    3M's domestic "Scotch Brite Pads" seem very good for cleaning provided they are used gently and not on polished stainless steel. The cleaning procedure needs to be qualified as to whether it is being applied to:

    * Physical removal of deposits and their type, e.g. fingerprints,
    atmospheric deposits surface corrosion products, organic material or
    building materials.
    * maintenance of an architectural finish.
    The original surface finish of the stainless steel.

    Cleaning

    Stainless steel is often thought to be a upkeep-free material. not like gold and platinum, however, it is not a metal that never rusts and is not completely maintenance-free. Rather, it should be termed a building material whose beauty can be retained semi-permanently with proper cleaning and upkeep in addition to considerations as cited above, concerning design, fabrication and installation.

    Generally, distinctive stainless steels with excellent corrosion resistance should be used for building entrance applications in seashore places. A proper cleaning and upkeep routing, however, permits the use of frequent grades such as S30400 and S31600.

    The cleaning frequency varies according to the geographical location, building element and strucutre; the general cleaning standards are:

    - 2 times/year for rural regions;
    - 3 times/year for other parts.

    A more frequent cleaning program is advisable for more corrosive environments, however, suchas seashore parts, laden heavily with wind-borne sea salt particles, places near railroad tracks or iron works laden heavily with airborne iron particles, and volcaninc parts. Even in less corrosive environment - eaves, soffits, under-eave components and other building components - on which pollutants readily accumulate, should be cleaned more frequently.

    routine Cleaning and upkeep

    Both exterior and interior building components require routine cleaning, the frequency of which is dependent upon environmental conditions and aesthetic requirements.

    Well-designed facades will be successfully cleaned by rain reducing the sum of supplemental, program- c;eaning to once or 2 times a year (about as often as the windows).

    When severe environmental conditions are encountered (such as high chloride, marine environments or environments that may be compunded by high concentrations of aggressive pollutants) or where design uses the rain less effeciently, more frequent washing may be necessary. and a guide is supplied.

    For heavier soiling, pressure jet cleaning with hot water to remove material, followed by rubbing with a suitable mild-abrasive cleaner, a water rinse and drying should do. If left on the surface chlorine compounds, in many cleaning compounds, may cause corrosion and cleaners with these substances should be avoided.

    distinctive care must be taken with chemically coloured or painted stainless metallic. Providing care is taken not to damage the surface the method detailed as follows, is suitable:

    * Rinse the water to remove loose dirt.
    * Wash with water containing soap, detergent or 5% ammonia, using a soft
    long fibre brush if necessary.
    * Rinse with water.
    * If required, remove water with overlapping strokes, doing work from top
    to bottom.
    For heavier soiling, pressure jet cleaning will not be appropriate. Hosing with water and detergent, and if necessary, gentle rubbing with a soft cloth sprinkled with fine calcium carbonate powder (200 mesh or finer), could be tried, but this could take the gloss off the paint if done too vigorously or frequently and skilled cleaning advice should be sought.
