Cleaning ProceduresCleaning Procedures
1.1 Standard Precautions1.1 Standard Precautions
Standard precautions are applied as a first-line approach to infection control. These form the basis for your decision-making and practice. Standard precautions are a set of guidelines based on the assumption that all blood and body fluids are potentially infectious.
1.1 Standard Precautions1.1 Standard PrecautionsIn the context of sterilising practice and ALL the Standard Operating Procedures, standard precautions include:
Hand HygieneHand cream – approved by infection control – not in packing areaPersonal Protective Equipment
• Gloves • Face shields, hair protection, safety glasses and masks• Fluid resistant gowns/aprons
OHS Requirements
1.2 Soiled Pickup Collection1.2 Soiled Pickup Collection Standard Precautions - PPE Contaminated items - dedicated collection trolley/cart Keep instrument sets together Follow the designated route with trolley (OHS)
Collection containers are: puncture-resistant leak-proof and made of either plastic or metal with a lid or liner that can be closed
1.2 Soiled Pickup Collection1.2 Soiled Pickup Collection Cleaned items must be dried prior to transport Reusable instruments cassettes and single items placed into
designated transport containers Secure single loose items Don’ts Place heavy instruments on light instruments Lift above shoulder height Containers should not exceed 10 kgs
Containers for Transport from SurgeryContainers for Transport from Surgery with a lid easily cleaned puncture and leak proof kept in a clean, dry condition not overloaded carefully packed
sharps recognised facing same direction
1.3 Sorting Prior To Cleaning1.3 Sorting Prior To CleaningInstruments and items sorted by;
• Type • Method of cleaning e.g. Manual , ultrasonic,
Instruments and items are checked for;• Completeness• Defects• Sharps or blades that have not been removed• Heavily soiled items• Single use only items are not to be returned for
reprocessingReport concerns to supervisor
CleaningCleaning Cleaning removes organic and inorganic soil, blood,
fats etc which contain pathogenic micro-organisms
Cleaning minimises contamination levels of bioburden (number of micro-organisms) prior to sterilisation
For sterilisation to occur the aim is to have a low number of micro-organisms present on instruments
CleaningCleaning
Steam will not penetrate contamination left on instruments
If the item is not clean it won’t be sterilised
1.4 Chemical & Detergent Mixtures1.4 Chemical & Detergent Mixtures
Breaking down and removal of Blood, proteins and debris (organic soils) Medicaments and chemicals (inorganic soils) Breaks water tension – surfactant Keeps the soils suspended in the water

detergents
1.4 Chemical & Detergent Mixtures1.4 Chemical & Detergent Mixtures
Drying Agents/Rinse Aids – Washer disinfectors Surfactants that “wet” the final rinse water Automatically dosed into the final rinse water Spreads evenly over a surface instead of beading Beaded water leaves mineral salts Not as effective on plastics Load instruments and metals on the top racks with plastics on
the bottom Plastics on edge to allow drainage
1.4 Chemical & Detergent Mixtures1.4 Chemical & Detergent Mixtures
Acid Base Agents Only on stainless steel surfaces Only intermittently descaling or destaining Dissimilar instruments should not processed at the same time Mix the agent as per manufacturers instructions Only mix when required and discard at end of the day OHS -Chemical manufactures instructions , including safety
precautions, dilution and instrument compatibility OHS - Rubber or nitrile gloves
1.4 Chemical & Detergent Mixtures1.4 Chemical & Detergent Mixtures
Lubricants Water miscible – able to mix with water Compatible with the sterilizing agent As per manufacturers instructions Instrument stiffness needs to be investigated Lubrication used intermittently Routine use = heavy contamination
1.5 Pre Cleaning1.5 Pre Cleaning Pre cleaning (initial cleaning) allows for the removal
of visible blood, body fluids and debris from items prior to cleaning (definitive cleaning). Pre cleaning shall be undertaken as soon as possible (e.g. during and post procedure chairside).
If blood, proteins and other debris are allowed to dry or remain in crevices and joints, the instruments become very difficult to clean and are prone to stiffness and accelerated corrosion.
1.5 Pre Cleaning1.5 Pre Cleaning
Pre cleaning can be performed by methods such as dry wiping, damp wiping or use of a commercially available single use only instrument sponge
Place the dry wipe, damp wipe or sponge on the bracket table and carefully wipe the instrument across the material
1.5 Pre Cleaning1.5 Pre Cleaning
Rinsing removes excess blood and debris Prevents blood and debris drying on items As soon as possible - post procedure Reduces bioburden - micro-organisms will multiply rapidly Use warm water
hot water coagulates protein cold water - congeals fats

Initial rinse - Some items may be gently rinsed with warm water to remove gross soil as per manufacturer’s instructions.
Initial rinse - Some items may be rinsed using a low lint cloth immersed in water if the item cannot be placed under gently running water
Fill sink correct ratio of warm water and suitable detergent Items are wiped using a clean cloth immersed in the clean,
warm water with detergent added The cloth is squeezed (wrung out) to prevent water entering
the instrument, it is damp only, and not dripping wet
1.7 Hand Cleaning For Non-immersible Items1.7 Hand Cleaning For Non-immersible Items
The impregnated damp cloth is rubbed over the item
May need to be repeated depending extent of soiling
Handpieces that cannot be immersed in water follow the
manufacturer’s instructions
Non-immersible cannulated items - the manufacturer’s
instructions must be adhered to in relation to flushing and
brushing
1.7 Hand Cleaning For Non-immersible Items1.7 Hand Cleaning For Non-immersible Items
Following washing the detergent must be removed
FINAL RINSE - Using a damp clean low lint cloth (that has not
been in contact with detergent), wipe over the item to
remove the detergent. Note if a demineralised/reverse
osmosis water system is installed, rinse with demineralised/
reverse osmosis filtered water
These steps may need to be repeated to remove all traces of
detergent (Dry as per instructions in SOP 1.6 immersible item)

1.8 Ultrasonic Cleaner1.8 Ultrasonic Cleaner
Purpose
Ultrasonic cleaning is a form of mechanical cleaning
that uses high frequency ultrasonic waves (cavitation)
that dislodges fine particles from the surfaces of
instruments.
Ultrasonic cleaning is an effective cleaning method for instruments prior to the reprocessing
1.8 Ultrasonic Cleaner1.8 Ultrasonic Cleaner Minimises manual cleaning Does not disinfect instruments Remove debris using cavitation (sound waves) Detergent as per manufacturer’s instructions Requires degassing before use Rinsing after use (if no further washer/disinfector processing) OHS – do not immerse hands when operating OHS – aerosols – use lid when operating OHS – noise – use lid & hearing protection OHS – dry hands – when handling electrical leads and turning
on or off at power point.
