3 D disinfection process
Is conventional cleaning required before 3 D disinfection?
Yes. 3 D disinfection (cold misting) complements manual cleaning. To achieve optimal effect, surfaces must be visually clean. In addition, 3 D disinfection provides preventive protection against resistant microorganisms.
Can the room be entered during the disinfection process?
During the trial, the room may only be entered wearing a full protective suit. A waiting period must be observed after the process is completed.
How long does it take to disinfect a room?
Disinfection time depends on the volume of space. Please refer to the CleanCube's user manual or the separate application guide.
Where can the CleanCube be used?
CleanCube systems are for use in enclosed spaces designed, among others in:
-
food processing companies
-
Laboratories and cleanrooms
-
Operating rooms and patient rooms
-
Hotels, offices and public transport
-
High-risk environments such as pharmaceutical facilities or virological research facilities
Is training required for operation?
The user manual is self-explanatory. The Steinemann Disinfection Team is always available for further information and application support.
Effectiveness of CleanLine
Why does CleanLine have a disinfectant effect?
CleanLine is made of 7.5% hydrogen peroxide and 0.0075% silver. Upon contact with organic material, hydrogen peroxide decomposes into elemental oxygen, which destroys the cell walls of microorganisms.
Why is CleanLine enriched with silver?
Silver has a strong antimicrobial effect (oligodynamic effect). In combination with hydrogen peroxide, a synergistic, particularly effective biocide effect is created. A higher concentration of silver would not provide additional effectiveness.
How does silver work as a biocide?
Silver:
-
inhibits the proliferation of microorganisms by binding to DNA/RNA
-
blocks enzyme activities by binding to sulfur bridges
-
increases the permeability of the cell membrane and weakens microorganisms
Is CleanLine effective against SARS-CoV-2?
Yes. Coronaviruses are among the enveloped viruses that are particularly sensitive to disinfectants containing hydrogen peroxide.
Proof & Validation
How can it be verified whether disinfection has taken place everywhere?
The distribution of the disinfectant can be checked with test strips placed in hard-to-reach places (e.g. B. be placed under tables or behind furniture).
How is microbiological efficacy demonstrated?
With test slides (e.g. B. TPC) can be performed before and after disinfection to document effectiveness.
What does „AFNOR NFT 72-281 tested mean“?
This is a recognised European test standard for aerosol-based area disinfection. The CleanCube systems fully meet this standard in combination with CleanLine.
Residues & material compatibility
Are furniture, textiles or electronic devices attacked?
Basically no. However, plants and food should be removed. A minimum distance of 3 metres between the device and the object shall be maintained. Due to different materials, no absolute guarantee can be given.
Do residues remain after disinfection?
Hydrogen peroxide breaks down completely into water and oxygen. Silver remains on surfaces in very small amounts and counteracts regermination.
Is silver poisoning possible?
No. Silver poisoning is ruled out. The quantities used are far below critical values, and silver cannot be inhaled.
How much silver is left on the surface?
When used correctly, approximately 2.3 mg of silver per m² remains (at a room height of 2.5 m). This amount is safe and has antimicrobial effects.
