I have had this multi-purpose cleaner a few days and already cleaned 3 very dirty rings,
3 pair of eyeglasses and a necklace and the outcome was great.  It made the glasses as
clear & clean as when they were brand new.  The jewelry, which ranges from 8 yrs to 38 years
old, turned out sparkling clean.  I was very skeptical about how well this will work, but was
pleasantly surprised.  It does a good job.
