As with other countertop materials, stainless steel offers some options for edge finishes. The most common is a 1.5-inch wrap that mimics the depth of a standard countertop, using an eased square edge. Other choices are a beveled edge, bullnosed or rounded edge, or no metal on the edge at all.
Next, do a light scrub with baking soda and vinegar using a non-abrasive material or scrub brush in the direction of the grain. Never use abrasive cleaners, steel wool or a rough kitchen scrubbie to clean stainless steel. Use a clean damp dish cloth to rinse the surface and then dry it with a paper towel or microfiber cloth, also in the direction of the grain. This helps prevent streaking.
To remove lime scale, it‘s best to use diluted vinegar and for coffee deposits, clean the area with baking soda. Using chloride-free glass cleaner is also another way to get a quick shine. Professional installation is recommended unless you are experienced in construction and kitchen installations. That said, whether you can do it yourself or not also depends on the complexity of your project and how big it is.
