Cleaning and Maintenance of Stainless Steel surfaces
Mortar and cement splashes can be treated with a solution containing a small amount of phosphoric acid.

marks.
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.

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.
On "grained" directional finishes, the direction of cleaning strokes should be along the grain and not
across it.
Where water has been used for cleaning or rinsing, wiping the surface dry to prevent watermarks,
especially in hard water areas may be advisable. The use of deionised water will prevent the formation
of hard water staining.

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.
