Understanding the Importance of Point-of-Use Cleaning

Before delving into the steps, it’s pivotal to recognize the significance of immediate instrument cleaning. This process not only makes subsequent sterilization more effective but also ensures patient safety by reducing the risk of infections. Moreover, it extends the life of surgical instruments and complies with healthcare regulations.

Steps for Effective Point-of-Use Instrument Cleaning


  • Wear appropriate personal protective equipment (PPE): Before handling any used surgical instruments, ensure you wear gloves, protective eyewear, and a gown. This reduces the risk of exposure to bloodborne pathogens and other contaminants.
  • Gather necessary cleaning materials: Depending on the facility’s protocol, this could include soft brushes, enzymatic detergents, or disposable wipes.

Immediate Rinse

  • Rinse instruments with cool water: As soon as an instrument has been used, rinse it under cool, running water. This helps remove blood, bodily fluids, and tissue debris. Avoid using hot water, as it can cause proteinaceous substances to coagulate, making them harder to remove.

Manual Cleaning

  • Apply enzymatic detergent: Enzymatic detergents help break down organic matter, making it easier to remove from the instrument’s surface.
  • Use soft brushes or wipes: Gently scrub the instrument, paying special attention to hinges, joints, and other hard-to-reach areas. Always scrub in the direction of the grain to prevent scratching.
  • Rinse thoroughly: After scrubbing, rinse the instrument under running water to remove all detergent residues.


  • Check for visible debris: Ensure that all surfaces of the instrument are visibly clean. Use a magnifying glass if necessary.
  • Test functionality: Ensure that the instrument’s moving parts operate smoothly. For example, scissors should open and close effortlessly, and forceps should grasp effectively.

Pre-Soaking (if needed)

  • Soak in enzymatic solution: If an instrument is not going to be cleaned immediately in the SPD, it should be soaked in an enzymatic solution to prevent drying of organic material. This is particularly crucial for instruments with lumens or complex designs.

Transportation to Sterile Processing Department (SPD)

  • Use leak-proof, puncture-resistant containers: When transporting instruments to the SPD, they should be placed in appropriate containers to prevent cross-contamination and ensure staff safety.
  • Label as ‘contaminated’: Clearly mark the container to notify SPD staff that the contents have been used and require sterilization.

Best Practices and Tips

  • Stay updated with training: Regular training sessions can help surgical teams stay updated on the best practices for point-of-use cleaning.
  • Avoid using abrasive materials: These can damage the surface of instruments, compromising their functionality and lifespan.
  • Stay informed on manufacturer guidelines: Always refer to the manufacturer’s guidelines for cleaning and maintenance, as different instruments may have specific requirements.


The meticulous process of point-of-use instrument cleaning might appear cumbersome, but its significance in the overarching framework of surgical procedures cannot be overstated. By adhering to the steps and best practices outlined in this guide, surgical teams can ensure the longevity of their instruments, uphold regulatory standards, and most importantly, guarantee the safety and well-being of their patients. The emphasis on immediate cleaning stands as a testament to the medical community’s commitment to excellence in every facet of patient care.
