Leather Identification:
This leather is identified as Vegetable-Tanned Leather by sight; only to be confirmed with a testing of Stripper-2.3 for presence of aniline dyestuff. This leather is also known as Vachetta Leathers made popular by Louis Vuitton and Coach, leather goods maker. The pH neutral of this leather is lower than the typical chrome tanned leathers; thus is more pH sensitive among all the different tanning types of leather. Besides, heat and water tolerance level is lower than the chrome tanned; and is fatliquor thirsty.
Urine Stains:
Urine stains with its urea contents that when fermented by the natural bacteria from the atmosphere will shift its pH alkaline. The transformed ammonic contamination that remains, may further basify the protein fibers anionic (-) that cause a pole repelling of the leather other anionic (-) constituents, like the tanning agent and the fatliquor. This resulted in concentrated ring marks where the fugitive’s leather constituents move away from the center of exposure together with the staining residues. Prolong hydrolysation from atmospheric moisture may result in the sliminess or tackiness of the stain when test with wet fingertips. That is the natural process of denaturing the leather that may result in dry rot in extreme cases; where one can put their finger through the leather.
Beer Stain:
The only problem with beer stain is the tannin color; especially with such skin-tone leather color. Unlike the urine stains that cause a denaturing effect to the leather by breaking the hydrogen-bonding between the protein fibers and the leather constituents and reverting back to rawhide; there is no such fear from beer stains; except, it’s to be removed with a pH 3.5 leather-safe tannin stain remover.
Protein Stains:
Such stains from body fluid and foodstuff have a coagulating effect that binds the leather fibers tenaciously; when penetrated has a stiffening effect. Only with a high pH of 11.0 leather protein stain remover to effectively soften up the stains to be extracted and neutralized thereafter accordingly.
Body Oil and Grease:
When it’s penetrated it will require the works of a low pH 2.2 degreaser to demulsify it.
Objective:
With these complexity of stains that have contaminated the leather; it is how we can effectively neutralize, demulsify and bleaching the unwanted stain yet not to upset the chemistry integrity of the leather; but strengthening and rejuvenating it, what’s been weaken or lost through the removing process, especially its pH value and the fatliquor – the lifeblood of leather – where the characteristics of suppleness and strength lies – lacking as we can see in picture #3 – the ripping of the belt!
The recommended Sequence of Process:
Step 1: Urine Decontamination:
Continuous sequence as follows: d’Protein-11.0 > d’Urine-2.1 > Rinse-3.0.
Step 2: Degreasing:
Continuous sequence as follows: Degreaser-2.2 > Rinse-3.0
Step 3: Tannin Beer Stain Removal:
Continuous sequence as follows: d’Tannin-3.5 > Rinse-3.0
Step 4: Hydration to Purge Penetrated Foreign Contamination:
Continuous sequence as follows: Hydrator-3.3 > Tissue Surface Extension > Cling Wrapper > Overnight Dwell > Remove Cling Wrapper > Natural Air Dry > Remove Tissue Extension > Inspection – repeat as necessary. Tips – effective hydrating should have an oozing effect when the leather is lightly squeezed between finger and thumb.
Step 5: Leather Rejuvenating:
Fatliquor-5.0 – the more, the deeper the color tone; the stronger its tensile strength will be.
Step 6: Topcoating to Match:
Choice of Topcoat Aniline - 79G (gloss), 59M (waxy-matte) or 89N (natural).
Step 7: Non-Stick, Rub-Resistant Protector:
Choice to match topcoat - Leather Scent-B (buttery to match 79G), Scent-W (waxy to match 59M) or Scent-S (silky to match 89N) or Scent-D (draggy for the naked original).
Here are the kits for such leather care and problems solving solutions.
