Rinsing

Immediately after use, rinse instruments under warm running water. This should remove all blood, body fluids and tissue.

Cleaning

If not carried out after immediately after rinsing, instruments should be submerged in a solution of non-corrosive neutral detergent pH (7). a)

Ultrasonic Cleaning

This is the most effective cleaning method, ensure that any hinged or ratchet instruments are in the ‘open’ position and take care that any sharp blades of scissors, curettes, etc. do not touch other instruments. All instruments must be submerged in the cleaning solution.

Do not ‘overcrowd’ instruments in the washer. (This cleaning method may not be suitable for some delicate instruments, alternatively they can be cleaned manually as explained in step b). b)

Manual Cleaning

If ultrasonic washing is not available, instruments can be washed manually prior to sterilisation. Observe the following steps: Use stiff cleaning brushes, such as nylon.

Do not use steel wool or wire metal brushes. Use only neutral detergent solutions with pH 7.

After scrubbing rinse instruments thoroughly under running water.

Drying & Lubrication

Immediately after cleaning and rinsing instruments should be carefully dried. All instruments with hinges, locks and moving parts should be lubricated. This can be a good time to inspect instruments for any defects.

Autoclaving

After the previous operations the instruments are ready for autoclaving. Instruments should be placed evenly spaced. Avoid overcrowding as pockets can form preventing steam penetration.

Ensure any hinged instruments are in the open position. At the end of the autoclave cycle it is recommended that the door be only ‘cracked’ open before the drying cycle. Opening the door fully causes condensation to form on the instruments resulting in water stains on the surface.

Important

• Do not expose instruments to temperatures above 180ºC (355ºF)
• Do not use Bleach or corrosive chemicals
• Do not use dry heat sterilisation for silicone handle instruments
