Got hard water spots on my HPS bulb

Well I had some water leak onto some HPS bulbs I was storing. They have some hard water spots on them and are pretty hazed over. Any suggestions on how to clean them? I was going to treat them like you would a glass window. Put some vinegar on them and use a sponge to see if they come off.

sounds good!

vinegar diluted with water will remove the hard water stains. I used to be an auto detailer and charge hundreds to remove water spots that took me all of a half hr to remove. trade secrets pays the bills.

and now millions of us know this trade secret

Good thing you no longer do it or you'd be out of business haha

heres another 1000.00 tip, denatured alcohol removes tree sap in seconds, SAFELY. I used to make 500.00+ removing sap from entire car paint finshes. wheel acid + paper towels soaked and placed on vehicle paint that has limestone/calcium deposits left from water dripping/seaping thru parking structure building blocks will revove the hard rock deposits that form. once again, safely w/no damage to paint, not too many people know these trade secrets.

and NEVER EVER buy a vehicle that was an auto show vehicle. trust me.
