Proper care and routine maintenance is the key to keeping stainless steel clean and preserving its sheen.
Always use a clean microfibre cloth and warm water, remembering to wipe the surface in the direction of the grain, followed by a dry microfibre cloth to prevent water marks. For areas with baked on stains, try using warm soapy water with a mild detergent.
Always avoid using steel wool or scourers. As they are typically made of carbon steel, fragments of which will rust onto the stainless steel surface. It will also create fine scratches, spoil the finish and lose its shine.
Polishing stainless steel with oil based cleaners will assist to repel finger prints and restore its lustrous appearance.
