I second the Novus suggestion. I use it on my acrylic/plexi windscreens
and face shields all the time.
If you have scratches that you can feel with your fingernail, start with
#3 , rub till dry and "not catchy" then go to #2 and stay there until
all visible scratches are gone or "good enough". #1 is pretty much just
a finishing polish and anti-stat, not really abrasive.
From then on, clean meters by spraying #1 onto a clean cotton or
microfiber cloth, then polishing to dry.
Expensive for all 3 grades and *lots* of rubbing required, but perfect
results with a little practice and also useful for car gauge overlays,
taillight and headlight lenses, aquariums, etc. Pretty much any
gloss-finish plastic.
Once scratches are removed, Plexus (different product) also works well
for cleaning, polish and antistat, and is available in a spray can from
most motorcycle shops.
Too much info, but one more: DON'T use paper or cheap, plastic-fiber
towelling for this or other polishing jobs. Cotton and (better!)
microfiber rule here.
