    Default Louis Vuitton 12 years old bag developed a dark patina. . . and a black stain.

    My LV bag is 12 years old and until recently was untouched or treated.

    It had developed a dark patina, with darker patches from where it had been carried.

    I then spilled a bottle of apple juice inside and in desperation (knowing it was pretty much wrecked anyway) I tossed it in the washing machine with some wool wash.

    Surprisingly it came out relatively ok, but I know I need to probably give it some major tlc to replace oils etc in the leather.

    I did give it some leather conditioner & beeswax leather balm - but I'm unhappy with how this has left the leather and would prefer to clean this off and do it 'right', having read your info.

    Other than this, there is a black stain on the vachetta base, which may be ink, or liquid eyeliner.

    No idea what it is or how it got there sadly.

    Let me know when this Kit arrive and you are ready to start. . .

    Leather Doctor® Kit V7 design for the care of Louis Vuitton (LV) bags is a combination problem solving kit that is an upgrade from Kit V6 with an addition of Protector-B+ for the simulated leather to impart a non-stick rub-resistant buttery-feel with a classic leather scent. 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 (emulsified 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 leathers.
