Cleaning and Maintenance of Stainless Steel surfaces
Mortar and cement splashes can be treated with a solution containing a small amount of phosphoric acid. Rinse
withwater(preferablydeionisedwater)anddry.Deionisedwaterreducestheriskofwaterstainingmarks.
Proprietary products are available from specialists finishing companies. Never allow mortar removers or diluted
hydrochloric acid to be used on stainless steel. If they have accidentally been applied to or spilt over the stainless
steel, rinse generously with fresh water.
- Brushed finishes, which are a popular choice for interiors, may show finger marks in the period immediately after
installation, but the visibility of the marking should become less evident after the first few cleaning operations.
- To remove fingerprints and other marks, soapy water or a mild detergent are usually safe and successful.
- Mirror-polished stainless steel can be cleaned with glass cleansers. These products should be selected chloride-
free.
- Scouring powers should not be used as these products can leave permanent scratches on stainless steel
surfaces.
- Alternatively, use a proprietary stainless steel cleaner containing phosphoric acid to remove contamination, rinse
with deionised water and dry. It is advisable that the entire surface of the component is treated so that a patchy
appearance is avoided.
-CleanersthatshouldNOTbeusedonstainlesssteelsinclude:
• chloride-containing cleansers, especially those containing hydrochloric acid,
• hypochlorite bleaches should not be used on stainless steels; if applied accidentally or spilt on stainless steel
surfaces, should be rinsed off immediately with liberal amounts of fresh water,
• silver-cleaners must not be used on stainless steel
A damp cloth or chamois leather will usually be suitable for removing normal soiling, fingerprints, etc.
For more stubborn dirt, nylon pads are usually satisfactory.
Non-stainless steel based scouring pads, cleaning wool or wire brushes must not be used on stainless steel.
Apart from scratching the surface, these pads can leave carbon steel deposits on the stainless surface, which can
subsequently develop into rust spots, if the surface becomes wet.

(i.e. carbon) steel before. Cleaning materials for use on stainless steel items should preferably be reserved
exclusively for that purpose.
Cleaning should be done before there is a visible build up of soiling or finger-marking, so that the effort and cost of
cleaning is minimised along with the risk of marking or altering the appearance of the surfaces.

- Sur les finitions en mat, qui sont souvent choisies pour les intérieurs, des traces de doigts peuvent apparaître
durant la période suivant immédiatement l'installation, mais celles-ci disparaîtront progressivement après
quelques nettoyages.
- Pour effacer les traces de doigts et autres marques, l'utilisation d'eau savonneuse ou d'un détergent léger est
habituellement efficace et sûre.
