Cleaning and Disinfecting Stainless Steel
Simple Cleaning
IMPORTANT
Do not use steel wool or steel pads when cleaning stainless steel.
Dirt deposits on stainless steel (dust, dirt and finger marks) can easily be removed. Usually, warm water,
with or without detergent, is sufficient. If this does not remove the deposits, mild, non-abrasive household
cleaners can be used with warm water and bristle brushes, sponges or clean cloths.
Iron rust discoloration can be treated by rubbing the surface with a solution of 15% to 20% by volume of
Nitric Acid and water and letting it stand for one to two minutes to loosen the rust.
Disinfection
The purpose of disinfection is to destroy particular organisms that could pose a potential hazard to humans
or compromise the integrity of the experiment. It is important to use a suitable disinfectant in the
concentration appropriate to the organism being killed. Standard disinfectants include: Hypochloride
(chlorine bleach), Iodophor-Detergent, Ethanol, Phenol and Alcohol.
IMPORTANT
Disinfection and cleaning should always be followed by rinsing in sterile hot water and wiping the
surface completely dry.
Disinfect the work surface before and after every procedure.
1.
Disinfect surfaces of all equipment used.
2.
Remove all items from the inside of the cabinet.
3.
Place all items that may have come in contact with the agent(s), such as used pipettes, in a plastic
bag or other suitable container.
4.
Disinfect the entire inside surface of the cabinet.
