Leather type is most probably absorbent lambskin and looks like the stain is penetrated beneath the surface.
The possible stain type could be as follows and treated accordingly, for unknown stain the only solution is to treat them in priority with an intelligent guess. When removal proves to be futile the best option is to redye to camouflage the stain accordingly.
a) Oil or grease related stains that darkens the leather.
b) Liquid stain that contains tannin coloring, such as beverages, wine, coffee or tea.
c) Color transfer from plastic bag or other material.

Leather Doctor Kit A5.dr – Aniline Leather Degreaser Kit
Leather DoctorŽ Kit A5.dr, aniline leather degreaser kit is designed for routine degreasing from preventing topcoat and dyestuff finishes damages especially to the headrest and armrest areas with most of bare body contacts. Topcoat and dyestuff refinishing products are found in Kit A6.tc and Kit A7.cl respectively. Preventive regular surface degreasing is preferred over corrective penetrated degreasing as most often, the topcoat is damaged and in severe cases, the dyestuff break bonds with the protein fiber. Preventive degreasing is done before a penetrating darkening effect manifest. Degreaser-2.2 is a waterbased (pH 2.2) multifunctional degreaser that besides emulsifying the greasy contamination, it controls dye bleeding and charging the protein fiber ionic positive for strengthening the attraction between the ionic negative tanning agent, dyestuff and fatliquor. Deflocculated and suspended soiling is towel extracted, and then follows with Rinse-3.0 to a healthy squeak. Hydrator-3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fat and oil replenishing. Fat and oil is replenished with Fatliquor-5.0 to rejuvenate the leather for the desired suppleness when dry. Protector-B+ imparts a non-stick rub-resistant protection with a buttery-feel that shield against sticky soiling and reduce friction noises. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe aniline leathers degreasing system.

Leather Doctor Kit A7.cl – Aniline Leather Dye Refinishing Kit
Leather DoctorŽ Kit A7.cl, aniline leather dye refinishing kit is designed for dyestuff and topcoat refinishing from the simple sunlight fading to the severely sweat damages from body oil and grease. Most severely penetrated, prolonged and neglected stains show a darkening effect with a sticky feel have its topcoat and dyestuff probably deteriorated by the sweat. When the stain feels sticky, it is a sign of leather denaturing and reverting to rawhide from breaking of bonds with the tanning agent. When sign of color is transfer to a white towel, it indicates that the dyestuff has also break bonds with the protein fiber. When leather is stiff or show signs of whitish residue migrating, it shows that the fatliquor is breaking bonds as well with the protein fiber. The main component of the leather protein fiber is amphoteric while the other constituents are not; shifting of the pH mainly caused from sweat to alkalinity affects the pH imbalance. To revert from denaturing into rawhide prior to topcoat refinishing, contaminated alkaline soiling is removed with Degreaser-2.2, a waterbased (pH 2.2) multifunctional degreaser that emulsifies greasy contamination besides controlling dye bleeding and charging the protein fiber ionic positive for strengthening the attraction between the ionic negative tanning agent, dyestuff and fatliquor. Deflocculated and suspended soiling is towel extracted, thereafter rinse and pH balanced with Acidifier-2.0 to prevent the leather from reverting to rawhide. When leather feels sticky or slimy it is a sign of leather denaturing, a squeaky feel when wet is a sign of a healthy leather. Hydrator-3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fat and oil replenishing.
