​Quartz sink stains are usually caused by surface deposits rather than permanent material damage. In most kitchens, discoloration comes from mineral residue, grease films, metal transfer, or food pigments that remain on the surface too long.

Quartz sinks are becoming increasingly popular in modern kitchens due to their durability, stylish appearance, and resistance to stains. However, like all kitchen fixtures, they require regular cleaning and proper care to maintain their beauty and functionality.
