    Have you tried dipping the lens in lens bleach for a few moments? Usually, the combination of heat and the neutralizer removes hints of ink absorbed, and slight denting of the lens surface.

    boil a cup of water and then place the lens in the hot water, for a minute or two. this will work onplastic lens only.

    Or just hold the lens over the tint unit.

    That is the approach of the ones that can not afford a remover, furthermore dipping into hot neutalizer will ruin poycarbonate lenses, also some of the high index lenses.

    Really???
    You think if acetone didn't work that mark-away will??!!
    If acetone doesn't remove it, ummm markaway isn't likely to do it. Chris seems so sure. I'd make him or them give you a money back guarantee & have them pay the overseas return shipping when it doesn't work.

    Wow..................what a little nasty post. Have to respond.

    Acetone is the best cure for thousands of problems, however it has also just about the highest evaporation rate of any toxic solvent and you are breathing its fumes as soon as you remove the cap of the bottle. Then you work with it and the ways of entry are not only your breathing it but it is also absorbed through the skin. Ever had an acetone high ?

    These days we are all looking for products that at least do not get into any evaporation stage when not heated and still do the job as well.

    And for the last part, in the 30 years in this type of business with all the exports we do to overseas, I never had to give back any money as you suggest.

    I just think it's good to protect yourself. He's is in Pakistan!! So, if the product wasn't any better as you suggested, even with a money back guarantee, it'd cost him $60 to $90ish for him to ship it back to the company & have the package tracked.
    The issue was never breathing or skin absorption. It was that acetone wasn't getting it removed & you said mark-away worked like a charm. (works better? I assume you mean).

    Wasn't trying to be mean.

    Chris, Are you saying your chemical removes markings better than acetone??

    Please don't ship that poor guy in Pakistan your chemical unless you really believe it'll work better. Gosh, that's like $30/$50 for the bottle of solution, I'm guessing another $30+ ish shipping (assuming your company get's a deal on overseas shipping).

    I believe there may be different levels/strengths of acetone. Make sure you're using the strongest one. I usually get mine from a hardware store but sometimes you can get something stronger from a pharmacy, but it's not cheap.

    What do these impressions look like? Are your lenses brown, but where the old markings were is it now clear? Send a pic if you'd like, but if it's a clear void where the old markings use to be & the rest of the lens is brownish, those lenses are probably done. Bye bye. I would guess the markings don't really show when on the face, probably more just when they are laying on a piece of white paper being scrutinized. Use 'em for charity or people on a mega type budget.

    Since these lenses are photo brown, they are glass. I would also assume they were tempered. If they were tempered with the marks still on/partially on they are embedded into the surface. No chemical will take that off. You could attempt a heat re-temper ( not chem-temper). Good luck!

    Toast, History, Try the strongest acetone or maybe naptha (lighter fluid). But if it's a place where the color is actually missing then it's not a residual mark that can be removed. Like I said, use 'em for charity. Try to write 'em off as a loss, ......???

    Back in the day we kept a small jar of glass lens polishing compound in the office. When we had marks on a lens surface that acetone wouldn't remove we moistened the eraser on a pencil, dipped it into the polishing compound, got the lens nice and wet and rubbed it until the mark disappeared. Worked *like a charm* (in this case meaning it worked great).
