This procedure prevents the risk of infection during cleaning and maintenance.

♦ Dampen the instrument with a non-corrosive disinfectant (pH from 2.5 to 9) or with 70-80% ethyl alcohol.

♦ Comply with the disinfection reaction times recommended by the manufacturer.

DO NOT : Immerse or vaporise the instruments. Do not allow the disinfectant to come into contact with the instrument, poor rinsing, etc. Do not use cloths containing chlorhexidine or aldehydes.

If any traces of disinfectant are left on the instruments, the latter will become corrosive when heated. This may cause extensive damage during sterilization: oxidation, modification to the technical characteristics of seals, rubber, fibre optics, etc.

This procedure involves the removal of residues (blood, dentine, etc.) which adhere to critical areas such as spray outlets, fibre optics, etc.
