The cleaner works by attracting dirt, surrounding it, making it easy to rinse away. It does not use solvents or acids (citrus) to be effective, resulting in a safe product to use. This simple concept works across all types of finishes, be it, matt, carbon or gloss and leaves a clean, contaminate free surface. Fenwick’s Bike Cleaner is biodegradable and safe to use on anodising, carbon, plastics, rubber and painted surfaces.
