Cleaning and Decontamination
1. To properly care for stainless steel, use cleaners and disinfectants free of
caustic agents such as chlorine, iodine and ammonia.
2. Always follow the application of any cleaner or disinfectant with a
minimum of two clean distilled water rinses, then a thorough drying
with a clean soft cloth. By rinsing with distilled water and drying, any
remaining residue is removed from contact with the stainless steel.
Caution
Never use abrasive cleaners, scouring pads or steel wool when
caring for stainless steel.
s
If the stainless steel does become stained, corroded or rusted, the iron
deposits left on the surface can be removed by neutralizing them with
the passivation process. This process uses an acid to neutralize the
“free iron” deposits left on the steel where there has been deprivation
of oxygen. This stops the spread of the corrosion or rust. It will not
return the stainless steel to its original finish.
All the coated surfaces of this equipment are powder coated. Powder
coating is a method of applying a dry powder to electro-statically charged
metal, then baking in an oven where the dry powder molecules are melted
and fused together. This is by far the most durable finish available today
and, if cared for properly, will last for many years. The coated surfaces
should be cleaned with a neutral detergent and rinsed twice with clean
distilled water, then dried thoroughly with a clean soft cloth. Cleaning or
disinfecting coated surfaces without rinsing with clean distilled water and
drying thoroughly will result in smearing, streaking and dulling of the
coated surfaces. Never use abrasive cleaners, scouring pads or steel wool.
If the coated surfaces do become dull, streaked, smeared or marred in some
other way, there is no known method to restore the finish.
1. Remove all samples from the chamber and store them properly.
2. Remove accessories from the cabinet and disinfect them using the
disinfection procedure recommended by the accessory manufacturer.
3. The work tray(s) and stainless steel components can be removed from
the chamber and disinfected separately.
4. Clean all chamber surfaces with disinfectant.
5. Do not remove the optional UV lights from the sockets. Wipe them
thoroughly with a damp cloth. Do not saturate. Be sure to dry
completely.
