Ultrasonic Spectacle Cleaner 2 "Ultrasonic Glasses Cleaner" Christine 19 October 2010 Having owned an ultrasonic Jewellery Cleaner for many years, I thought that the ultrasonic spectacle cleaner was just what I needed to clean my glasses which I wear non-stop from when I get up in the morning until when I go to bed at night. As I live in Italy where it is hot and humid for many months of the year, not only do the lenses get really dirty, but the frames as well, especially the bridge across the nose and the nose pieces. I am afraid to say, however, that I am disappointed in the performance of this item. Using only warm water as suggested in the instruction leaflet certainly did NOT get the lenses clean. The result was better when I added some washing up liquid but, even so, I had to give the glasses a good polish with a drying up cloth before the glass was clear. I might as well use the little cloth and spray supplied by my optician! This Spectacle Cleaner just doesn't compare with my ultrasonic Jewellery Cleaner but admittedly the latter uses special liquid for cleaning and cost five times as much! A note from the team Thanks for your review. I'm sorry you'd be disappointed with the performance of the spectacle cleaner. I'll be in touch shortly.
