
Part Exposure - In order for a surface to be cleaned, it must be exposed to the liquid.
This requires proper placement of the parts in the parts basket. Do not overload
baskets with small parts that prevent the middle layers from getting proper exposure
to the liquid. Also, improper placement of parts with blind holes or cavities can result
in air pockets, where no cleaning action occurs. In general, clean large numbers of
parts a few at a time using shorter cleaning cycles.

Contaminated Solution - As contaminants build up in the solution the ultrasonic
performance drops. The cavitation bubbles waste their energy imploding on the
contaminants and not on the part surface. It is important that you change the solution
on a regular basis.

Parts Materials and Contamination - Certain materials absorb ultrasonic energy,
generally these are soft materials like rubber, fabric, gaskets and heavy grease.
Ultrasonics is extremely effective with a hard surface to impact against. Therefore,
parts contaminated with heavy amounts of grease or soft materials should be pre-
cleaned prior to exposure to the ultrasonic tank.
