Some Hemoglobin
Poor chemical activity and some
spray obstruction
This appearance represents poor cleaning efficiency. Both mechanical spray cleaning efficiency and chemical cleaning are inefficient. Check for blocked feed lines in the cleaning solution bulk tanks or malfunction of the feed pump. Check for low water pressure in the spray arms.
Check for temperature out of specification, 110°F - 140°F for enzyme soak and 140°F - 160°F for wash phase. Increase wash and soak times if possible.
On rare occasions it is possible that the proteins on ProFormanceTM could have been denatured and rendered insoluble. This happens if the ProFormanceTM is heated too high in the initial rinse phase. Another possibility is denaturing from alcohols during pre-soaking. Some enzyme detergents have a high concentration of alcohol. When exposed to 100% strength enzyme cleaner that contains alcohol, the albumin in ProFormanceTM (and in blood for that matter) may become denatured and rendered insoluble. Follow manufacturer's directions regarding dilution of enzyme cleaners for pre-soaking.
Make sure the initial rinse phase is with cold or cool tap water.
Check for overloading.
