      Why is my Prevention™ HLD8 solution turning cloudy or discolored before the 21-day reuse period?

      There are a few different reasons why your Prevention™ HLD8 solution may be turning cloudy or discolored before the 21-day reuse period, for example, improper storage, contamination from dirt or other liquids, or incompatible tools or containers. Here are a few important things to remember:


      • During the 21-day reuse period, there are test strips that should be used in the solution between each use to ensure that the solution is still maintaining the same disinfecting efficacy on day 2, 5, 10, etc. The solution should be replaced immediately if the test strips do not read the solution as being accurate, or if the solution is visibly contaminated with any dirt or soil particles.
      • The solution should be stored in a sealed container, out of direct sunlight, and away from any extreme temperatures.
      • Your tools should always be pre-cleaned using water and a detergent, rinsed with clean water and dried, before being placed in the soaking tray with the Prevention™ HLD8 solution.
      • It is important not to leave your tools soaking in the Prevention™ HLD8 solution for longer than 8 minutes. As soon as the 8-minute soaking time has been achieved, you should remove the tools and rinse them with water, then dry them and store them in a sealed container until their next use.

      If you are following these directions for storage and use appropriately and you are still noticing cloudy or discolored solution, this can be an indicator that there is a compatibility issue with your tools. Prevention™ HLD8 solution has been tested and found to be compatible with the materials listed below:





      Mild steel, Gold plated steel, Chrome plated steel, 302 stainless steel, 304 stainless steel, 316 stainless steel, 410 stainless steel

      High-density polyethylene (HDPE), PTFE (Teflon®), Polyester, Polystyrene, Polycarbonate (Lexan®), Polypropylene, Acrylic, Polyvinyl Chloride (PVC), Acrylonitrile Butadiene Styrene (ABS), Nylon

      Neoprene, EPDM 42, Silicone Rubber, Viton-A, Polyurethane, Natural Rubber (Red)


      It is a good idea to check with your tool manufacturer for their suggestions or recommendations for cleaning and disinfection, as they may have experience with certain solutions or practices that they do or do not recommend for their tools.
