe it I guess ha. Was thinking acetone but dont want to mess up the lense. Any ideas?

Answer:

Are you sure it's not the scratch coat or the antireflective coating peeling off? If so, take them back to wear you got them and have them make a new pair of lenses. You may not have bought the glasses knowing that was on there as some lenses (most now) come with a scratch coat already on the lenses. From your description that is what it sounds like. Otherwise, try a Mr. Clean Eraser if Dawn and water have not worked. You could try acetone but you have to stand by with water to get it off right away or it could cloud the lenses too.

Use a soft cloth or soap and water. Do not use acetone since most lenses there days are plastic. You could melt them just like finger nail polish melts with acetone.

Have you ever heard of an ammonia based product called "Windex" ? Other general purpose glass cleaners will also work.
