Use and Maintenance


Type material

Stainless Steel Sink
These fall into two categories: single-casting models made using a single sheet, with shallower tubs and thinner steel, and those with welded tubs which are deeper, squarer and therefore offer a greater capacity.
Steel sinks tend to show water marks and limescale deposits easily; however, these can be removed using the special products currently available on the market. An embossed or "scratch-resistant" finish consisting of raised geometric patterns on the surface is also available; this increases the scratch resistance of the sink, but makes cleaning more difficult.

Resin Sink
Made using cast resins and polymeric minerals.  This is resistant to chemical agents and stains, but may lose elasticity over time and break if subjected to thermal shocks (a sudden switch from cold to hot water, for example); it is initially very easy to clean, but this process becomes more complicated over time as micro-scratches form in the surface and capture dirt. It is not easy to recycle. For detailed information about the features of the various sink materials, please refer to the worktops section.

Cleaning recommendations

For sinks available in various materials (steel or synthetic resins such as fragranite, cristalite or ekotek), follow the instructions for worktops made from the same material. Do not leave opened packets, bottles of detergent or other acidic products underneath stainless steel sinks, as the fumes released may cause rusting and corrosion.
