Pre-Klenz Instrument Presoak & Detergent

The moment surgical instruments leave the sterile field, the clock starts. Blood, tissue, and other bioburden begin to dry onto surfaces and lumens within minutes, and once dried, that soil is far harder to remove — compromising every downstream cleaning and sterilization step. Pre-Klenz from SC Johnson Professional is formulated for exactly this window: applied at the point of use, it keeps soil moist and starts breaking it down before instruments ever reach the decontamination sink.

This collection carries Pre-Klenz in the formats sterile processing and OR staff actually reach for. The Pre-Klenz Instrument Presoak Spray (22 oz., 150377) delivers a floral citrus-scented enzymatic detergent in a convenient spray bottle for treating instruments and trays right after a procedure. The Pre-Klenz Point-of-Use Instrument Presoak gel (13.5 oz. aerosol, 1505J5) is a ready-to-use gel that clings to vertical surfaces, hinges, and box locks, so it stays where you spray it during transport back to decon.

Why a gel versus a liquid spray? The gel formulation resists dripping and runoff, making it well suited to instruments held upright in trays or contaminated devices that sit before reprocessing. The liquid spray covers larger loads quickly and is easy to apply across multiple trays. Many facilities keep both on hand — the spray at the sterile field, the gel for transport containers.

Because both products are enzymatic presoaks rather than a final cleaning step, they're designed to work ahead of your standard manual or automated washing protocol, helping ensure instruments arrive at decontamination ready to clean rather than caked and dried. The floral citrus scent also helps manage odor during handling and transport.
