Care of Stainless Steel Sinks
Stainless steel sinks should be rinsed and dried after each use, and wiped with a mild cleaner approximately once per week. They actually thrive with frequent cleaning, and, unlike some other materials, it is impossible to "wear out" stainless steel sinks by excessive cleaning.
You can use typical household cleaners to clean. These cleaners can easily be used with warm water, sponges or clean cloths. Since most soaps and detergents contain chlorides, once cleaning is complete, rinse the surface immediately to prevent corrosion. Rinsing in clean hot water leaves stainless steel shiny and germ free, all ready for the next use.
Lastly, it is advisable to wipe the surface completely with clean dry towels so that the water does not evaporate and leave water spots. Avoid the use of oily rags or greasy cloths when wiping the surface. Regularly drying your sink works wonders to prevent water and surface rust marks.
If you want it to be sparkle, club soda will do the sparkle trick as well. As always, dry with soft cloth to prevent water spots and surface rust.
