To keep the sink vessel looking great through much use over the years, it is wise to take the time to clean and care for it properly, based on the type of material it is created from. The glass vessels will keep a bright shine with just glass cleaner or vinegar and water. Maintaining a granite sink is best with a special cleanser that can be found in any home goods store. Marble can be protected from acidic products with the use of a special sealant that can be applied two times a year.
