UltraSpa Manual 19
Never place items to be cleaned directly on the bottom of the ultrasonic
tank. To do so will void the warranty. Rather, to prevent damage to the
tank, its transducer or the item being cleaned, always suspend items
in the ultrasonic tank or use the provided baskets or tweezers that are
made for the purpose.
Always inspect the setting for loose stones prior to cleaning. Stones
that are insecurely set may fall out when cleaned in an ultrasonic or
by a steam cleaner. Prior to cleaning, carefully touch the stone with a
small probe (like a toothpick); the stone should not shift or wiggle.
If
a stone falls out as a result of being cleaned in an ultrasonic
or by a steam cleaner, please be aware that the stone would
have eventually fallen out anyway. Most consider it better to
have a stone fall out in a reasonably controlled environment as
opposed to at random while wearing it.
The following types of jewelry should only be cleaned by a
knowledgeable professional:
· Antique jewelry
· Enamel jewelry
· Paste jewelry (which is common with costume jewelry)
· Costume jewelry
· Jewelry containing stones that have been set with glue
