Bought this sofa new in '94 for $3000. Pretty sure it is naked leather, or at least naked with minimal protection. Had a salt water tank behind it (and south window. lots of salt spilled on back. Various old protein stains.
Very dry and faded. Some roughness on seat from dog scratching.
Soooo.... What are some recommendations and prices for restore? Please comment and email product price for full restore for six foot sofa.

Picture #2
This picture shows the contrasting color of Aniline leather between used and unused.
To bring it back to its original beauty may require both restoration to its structure to provide softness, suppleness and strength and its appearance with a fresh new matching dyestuff with its matching topcoat, besides the stain removal and restorative cleaning processes.

Picture #1
This picture shows worn topcoat (Topcoat-79Gloss), thus lost the intensity of the color that is enhanced by the topcoat. Various old proteins stains may have coagulated and may feel stiffer than other non coagulating stains require a leather protein removal (d’Protein-11.0 with its neutralizing counterpart with either Acidifier-2.0 or d’Tarnish-1.3 for protein blood stain).

Picture #3
This picture shows a dark perhaps penetrated grease stains that may require (Degreaser-2.2 > Rinse-3.0) to cause the stain to wick to the surface to be extracted. Dog scratching repairs will depends how deep it has gone into the structure – structure repairs to strengthen the leather would require Impregnator-26 and surface flap repairs would require leather Bond-3D. However all such repairs may appear darker in tone just like natural scars we often seen in aniline leathers. Roughness would be repair with fine sandpaper (1500 grit)

Picture #4
This picture shows fugitive dyestuff cause by alkaline overexposure. Salt water normally has a pH of around 8, while the pH neutral of the leather is around 4. Thus the stains are 10’000 times alkaline overexpose. This has to be neutralized to the pH neutral to around 4. By doing so the blotchiness will even out, the tackiness if any will return to a squeaky healthy feel. The entire leather structure needs to be hydrated to even out the leather constituents by redistribution and reducing the interfacial tension at the same time. The hydrating process will also reactivate the dormant dyestuff from within the leather structure to resurface for a more even appearance. Hydrating (Hydrator-3.3) would also take care of the very dry and faded to be further fatliquor (Fatliquor-5.0)
