Around 20 minutes should be enough to remove/loosen most foreign bodies from the item you
are cleaning. There is no specific recommended duration for a cleaning cycle but generally the
shorter the better to minimize the possibility of damage to the item being cleaned especially if it
is to be cleaned regularly. It will reduce the ultrasonic cleaning cycle time by soaking the item to
be cleaned for as long as possible before ultrasonic cleaning. It is recommended after cleaning is
completed to perform a short rinse cycle with clean water to ensure cleaning agent deposits are
not left in obscured areas of the object.
The action of ultrasonic cleaning will slowly micro pit the surface of metals, aluminium is
particularly easily eroded. The softer the metal the more rapidly it will be eroded which may be a
concern with polished machined and aesthetic parts which need to be cleaned regularly.
Gemstones including those used in jewellery and clocks should be cleaned with great caution.
Some stones are surface eroded, can lose colour or become discoloured, crack due to ultrasonic
shock and/or heat, see the list below for stones which are unsuitable for ultrasonic cleaning,
Please note; this list is for reference only and is by no means exhaustive;
Pearl, Opal, Amber, Tanzanite, Emerald, Peridot, Agate, Amazonite, Topaz,
Aquamarine, Turquoise.
Please note; this information is for reference only and is not exhaustive
Weaker gemstone settings such as Grain, Pave and invisible can be loosened by ultrasonic
cleaning. Mechanically superior settings such as Claw and rubover are not generally affected.
Certain electronic components are considered sensitive to ultrasonic cleaning, unfortunately,
there is very little empirical published data regarding this subject. In general, it is safe to clean
the vast majority of electronic components. To minimize the potential for damage, turn the basket
occasionally during the cycle to stop ultrasonic hotspots and use an effective aqueous solvent to
quickly remove the contamination.
You should consider adhesives used in the object being cleaned, these can be attacked/softened
by the detergent/solvent used and the bond undermined by the ultrasonic effect.
Fully immerse item into the water. Ensure there are no air pockets in recesses and blind holes/
chambers to ensure the ultrasonic effect can propagate to all surfaces of the item being cleaned.
