What is the advantage of freshly mixed solution when using enzymatic products for pre-cleaning and manual cleaning of endoscopes?

Enzymes are a premium ingredient to help dissolve soils, especially in areas where brushing and scrubbing is difficult. Over time a pre-diluted enzyme solution will weaken as enzymes attack each other during storage leaving you with less cleaning action. QEZ Bedside Kits use pre-saturated sponges dosed with concentrated ProEZ AW Quad detergent. Squeezing the QEZ sponge in water releases the enzymes for fresh cleaning action.
