STAINLESS STEEL INSTRUMENT CLEANING & CARE
Required Cleaning Items:
• Distilled water with a neutral pH of 6-8.
• Enzymatic Cleaning Solution with a neutral pH of 6-8 is highly recommended.
• Detergent with a neutral pH of 6-8.
New Instruments:
Should be disassembled and thoroughly cleaned BEFORE sterilization to remove manufacturing residue or foreign debris.
Distilled Water:
Immediately after use, submerge instrument(s) in distilled water. Keep submerged until the cleaning steps begin.
Enzymatic Soak:
Disassemble instruments and submerge them in an approved enzymatic solution following the manufacturer’s recommen-
dation. All instruments must be in the unlocked, un-ratcheted, jaws-open position to expose as much of the instruments’ surfaces as possible.
This helps to keep blood, debris and protein matter from sticking to the instrument surfaces and crevices.
Rinse to Remove the Enzymatic Solution and Loose Bio-debris:
Rinse the instruments with warm tap water before instrument clean-
ing/scrubbing begins.
Cleaning Instruments:
Instruments should be scrubbed using approved brushes and a detergent with a neutral pH of 6-8. Immerse instru-
ment in the detergent solution and clean with a small nylon bristled brush concentrating on the box-lock, hinged areas, ratchets, serrated jaws
and tip areas. Use caution while cleaning sharp tip instruments and instruments with teeth so not to damage those delicate areas. A soft cloth
or lap sponge can be used to clean the shafts and shanks of the instrument. Stainless steel wire brushes approved for use on surgical instru-
ments can be used for cleaning difficult areas such as serrations, bone rasp and instrument handles with grooved areas.
Rinse:
Immediately after scrubbing, rinsing the instruments in distilled water is preferred. If using tap water be sure to wipe and dry the
instrument with a soft cloth. Open the instruments to expose all surfaces to ensure all the detergent residues are wiped off all possible surfac-
es. Pay particular attention to the box lock, hinged areas, and small crevice areas.
Inspection:
Visually inspect each instrument to ensure cleanliness and performance. Inspection should include check-
ing scissor blade closure, thumb forceps with 1x2 teeth and with serrations, and are properly aligned when closed. Hemostats and needle
holders should open and close smoothly with uniform jaw closure.
Drying by Hand:
Instruments must be thoroughly dried before being wrapped or placing them in a basket for sterilization.
IMPORTANT STEP:
Any cleaning moisture left on the instruments may contain detergents or minerals that will cause spotting, staining, dis-
coloration, corrosion and will lower the performance and life expectancy of the device.
Lubrication:
Lubrication should be applied before each sterilization. Instruments should be soaked or sprayed with water soluble instrument
milk on the hinges and sliding parts of the instruments. This helps the instruments move freely during use. The instrument lubricant also helps
build up a Passivation layer on the instrument surface. This layer acts like a wax coating to help resist blood, debris and or other protein mat-
ter from sticking to the instruments. It also helps resist mineral deposits on the instrument surface. Silicon or Petroleum based lubricants are
not recommended for surgical instruments. Instruments can now be made ready for the sterilizer.
Sterilization:
Sterilize as recommended by the AAMI Standards and Recommended Practices, Volume 1, 1992, and the sterilizer manufactur-
er’s written instructions for cycle parameters including pH balanced distilled water.
Sterilization of instruments may be accomplished by Autoclave or Ethylene Oxide. Time and temperature parameters required for sterilization
vary according to type of sterilizer, cycle design, and packaging material.
• Do not sterilize instruments at temperatures over 141°C (285°F).
• All ring handled instruments must be autoclaved in the fully open position to prevent cracking of the box lock.
• Always verify parameters with sterilizer manufacturer’s written instructions.

Storage:
• After Sterilization, instruments should remain in sterilization wrap and be stored in a clean, dry cabinet or storage case.
• Care must be taken to protect the jaws from damage.
• Lubricant or Instrument Milk.
• Nylon brush or approved stainless steel bristles.
