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 with water (preferably deionised water) and dry. Deionised water reduces the risk of water
staining marks.

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.

- 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 contamina-
tion, 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.

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, espe-
cially in hard water areas may be advisable. The use of deionised water will prevent the formation of hard
water staining.
