  1. Water Spots on Medical Devices After Washer Cleaning

    Water Spots on Medical Devices After Washer Cleaning
    Q. We are washing stainless medical devices in a washer and are getting water spots. We are using Solujet and Citrajet. What’s causing this problem? A. Water spots typically occur because of two main reasons: the orientation of the parts in the washer is trapping dirty wash water and/or detergent dosing is insufficient. If any items being washed have a shape that can retain dirty wash water, it can sometimes get carried into the next rinse cycle and spread all over all the items being washed. An example of a such a shape would be “U” shapes or cups. Then the parts gets dried and the residue from the dirty wash water leaves water spots. To solve this, load the items in a way to tilt them so they drain completely and do not carry dirty wash water from the wash cycle to the rinse cycle. If this is not an issue, then consider detergent dosing. If you are washing with hard tap water (high in calcium, magnesium and iron), and you are under-dosing the detergent, then there may not be enough chelating agent to tie up the hardness ions. In this case, these ions will precipitate out as metal oxides/hyrdroxides/carbonates that then do not rinse easily and can lead to water spots. Be sure to use at least a 1% Solujet® Low Foaming Phosphate Free Detergent wash solution (10 mL/L) and 1% Citrajet® Low Foaming Acid Cleaner rinse solution (10 mL/L). Also consider using deionized, RO, or distilled water for rinsing, and even washing, which can help completely avoid this problem. Note that high quality water is less important for the wash step.

    Cleaning Denatured Proteins

    Q. We are looking to clean denatured proteins from our medical device along with baked-on desiccated blood that is not removed completely. Manual scraping removes the residual but is not acceptable. Need a cleaner that will dissolve all bio-matter. Cleaning process is to prepare device for autoclave sterilization.

    Ensure Ultimate Protection For Staff Health & Safety When it comes to chemical hazards, are you protecting what matters most in your facility?

    New globally harmonized chemical labeling rules have been enacted to protect workers who come into contact with hazardous chemicals. Primary chemical containers are now labeled with new Globally Harmonized System (GHS) icons and cautions. To avoid confusion and protect employees, shouldn’t your secondary containers have the same label information?

    Using Thermo Scientific™ Nalgene™ Right-to-Understand wash bottles labeled with current GHS information provides many benefits:

    • A safer work environment
    • Increased efficiency
    • Fewer accidents and illnesses
    • Greater awareness of hazards, resulting in safer use of chemicals in the
    • workplace and at home
