>>> Want can I do next the stain still there :-( as you can see in the three pcs I upload. What would you recommend, do I start with the degreaser again?).
A dark stain as shown on absorbent vachetta leathers means that the stain is penetrated and usually oil based if it still shown when the leather is dry. It will need repeat of Degreaser-2.2 to penetrate below the stain to emulsify it and Hydrator-3.3 to well to wick the suspended stain to the surface. Rinse-3.0 is for surface rinsing. Hydrator-3.3 has many functions and priority is to help moves suspended soiling within the leather structure.
Technique practice is as follows:
1- Shake the Degreaser-2.2 to gel, transfer apply using a cotton swab to saturate the stain until fully saturated and let to dwell 10 to 30minutes or before it dries.
2- Blot any suspended soiling until paper towel shown clean and dry.
3- Inspect to determine its effectiveness, otherwise repeats as the stain is moving to the surface.
4- When surface appears lighter in appearance, Rinse-3.0 may follow.
5- Deeper suspended soiling need to resurface and is more effective when Hydrator-3.3 is used. This will require soaking or saturating into the depth of the stain to help moves the soiling particulates to the surface, blotting repeatedly while damp or using a “reverse transfer” technique to peel off the soiling particulates when crispy dry then allowing it to deposit on the leather surface. “Reverse Transfer” technique is using a stretchable paper towel that comes with the kit with Hydrator-3.3 and working with leather Brush-1. The principle is to extent the leather surface so that soiling particulates wick through it and peel off when crispy dry.
6- When the stain is fully out from below surface it may appear lighter or discolored, which is part of the successful stain removal over cleaning. This slight discoloration is rectified with Hydrator-3.3 to even out the appearance and is recommended to saturate evenly out to the entire panel or section without leaving out a connecting dry section that may results in rings or marking when dry.
7- Severe discoloration may need the help of Vachetta-2.8 if original stain does shift the protein fiber ionic positive (+ve) charges.
8- Even appearance is also improves when Fatliquor-5.0 is replenished as degreasing also removes the natural fat and oil that contributes to its color intensity.
9- Finally the Protector-D helps in the total appearance as well as imparting a non-stick, rub-resistant surface. It will also rectify some minor surface defects with its healing properties.
As you can see the care of naked, unfinished vachetta leather is very unforgiving due to its nature and will need a pure and holistic approach to it, base on science and logic. Note that all products suffix denotes the pH value of the product. Vachetta an amphoteric leather protein fiber is more pH sensitive than others and success will require some understanding of what leather is, knowledge and patience.
>>> however there is a de coloration ...I will get vachetta 2.8. Do I need the hydrator?
Rectification for discoloration will require the help of Hydrator-3.3 and Vachetta-2.8
