This great cleanser is specially made to clean unfinished leathers like Louis Vuitton's Vachetta. The cleanser does not cause darkening the way others do. Apply the cleanser evenly with a soft, high quality cloth. Let dry naturally. Attikk recommends using a leather hydrator after cleansing, since repeated cleaning can cause dehydration, which can lead to cracking. Test product for any adverse reactions in an inconspicuous area first. Be especially aware if the leather has previously been treated, altered, painted etc. Can cause irritation. Avoid contact with eyes, mouth and skin. Keep away from children. If product gets into eyes, rinse thoroughly with clean water and seek medical advice. Perfect for Louis Vuitton's Vachetta leather! The leather may darken slightly when the product is applied, but should return to its original colour when dried.
