After rinsing any residue off of the Ecoprinted leather, return the moisture by using Honey Leather conditioner on the grain side of your piece. I like to do it before I turn it into a leather product. Pour a small amount of the conditioner onto a dry cloth and apply a thin coat over the grain side of the leather. Let dry 2 hours and then buff. The flesh side can be conditioned with leather conditioning sprays designed for suede.
