    Thanks for the inputs. I had some partial success with a
    warm vinegar soak (no visible effect) followed by
    an ice water ultrasonic bath (bigger dots gone).

    At the suggestion of someone who paints upon
    plastics, I soaked the glasses overnite in isopropyl
    alcohol (50% is what I found at the store) and
    next morning they cleaned up like magic. Guess it
    loosened up the attachment just enuf.

    I splattered my plastic lens glasses with polyurethane varnish and a couple of days later soaked them overnight in regular over the counter undiluted isopropyl alcohol (70%) and they cleaned off beautifully the next morning. Thank you so much!
