Suede, Leather and Silk can only be cleaned with neutral cleaning agents and detergents. Any harsh cleaning agents such as Alkaline or Acid-based chemicals will affect the fabric or skin texture and dyes. Therefore stain removal results are limited to within these parameters and the best possible result is achieved without damage to the garment.
Any areas of the garment that are exposed to constant wear and tear (collars, cuffs, elasticised hems, underarms etc.) will inevitably have a different post clean result. This is due to the fact that these areas will be scarred and not soiled. e.g. pile damage, general fabric wear or colour loss.
