>>> heres a vachetta chair
This is a top-coated Vachetta (In upholstery the name “Vachetta” is seldom used, rather calling them as unfinished vegetable-tanned leather). This piece is a “Finished Vegetable-Tanned” leather.
So the topcoated damaged areas are exposed, thus can be treated as “Vachetta” or “Unfinished Veg-Tan”.
Name is not as important as how it is finished and how to restore it back to the original..
>>> most of the browning is from sweat and oily substances
A recommended degreasing and pH balancing to reduce the browning is as follows:
Degreaser-2.2 > Acidifier-2.0 > [continue without getting it too dry with] > Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 > [leave to slow dry then proceed with] > Vachetta-2.8 [Inspect when dry] > Tannin-3.5 [ to remove tannin stain like coffee or tea] > Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 > [Inspection] AnilineTop-76G [Deteriorated topcoat is sanded off with new application].
Tips:
Veg-Tan leathers unfinished (Vachetta) and finished are very thirsty of Fatliquor-5.0.
Make sure it is well replenished up to 15% fat and oil content when dry, otherwise, if left to dry will leads to magnified cracking.
