Firstly, we need to establish what type of finish the surface is, EG- is the surface shiny or dull, or does it have lines or a grain (Brush finish)
Once you have established this, each surface finish does require a different cleaning technique.
Restoring a polish finish can be done with following products used with a soft cloth, soapy water to remove dirt and grime, for deeper cleaning use jiff, or aotosol or any stainless-steel cleaning product.
To restore a brush finish we recommend following the same technique as above except rubbing with the line or grain of the stainless.
If this doesn’t bring back the lustre, then replace the rag with a piece of scotch bright and continue to rub the surface with the grain, Do Not rub against the grain or you will add scotches to the surface in different directions
Rinsing will help prevent staining and spotting due to soap residue. Towel-dry the metal to prevent water spots. Fingerprints are one of the biggest complaints about stainless steel.
