1.4. CLEANING AND DISINFECTION
Cleaning is the first step of any disinfecting process.
Physically scrubbing with detergents and surface-active substances and rinsing with water removes a considerable amount of micro-organisms. If a
surface is not clean first, the disinfecting process cannot be successful.
If a surface cannot be adequately cleaned, it should be protected with barriers.
The outer parts of the equipment must be cleaned and disinfected using a product for hospital use with indications for HIV, HBV and tubercolocide
(medium-level disinfectant) specifically for small surfaces.
The various drugs and chemical products used in dental surgeries may damage the painted surfaces and the plastic parts. Researches and tests
performed show that the surfaces cannot be fully protected against the harsh action of all products available on the market. We therefore recommend
protecting with barriers whenever possible.
The harsh actions of chemical products also depend on the amount of time they are left on the surfaces.
It is therefore important not to leave the product on the surfaces longer than the time specified by the manufacturer.
It is recommended to use the specific medium-level disinfectant, STER 1 PLUS (CEFLA s.c.), which is compatible with:
• Coated surfaces and plastic parts.
• Upholstery.
The MEMORY FOAM upholstery will stain when splashed with mordant acid. Immediately rinse with plenty of water if acid splatters
on the upholstery.
• Uncoated metal surfaces.
If you do not use STER 1 PLUS, it is recommended to use products that contain at maximum:
• Ethanol. Concentration: maximum 30 g per 100 g of disinfectant.
• 1-Propanol (n-propanol, propyl alcohol, n-propyl alcohol). Concentration: maximum 20 g per 100 g of disinfectant.
• Combination of ethanol and propanol. Concentration: the combination of the two should be maximum 40 g per 100 g of disinfectant.
• Do not use products containing isopropyl alcohol (2-propanol, iso-propanol).
• Do not use products that contain sodium hypochlorite (bleach).
• Do not use cleaners that contain phenols.
• Do not spray the selected products directly on the surfaces.
• All products must be used as directed by the manufacturer.
• Do not mix the STER 1 PLUS disinfectant with other products.
The products suggested are compatible with the materials of the equipment, however damages may occur to surfaces and
materials resulting from the use of different products, even if not included in the above list of excluded products.
Cleaning and disinfecting instructions.
Clean and disinfect with disposable non-abrasive paper (avoid using recycled paper) or sterile gauze.
Do not use sponges or, in any case, any material that can be reused.
• Turn off the dental unit prior to cleaning and disinfecting the external parts.
• All materials used to clean and disinfect must be thrown away.
