Why Automated Cleaning?Why Automated Cleaning?

• Directives state that it is necessary tothoroughly clean an instrument before

sterilization

• Manual cleaning methods have been proven notto be effective when cleaning complex

instrumentation

• Specialised equipment, such as the MedisafeSonic Irrigator, are ultimately more efficient than

a human

• Specialised equipment can provide a validated,repeatable, traceable process

• Cost effective to purchase and to run
