Understanding the chemical nature of a stain is the starting point for every SIC formulation.
A stain is not simply dirt deposited on a surface. It is a physicochemical phenomenon—and that is precisely why some stains resist every attempt to remove them.

At SIC, our R&D work always begins with one fundamental question: what is the chemical nature of the dirt or stain we want to remove? To eliminate a stain effectively, we must first understand it.
