I was hoping to restore my 10 yr old Persol Sunglasses and went to ChatGPT for help. It suggested Novus Duo Set, start with clean polish and if that doesn’t work, continue to fine scratch remover. I followed that instruction purchased and tried it. Yes, it worked well! I needed to apply the red bottle (Fine Scratch Remover) 4x to exfoliate/buff it all off. All the layer of white ashy residue that built up from skin contact AND scratches from being dropped and daily abuse. Some notes to consider: - the bottle states Not to use on eye glasses. I suspect this is related to likely scratching the lenses if not careful. I am replacing my lenses with another set, so I wasn’t concerned about micro-scratching lenses. Use caution if you keep your lenses in the frames while restoring. - I did not exfoliate everything on the inside of the earpiece. The screen printed info : brand, model#, color, size will not hold up if you are rubbing and buffing. I made this mistake and started to remove the text :( use caution if buffing around printed info. Scratch removal: Successfully removed mild scratches on frames Polishing ability: Buffed to shiny finish! Read more

It works, just need to keep applying until it clears. Read more

Works better than expected. Scratches aren’t completely gone but have improved significantly. I will say I did it a few times in one sitting to get these results. Very easy. Read more
