Clean your stainless steel sink with dish detergent and hot water daily. Rub the soapy solution in the direction of the grain with a nonabrasive soft sponge or towel to remove food remnants and soap build up. Refrain from using abrasive scrub brushes or steel wool, as they can scratch and mar the stainless steel finish. Rinse the sink with water and dry with a soft towel.
Spray a nonabrasive and antibacterial household cleaner or stainless steel cleaner on the sink surfaces three to four times a week to remove germs and soap scum. Do not use a cleaner with bleach or chloride because such ingredients can corrode and discolor stainless steel sinks. Scrub the cleaner in the direction of the grain with a soft, nonabrasive sponge or cloth. Rinse and dry the sink.
Dry the sink with a soft towel, if wet. Pour stainless steel polish or conditioner on a soft sponge or cloth, and rub it onto the sink surfaces in the direction of the grain to create sheen and to buff out scratches. Repeat this process weekly.
