I recently bought a pair of GE Form 101FR Clamshell streetlights which were originally used on Wilshire Blvd. in Los Angles California. The problem I have is that the glass refractor for both fixtures looks really cloudy and dull instead of transparent/clear and shiny . They almost looks like they've either been acid etched or media blasted . Has anyone ever seen this or know how to remove it ? Whatever it is it's not like the usual "fog" I see on glass refractors which is usually caused by smoke or off-gassing from the gaskets .
Absolutely no idea, Tim, but it would be interesting to see a picture.
Hmm, if it's actually been etched you might have to try polishing it with a glass polishing compound.
That said, if the glass is still in good shape and it's just stubborn dirt, I've had good luck with Bar Keeper's Friend.
We've got some of that, I bought it years ago and it's still going strong.! 8)
I'll try to get a decent picture of one of the cloudy ones next to a good one .
