The BIRKENSTOCK Polishing Cloth is made of 100% cotton and has a soft surface that works gently with the leather. The fabric effectively removes dust and allows the BIRKENSTOCK Leather Conditioner to be applied evenly, so the material remains smooth and sleek. The procedure is simple: apply the conditioner to a cloth and lightly massage the skin in circular motions, then polish. The cloth is suitable for both smooth and oiled nubuck leathers and helps to maintain the original shape of the shoe without unnecessary reinforcement of the surface.
