To clean suede trainers, start by using a suede brush or a soft toothbrush to gently brush away any dirt or debris on the surface. Avoid cleaning them when wet and let any mud or moisture dry first to avoid stains. For surface marks and scuffs, use a suede eraser or a clean pencil eraser with gentle back-and- forth motions to lift stains without damaging the fabric. For stubborn stains, lightly dab a cloth with a small amount of suede cleaner, white vinegar, or rubbing alcohol and gently massage the area, then let the suede dry naturally. After cleaning, brush the suede gently to restore its texture and consider applying a suede protectant spray to keep them cleaner longer. Stuffing the trainers with newspaper can help maintain their shape while drying.
