There's no single process for every surface. Each one is assessed individually — fiber or leather type, level of soiling, material sensitivity — and from that we determine the level of treatment required: from a standard deep clean to more specialized, multi-stage protocols for particularly delicate or heavily soiled surfaces.
In every case, the process includes mechanically removing trapped dust before any wet application, controlled use of cleaning products matched to the material, and finishing with sanitization — always adjusting intensity and steps to the condition of that specific surface.
