General information

Dried or affixed surgical residues can make cleaning more difficult or ineffective and lead to corrosion. Therefore the time interval between application and processing should not exceed 6 h; also, neither fixating pre-cleaning temperatures >45 °C nor fixating disinfecting agents (active ingredient: aldehydes/alcohols) should be used. Excessive dosages of neutralizing agents or basic cleaners may result in a chemical attack and/or fading and the laser marking on stainless steel becoming unreadable either visually or by machine. Residues containing chlorine or chlorides, e.g., in surgical residues, medicines, saline solutions, and in the service water used for cleaning, disinfection, and sterilization, will cause corrosion damage (pitting, stress corrosion) and result in the destruction of stainless steel products. These must be removed by rinsing thoroughly with demineralized water and then drying. Perform additional drying, if necessary. Only process chemicals that have been tested and approved (e.g. VAH or FDA approval or CE mark) and which are compatible with the product’s materials according to the chemical manufacturers’ recommendations may be used for processing the product. All the chemical manufacturer's application specifications must be strictly observed. Failure to do so can result in the following problems: ■ Optical changes in materials, e.g., fading or discoloration of titanium or aluminum. For aluminum, the application/process solution only needs to be of pH >8 to cause visible surface changes. ■ Material damage such as corrosion, cracks, fracturing, premature aging, or swelling. ■ Do not use process chemicals that cause stress cracking of plastics such as PPSU, or attack silicone softeners and cause brittleness of the material. ► Do not use metal cleaning brushes or other abrasives that would damage the product surface and could cause corrosion ► For further detailed information on hygienically safe and material-preserving/value-preserving reprocessing, see www.a-k-i.org, link to Publications, Red Brochure – Proper maintenance of instruments.

Preparations at the place of use

► Remove any visible surgical residues as much as possible with a damp, lint-free cloth. ► Place the dry product in a sealed waste container and forward it on for cleaning and disinfection within 6 hours.

Preparation before cleaning

► Reprocess the product immediately after use. ► Use suitable cleaning/disinfecting agents if the product is put away in a wet condition. ► Put on the cap (dampness protection) for the camera plug securely before reprocessing.
