Principles of Surgical Instrument Cleaning
Immediate Post-Use Care
• Following surgery, immediately rinse or wipe instruments to prevent blood and tissue from drying on surfaces.
• Carefully handle sharps and delicate items to avoid injury or damage.
Pre-soaking
• If cleaning can’t be performed right away, place instruments in a tray of lukewarm water or pH-neutral enzymatic solution to loosen debris.
• Never use hot water, as it can set proteins and make removal harder.
Manual Cleaning
• Dismantle multi-part instruments where possible (e.g., separating removable parts of scissors or needle holders).
• Use a soft nylon brush under running water to clean all surfaces—including joints, box locks, hinges, serrations, and lumens. Pay special attention to grooves and crevices where debris may accumulate.
• Avoid steel wool or abrasive materials that can scratch or damage instrument finishes.
Ultrasonic Cleaning
• Place instruments in an ultrasonic cleaner using manufacturer-approved solutions. This method removes microscopic debris from hard-to-reach areas, especially important for hinged or ratcheted instruments.
• Do not overload baskets; ensure all surfaces are exposed to the cleaning action.
Rinsing and Drying
• Rinse instruments thoroughly with deionised or distilled water to remove all traces of cleaning agents.
• Dry completely with lint-free towels or allow to air-dry. Even minimal moisture can cause corrosion or pitting.
