This leather type is unmistakably Aniline as shown from pictures. The Aniline Problem Solving Guide will show the proceeding steps on how blood stains are to be removed. It will require a specialty leather cleaner with a high pH of 11.0 to break down the coagulation of the protein stains. It would be very laborious to work them out as the old hardened stain has an affinity with the protein leather fibers. This requires gentle agitation with cotton swab and/or leather Spatula-6 to help release the tenacious stains. The residual rusty stain is what d’Tarnish-1.3 is developed for, besides neutralizing the high pH of the protein cleaner. The effective working result is only realized when the stain is completely dry; thereafter rinse off residue with Rinse-3.0.
As for the repair of the scratches – Topcoat Aniline-79G is recommended. However it is recommended that the leather structure is hydrated and fatliquored prior to topcoat it.
