The cleaning process aims at removing dirt from instruments. After the collection and decontamination phases, the washing process begins: it can be manual or mechanical using ultrasonic tanks or the thermodisinfector. The thermal disinfection process cleans instruments with heat and avoids washing and drying them manually.
The thermal disinfecion process works thanks to the combined action of detergents, temperature and time. It kills fungi, bacteria and viruses, including HBV and HIV.
This phase is carried out using ultrasonic tanks. They plays a crucial role by cleaning parts of instruments that cannot be reached otherwise and by removing dirt such as cements and plaster.
