Use acetone......DON'T use on poly
Don't use acetone!
Use non-acetone nail polish remover.
(Works great on my pedicured pigges, as well.)

Warm soapy water, if that doesn't work then alcohol, preferably a nice single malt; enough of these and they won't notice the speckles and they will have a nice buzz to boot.
Be very careful.............smell at it and you will detect a heavy smell of acetone.....................
Use "Markaway" or any other good optical marking remover, that can also be used on Poly.
warm water and a careful finger nail
Ditto 10x - assuming it's latex paint, the fingernail approach works just fine, and no chemicals involved!
Lost and confused in an optical wonderland!
Denatured Alcohol. Regular rubbing alcohol is useless.
Any other alcohol is for drinking
Non-acetone nail polish remover probably contains ethyl acetate, in the same family as acetone (ketones), both capable of destroying polycarbonate, although probably safe on 1.67. I'd start with something milder like isopropyl alcohol, and then denatured alcohol (which may contain acetone), and acetone as a last resort (the last two on non-polycarbonate only).
Edit: A wise Optiboarder has informed me that the non-acetone nail polish removers are safe! A quick check of one brand showed ethanol as the solvent, which should be safe on all lenses. My recommendation is to check the MSDS sheets if you're not absolutely sure.

Experience is the hardest teacher. She gives the test before the lesson.
The Eliminator has never failed me in these occasions.
It is the strongest non-acetone optical ink remover I've ever used.
I keep using alcohol and the spots aren't going away, they just get blurrier
Yup. This.
( ALL OFF ) from OptiSource, it will remove tar from a poly lens or any lens for that matter without hurting it at all, and it smells gooood, expensive but it is worth it
Why not a one size fits all solution: Straight Ethanol, I can go to the liquor store and buy corn liquor 9.99 for a 1/5. The thing lasts forever and I use it in my special cleaning concoction.
Denatured Alcohol is similar to drinking alcohol, however NO SIN TAX. To prevent people from drinking it two methods are employed:
1. The alcohol is not distilled to a drinking purity. This alone would not prevent folks from buying denatured and further distilling, so that's where method 2 comes in.
2. Chemical additives to prevent drinking, aka poisoning.
It's all about the taxes, going to such lengths to prevent avoidance of a SIN TAX when the consequences are blindness or even death. I don't know of many products that purposely are poisoned to prevent folks from avoiding a tax. Mostly the denatured has methanol which can react over time in high concentrations with poly, and as mentioned may have acetone or other harmful chemicals that can react.
Denatured is a big unknown and I tell many to avoid it and just pony up the extra few bucks for "White Lightning", plus a little nip in your kool aid and you've got jungle juice. Me and the wifey paid a few months rent with jungle juice, in our hey day.
