My brand new Samsung LCD monitor was accidentally sprayed with paint primer (oil based?), which left four noticeable dots of paint. Samsung techs recomended only Windex or a 50/50 Windex/water solution, but these were no help. One 3D dot came off with my fingernail initially, but the rest seem melded to the screen. It's plastic, not glass, I'm told. Any ideas? Help!
Well if you use matching paint thinner, most will wreck that poly plastic LCD covering,
the only thinner made that is safe for plastics is
called "just paint thinner" as seen in WALMART.
do not us acetone, nor lacquer thinner or MEK .
ok?>
oil based paint thinner.
the correct name is Stoddard solvents.
and most spray paint is not what you said, at all.
most spray paints are lacquer types and will cause the paint to eat in to the plastic,
but if lucky real Paint thinner oil based may work some.
aka: mineral sprits. (start tiny spot, Q-tip)

Paint thinner is about the only thing that could be safe for most plastics. but as its dry that will not likely work.
try some extra virgin oil or penetrating oil and rub it into the dots.
if you can get it to take the oil then it will come loose.
but you may have plastic damage anyway where they melded.
there are some plastic cleaners intended for screen but they are pricey and may not work at all .
the thing I use most on all plastics is ammonia because the oils in human and the ph in ammonia are similar thus it attacks the human oils easily , paint maybe. I use it full strength all the time.
no scented kind though.
its what is in glass cleaner initially.

You need to buy a
special paint for metal with special additives that prevent rust. Make sure to also buy a primer that is compatible
with the paint you have selected. I
found you some great instructions that should help you out.
• Wipe
the wrought-iron bed frames with a rag that was dipped in mineral spirits. That
will help you to remove all traces of oil and grease from the frames.
• Scrape rusty
areas with a putty knife or scraping tool. Remove all loose rust scale. Rub the
surface with steel wool, too.
• Apply an oil-based primer. The primer needs to be designed for
use on metal surfaces such as wrought iron. Roll on the primer with a small
roller. Spread the primer with a paintbrush. Cover the whole surface with one
coat of primer.
• Paint the
bed frames with a finish paint that has a rust inhibitor within 24 hours of
priming them. That will help the primer and paint bond.
• Roll on the
paint in the same way you applied the primer. Use a paintbrush to make smooth,
sweeping strokes to distribute the paint. Switch to a paintbrush with synthetic
bristles if you decide to use a water-based paint.

Thanks for your suggestion, Coldcut. I tried some extra virgin oil, but it didn't seen to help. Maybe I'll hold it agains the dots longer when I try again later.
lestoil, full strength, cuts oil base paints.
