STEEL Simply wipe with a slightly damp soft cloth or the soft side of a sponge, to bring back the shine. LEATHER Calfskin leather is a natural material that may have some natural imperfections. These are completely normal and reflect the authenticity of the leather. Recommendations: - Do not get the leather wet and do not put your piece in the dishwasher. - Do not expose leather to direct sunlight or to sources of heat. - Do not use solvent-based stain removers such as turpentine or benzine, nor shoe creams or floor waxes. - Before using any cleaning product suitable for leather, test it on an inconspicuous area. Do not apply directly to the leather; use a cloth. - Oily stains: leather generally absorbs oily stains without leaving a trace. If any trace remains, remove it with a stain remover. Fresh, visible stains should be dabbed immediately with a cloth and then wiped dry with a paper towel. - Alcohol stains: wipe immediately with a slightly damp cloth. - Scratches: use a hand cream with a glycerine content of at least 5%. - Pen marks: remove immediately using a stain remover. - Heavily soiled areas: first use a special leather cleaning-foam. If the marks persist, use a stain remover.
