    Pictures #1, #3 & #4 show browning stains.
    These unknown stain may derived from 2 main sources, an alkaline solution or solution that contains tannin from fruits juices or sugar that browns.

    Solution to these problem could be easily corrected with Acidifier-2.0 (pH 2.0) if the sources of the stains are pH related.

    If the stains are from tannin derived, that is juices from plants and vegetation, it will require the help of d'Tannin-3.5 (pH 3.5) to chemically removed the tannin stains.

    Pictures #2 & #5 shows black marks.
    These could be ink or dyestuff derived and will require the help of Prep-4.4 (pH 4.4) to disperse the stains with further help of Hydrator-3.3 (pH 3.3) to wick them out of the leather fiber.

    Pictures #5 & #6 shows worn to the leather and this has nothing to do with cleaning. However, body oil, grease and sweat need to be extracted from these worn areas with Degreaser-2.2 follows with either Rinse-3.0 or Acidifier-2.0. The only practical approach to the worn areas then is to use a fine 1000/2000grit sanding to smoothen the nap. Take note that the deeper the leather the coarser will be the fiber. So when sanding, only remove the surface naps and not go deeper. The worn surface of the leather could be improve by applying Protector-D to conceal and smoothen it (other repairs will cause a darkening effect).

    Refer to this Vachetta Leather Problem Solving Guide for details:

    Start with this Degreaser Kit with add-on to the other dye and tannin problems.

    Leather Doctor Kit V5.dr – Leather Degreaser Kit
    Leather Doctor® Kit V5.dr, vachetta, saddlery and veg-tan leather degreaser kit is an innovative leather-safe degreasing system for removing grease and sweat contamination. When sweat accumulates and ages it shift alkaline, besides the apparent darkening effect it will also impart a sticky feel to the leather. Leather is composed of protein fiber with other leather constituents like the tanning agents and the fatliquor. The tanning agent preserves the leather while the fatliquor softens it. The protein fiber is amphoteric while the other component is non-amphoteric. They come together by hydrogen bonding. When the pH of the leather rises due to the sweat, the protein fiber begins to shift ionic negative and breaks bond with the ionic negative tanning agent and the fatliquor. The protein fiber loosing the ionic attraction from the tannin agent denatures and revert the leather to rawhide as experience with tackiness or stickiness in extreme cases. The stiffness of the leather is due to the loss of the fatliquor that lubricates the fibers thus the fiber becomes stick together and when flex cracks. The darkening effect is partially contributes by high pH exposure, as alkaline darkens and acidity lightens the appearance of leather. To rectify the compound problem the grease and sweat contamination is remove. The protein fiber is degreased and recharged ionic positive below its iso-electric point (pI) by using Degreaser-2.2 follows by Acidifier-2.0. This combination degreasing and rinsing process should improve the darkening effect while reversing the leather to a healthy squeaky feel. Hydrator-3.3 helps rectify alkaline overexposure areas by facilitating colloidal water movement to redistribute the leather constituents from surrounding areas, while purging foreign contamination to resurface and charging the protein fiber below its iso-electric point (pI) ionic positive to hydrogen bond with the ionic negative fatliquor more effectively. Fat and oil is replenished with Fatliquor-5.0 to return the leather for softness and suppleness when dry. Protector-D heals and conceals scuff and abrasion marks; imparts a rub resistant draggy-feel against friction rubs and shield against sticky soiling while prolonging the appearance of the leather longer. Note that the mentioned products suffix numbers denotes its pH value for a safer degreasing approach to pH sensitive leather. Leather is an amphoteric material and shifting of it pH value obliviously causes the leather to darkens, denature and reverts to rawhide.
