Stainless Steel Care and Cleaning

To prevent discoloration of rust on stainless steel several important steps need to be

taken. Stainless steel contains 70-80% iron which will rust. It also contains 12-30%

chromium which forms an invisible passive film over the surface which acts as a shield

against corrosion. As long as the protective layer is intact, the metal is still stainless. If

the film is broken or contaminated, outside elements can begin to break down the

steel and begin to form rust of discoloration.Proper cleaning of stainless steel requires

soft cloths or plastic scouring pads,

Cleaning solutions need to be alkaline based or non-chloride cleaners. Any cleaner

containing chlorides will damage the protective film of the stainless steel. Chlorides

are also commonly found in hard water, salts, and household and industrial cleaners.

If cleaners containing chlorides are used be sure to rinse repeatedly and dry thor-

oughly upon completion.

Routine cleaning of stainless steel can be done with soap and water. Extreme stains

or grease should be cleaned with a non-abrasive cleaner and plastic scrub pad. It is

denser coil.If heavy grease is present there are de-greasing agents available for re-

frigeration use and specifically for the condenser coils. The condenser coil may re-

quire a spray with the de-greasing agent and then blown through with compressed

air.Failure to maintain a clean condenser coil can initially cause high temperatures

and excessive run times, continuous operation with dirty or clogged condenser coils

can result in compressor failures. Neglecting the condenser coil cleaning procedures

will void any warranties associated with the compressor or cost to replace the com-

pressor.

In order to maintain proper refrigeration performance, the condenser fins must be

cleaned of dust, dirt and grease regularly. It is recommended that this be done at

least every three months. If conditions are such that the condenser is totally blocked

in three months, the frequency of cleaning should be increased. Clean the con-

denser with a vacuum cleaner or stiff brush. If extremely dirty, a commercially avail-

able condenser cleaner may be required.
