How do you clean your eyeglasses?

I only use a cleaning cloth. But the trick is running the glasses under warm water first, otherwise they will get scratched. I wrecked my last pair of glasses within 6 months because of using my sleeve, napkins or anything but the cleaning cloths. They seemed to just smudge so I rubbed harder and harder. They got so scratched they were actually cloudy.
I just got new ones last week and the optician said to get them really wet then use the cleaning cloth only, rubbing them while dry is what creates lots of teeny tiny scratches.

I use the eyeglass cleaning kit I picked up at Costco. It had two bottles of liquid cleaner, two cloths, an empty travel bottle to fill with solution and a keychain tool to fix eye ware. You can refill the liquid bottles for free at Costco. The kit cost $6.00.

i use the pre-moistened foil-wrapped lens cleaners from Pearl Vision or Bausch & Lomb or the cheapies from Walmart, whichever is more convenient when I'm out. They've definitely saved my lenses so I don't mind spending a bit more.

I have learned a few new things about the correct way to clean my glasses!

Liquid hand soap, running warm water and I dry them on a clean towel.

I tell you, the timing of the peas always amazes me! Just last night I was trying to clean my glasses, and there were all these little dots all over them that wouldn't come off (they looked like grease splatters, but they wouldn't come off) so DH got out his ultrasonic cleaner that we use to clean misc things like jewelry, and we popped them in for about 5 minutes, and they are amazingly clean, even the nose pieces!

Other than that we buy the lens cleaner and cloths at Costco.

The ultra sonic cleaners are awesome! I use the one at the office daily when people bring in old, nasty frames to be repaired. These things are so gross and are often seem to be being held together just by dead skin cell black and green sludge all over the nose pads. I pop those suckers in the ultra sonic cleaner for a few mins and the caked on sludge just falls right off. It's amazing.

So thanks for enabling... I have been using the Costco lens cleaner/cloths multiple times daily and now have an ultra sonic cleaner on the way. I was thinking about getting a jewelry cleaner anyway so now this gets those two birds with one stone. now need to work on getting new glasses...

I bougt this small bottle of spray lens cleaner at Walmart's eye center.  My glasses came with a cleaning cloth.  I was told to never use the cloth just dry because it might stratch so I spray with the lens cleaner and then use the cloth to wipe the glasses.

The bottle of lens cleaner was $1.97 and it includes unlimited free refills.

Water and Bounty per Optometrist. I have the Cryzal(sp) coating. This way nothing special is needed and have Bounty towels everywhere and have little spray bottles of water in my car and office.

I use spray lens cleaner and cloths made from old 100% cotton tee shirts, as recommended by optician.

For those who use ultrasonic cleaner do you fill it with glass cleaner or just water? TIA

I use the foil wrapped moistened wipes. I have tried the spray with the cloths, but I got tired of having to carry spray and the cloth in my purse all the time, so now I just keep the foil packets in a couple of places and they work the best at cleaning my lenses, IMO.
