1.7.5. CLEANING AND DISINFECTION
Cleaning is the first step necessary in any disinfection process. The physical action of rubbing a surface with
detergents and surface-active agents and rinsing with water removes a large number of microorganisms. If a
surface is not cleaned first, the disinfection process cannot be successful.
When a surface cannot be adequately cleaned, it should be protected with barriers.
The external parts of the device must be cleaned and disinfected using a product for hospital use with indications for
HIV, HBV and tuberculosis (medium-level disinfectant) specifically for small surfaces.
The various drugs and chemical products used in dentist’s surgeries may damage the painted surfaces and the plastic
parts. The tests and research conducted have demonstrated that the surfaces cannot be fully protected against attack
of all the products found on the market. It is therefore recommended to use barrier protections whenever possible.
The aggressive effects of chemical products also depend on the time they stay in contact with the surfaces. It is
therefore important not to leave the product on the surfaces of the device for longer than the time indicated by the
manufacturer.
It is recommended to use the specific medium-level disinfectant, STER 1 PLUS (CEFLA S.C.), which is compatible
with the painted surfaces, plastic parts and unpainted metal surfaces. Alternatively, it is recommended to use products
that contain:
- 96% ethanol Concentration: maximum 30 g for every 100 g of disinfectant.
- 1-propanol (N-propanol, propyl alcohol, N-propyl alcohol). Concentration: maximum 20 g for every 100 g of
disinfectant.
- Combination of ethanol and propanol. Concentration: the combination of the two must be at maximum 40 g for
every 100 g of disinfectant.
- Painted surfaces and plastic parts.
- Incidin Spezial (Henkel Ecolab);
- Omnizid (Omnident);
- Plastisept (Alpro) (not tuberculocide as not an alcohol-based disinfectant);
- RelyOn Virkosept (DuPont);
- Green & Clean SK (Metasys) (not tuberculocide as not an alcohol-based disinfectant).
- Do not use products containing isopropyl alcohol (2-propanol, isopropanol).
- Do not use products containing sodium hypochlorite (bleach).
- Do not use products containing phenols.
- Whatever product you use, follow the instructions given by the manufacturer.
- Do not mix the STER 1 PLUS disinfectant with other products.
- Do not spray the product directly on the device surfaces.
For cleaning and disinfection use disposable, soft, non-abrasive
paper (do not use recycled paper) or sterile gauze.
- It is recommended to turn off the device before cleaning and
disinfecting the external parts.
- Everything used for cleaning and disinfection must be thrown
away after use.
