• Various solutions may inhibit the functioning of a unit (powder or tablet). It may therefore be
necessary to dissolve the powder/liquid solutions in warm water prior to being added to the
tank or use warm water in the tank and then perform the performance test.
2. "How long should I clean my instruments?"
Listed below are several points to consider when determining the duration of any cleaning cycle.
Adjustments to one or more of these points may be needed to achieve the desired level of
cleaning.
NOTE: Always consult the manufacturer or suppliers instructions for use before cleaning a device.
The below guidance cannot be used to replace the cleaning instructions provided by the
manufacturer of the instruments; they are provided to help users get the most out of each
cleaning cycle. If soil is still visible after the completion of a cleaning cycle, modification to one or
more points may be required, and then additional cleaning cycles may be required until all soil is,
at a minimum, visibly removed. It is the responsibility of the user to verify that a cleaning cycle
was effective. The user must inspect all devices for a satisfactory level of cleaning before
continuing to the next step in the infection control process.
• Size of the load being cleaned
The more instruments placed into an ultrasonic bath, the less effective the cleaning
cycle will be. It is not recommended to place instruments in the basket so that they
overlap, as open surface areas will be easier to clean. Filling a basket with clear space
between instruments should lead to a more effective cleaning cycle.
• Amount and type of soil to be removed
Some contaminates have a stronger bond to the instruments being cleaned and may
need a longer cleaning cycle. Also, the amount of soil on the instruments being cleaned
has an effect on the time required to complete a cleaning cycle.
• Type of cleaning solution used
Not all kinds of cleaning solutions are the same in regards to cleaning effectiveness.
Some cleaning solutions work well on some contaminates, but not as well on other
contaminates.
• Type of water
Not all water is the same and may vary in level of contaminates and hardness which can
affect the level of cavitation in the solution. This can increase or decrease the time of a
cleaning cycle.
