In general the minimum care is needed to maintain stainless steel in its original condition, however, in certain conditions particularly where there is exposure to salt air, a routine cleaning programme will maximise performance and service life. The solutions to specific problems are shown in the table. A number of rules should be noted:
Do:
- Use the mildest cleaning procedure that will do the job effectively.
- Follow the polishing lines when using abrasive cleaners.
- Rinse thoroughly after cleaning operation.
- Wipe dry to avoid water marks.
Dont:
- Use steel scrapers or knives in removing heavy dirt deposits. This may cause rust spots, use wood, plastic or stainless steel tools.
- Allow chemical sterilisers, bleaching agents or any solution containing chlorides to remain in prolonged contact with stainless steel.
Organic colour coatings as applied by A.S. Hardware Ltd. should be cleaned and maintained on a regular basis. The frequency of such cleaning will depend on a number of factors which include the following:
- The geographical location of the building..
- The environment surrounding the buildings, i.e. marine, industrial, alkaline/acidic, etc.
- Levels of atmospheric pollution.
- Prevailing wind.
- Protection of the building by other buildings.
- Possibility of airborne debris causing erosive wear of the coating.
The best method of cleaning is by regular washing of the coating using a solution of warm water and mild detergent (e.g. 5% Teepol Solution). All surfaces should be cleaned using a soft cloth or sponge, using nothing harsher than natural bristle brushes.
In industrial environments the normal frequency of cleaning should be at not more than three monthly intervals. Should there be a high atmospheric pollution the period between cleaning should be reduced.
Where the atmosphere is deemed 'rural' or 'normal' then the period of cleaning may be extended to six monthly periods.
Polished brass material will require polishing with a suitable metal polish, e.g. 'Brasso' or similar.
Where a stove lacquered finish is applicable then the surface should be given a regular dusting and wipe down with a damp cloth, followed when dry by a wax polish.
Lacquered finishes are not indestructible and if the finish breaks down or wears away then the metal should be maintained as for polished brass.
Timber door furniture should be treated with a good quality waxing product at regular intervals.
