I discovered this simple cleaning tip by accident. For a simple, easy and inexpensive way to clean and shine your stainless steel sink; try liquid dishwasher detergent. - such as Cascade, regular or gel. Store brands work just as well. Start by rinsing sink, allow it to air dry, or use paper towels. Coat entire surface with d/w detergent;,allow to dry completely. Rinse with clean water; using a soft cloth. (You may use a damp tooth brush dipped in clean water to get into tight areas and around drain. *Buff dry with soft dry cloth. ***This method will also remove old coffee and rea stain that build up over time.
