As the world’s largest stainless steel sink manufacturer, Franke are extremely stringent in the quality and standards required from their steel suppliers. Franke stainless steel sinks are made from a premium quality chrome nickel steel, they are highly resistant to staining, rust and corrosion.
Franke have their own cleaning products specifically for the care and maintenance of stainless steel sinks but there are others available in supermarkets and hardware stores such as Shiny Sinks' and Bar Keepers Friend', which when used regularly help to keep your sink in optimum condition.
To avoid rusting stains thoroughly clean and dry your sink and avoid the following:
- The use of plastic bowls for washing up as these cause heavy localised scratching
- Wire wool pads
- Leaving salt or acidic foods such as vinegar, citric fruit juices, mustard or pickles on the surface for any length of time as they can cause corrosion
- Strong acids like denture cleaner
- Abrasive cleaners like bleach
Surface scratches are expected on stainless steel sinks and will become less noticeable over time as they even out, stainless steel sinks look better as they age.
Avoid using a plastic washing up bowl as this will cause the development of regular abrasion marks over the sinks surface due to the continued friction in a specific area of the sink.
Stainless steel sinks cannot rust or corrode under normal domestic use. Discolouration and 'rust' marks on stainless steel sinks are tiny deposits of ferrous particles, such as iron clinging to the sinks surface.
These often occur with new installations when pipework is disturbed as well as from left over water deposits, scouring pads or utensils. They are the result of an outside source rather than coming from the sink itself and unless removed, will rust.
In cases where particles are left or have been able to build up over a period of time, even after several attempts at cleaning some particles may remain. .Unless the particles are completely removed as soon as possible they will return. For stubborn marks you can use a nylon nailbrush to get into the texture of the sink but it can take several attempts to see an improvement or restore the sink to its pristine condition.
