    >>> Roger, do you think we can restore this LV purse to new condition?

    Thanks to the new formulated leather-safe Vachetta-2.8 specially designed for such purposes.

    Tips:
    1. Apply products to the stain areas, agitates with a horsehair Brush-1 and repeat extract until towel shows clean (it depends how deep it has penetrated so a deep saturating will ensure reaching to its depth).

    2. When no more stain shows on the towel – Saturate the entire straps with an even appearance to avoid any surprise rings or marks.

    3. Leave for complete dry for inspection.

    4. Repeat above 1, 2, and 3 as necessary as stains may resurface for another inspection.

    5. Leather rejuvenating follows with complete saturating with Hydrator-3.3 for an even appearance and inspection for surface tension prior to Fatliquor-5.0.

    6. Ensure all wet process produce an even appearance, otherwise need to correct prior to the next step.

    7. Protector-D recommended healing the surface with a draggy feel.

    Use this Vachetta (V) Leather Problem Solving Guide as reference.

    Leather Doctor Kit V6 – Vachetta Leather Grease/Ink/Dye/Browning Removal Kit
    http://www.leatherdoctor.com/servlet...-V6/Categories

    Leather Doctor® Kit V6 is a combination problem solving kit that includes products from Kit V5.dr, Kit V5.ds and Kit V3. Common stains encounter in the course of vachetta leathers lifetime includes the darkening effect from neglected body oil, grease and sweat contact, the occasion ink and dye transfer, and the browning from liquid and sun tanning seasoning effect just like our skin. The protein leather fiber is an ionic positive (+ve) “amphoteric” material thus pH sensitive to influence by alkaline solution shifting ionic negative (-ve), even water with a pH of 7 often discolors or browns it. Its other non-amphoteric leather constituents like the tanning agent and the fatliquor remains ionic negative (-ve), hence just like a magnet – “like poles repel”, breaking of the hydrogen bond between them, the leather denatures and in extreme cases revert to rawhide. This adverse contamination is rectify by Degreaser-2.2 > Acidifier-2.0 system, both to simultaneously degrease and protonate the protein fiber ionic positive (+ve) to its pH chemistry integrity. Ballpoint, printing ink, dye transfer, gum, sticky substance and accumulated soiling will require the penetrating, lubricating and suspending power of Prep-4.4 follows with Clean-3.8 to remove the sticky residue and Rinse-3.0 to a healthy squeaky feel. Browning from liquid stain or sun tanning is eliminated or reduced by chemical reaction from Vachetta-2.8 when dry. The above describe the three common class of stain removal. Leather rejuvenating mandatory sequence follows to soften and strength the leather from stiffness that may leads to cracking when flexed. Among leather finishes type, vachetta leathers is the most fatliquor (fat, oil and water) thirsty and will require more fatliquor to soften it then chrome-tanned leathers. In order to lubricate each fibril within the leather structure behaving like millions of interconnecting hinges the fat and oil has to be hydrogen bonded to the fibrils. This is accomplished by preconditioning the leather structure with Hydrator-3.3 effectively prior to faliquor replenishing it with Fatliquor-5.0 in between drying cycle until fully saturated. Natural slow drying in between application produces softer leather. Protecting the leather with Protector-D reduces wear to the grain of the leather, conceal scuff with its healing properties that also allows transpiration to take place or breaths naturally. Note that the mentioned products suffix numbers denotes its pH value in this holistic approach to removing the common problems associated with vachetta, saddlery and veg-tan leathers.
    This kit comes with reduced weight option to save on shipping thus the 250ml concentrate ratio such as Acidifier-2.0, Clean-3.8, Rinse-3.0, Hydrator-3.3 and Fatliquor-5.0 has to be cut or filled up with distilled water prior to use.
