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.

Further questions are welcome

This is after D'Protein & D'Tarnish. When it dried, I used the spatula.

This picture shows above surface removal.

This is after clean, rinse, hydrator & fatliquor. The stains came back.

These pictures show the stains came back from beneath the surface, not a surprise when dealing with absorbent leathers, because we never know how deep it had gone below the surface. Each successive repeat cleaning will reduce the resurfacing, until the stains beneath the surface is completely exhausted.

For our understanding, this wicking-up phenomenal will not happen to non-absorbent pigmented leathers.
