Vachetta Leather Redox Treatment 2.8

Vachetta Leather Redox Treatment 2.8 by Leather Doctor is an oxidation-reduction reactor for lightening, browning, suntanning, and water discoloration.

What is Vachetta Leather?

• Vachetta is a vegetable-tanned leather, also known as saddlery, bridle, equestrian, craft, or tooling leather.
• It is commonly used in bags, boots, wallets, and furniture.
• Popularized by brands like Louis Vuitton, Vachetta leather is known for its natural, untreated appearance that develops a patina over time.

Why Does Vachetta Brown Over Time?

• When new, Vachetta leather has a pale biscuit color.
• However, exposure to sunlight and UV light causes the natural vegetable tannins to oxidize.
• Resulting in a suntanned effect, similar to how human skin tans under the sun.

What Causes Water Spotting on Vachetta?

• Vachetta has a lower pH-neutral point (between 3 and 4) than most other leather types.
• When exposed to solutions above pH 7, it reacts like litmus paper, developing water spots due to pH sensitivity.

Preventing and Managing Cracks in Vachetta

• Vachetta leather is more prone to dryness due to its high fat and oil absorption needs.
• If existing cracks are present, it means the leather is already dehydrated.
• Attempting another wet-to-dry conditioning without replenishing fat and oil can further accentuate cracks.
• Fatliquor 5.0 should be applied to restore softness, elasticity and prevent further damage.
• Drying Vachetta from a wet state without sufficient fat and oil content is not recommended.

How to Remove Dark Greasy Stains from Vachetta?

• Darkened, greasy stains, especially in high-contact areas like bag handles, require a thorough degreasing process:

1. Apply Degreaser 2.2 to break down the grease.
2. Rinse with Acidifier 2.0 to restore the leather’s pH balance.
3. Use Brush 1 and Eraser 4 for enhanced frictional removal of greasy soiling.

When to Soften Vachetta Leather?

• Softening Vachetta begins when the leather is still damp from Rinse 3.0 or Acidifier 2.0:

1. Apply Hydrator 3.3 to relax the leather fibers. 
2. Follow with Fatliquor 5.0 to replenish essential fat and oil, restoring softness and flexibility.

Treating Browning Vachetta with Redox Treatment

• Browning in Vachetta requires an oxidation-reduction (Redox) reaction treatment. This should only be performed when the leather is dry.

What Is an Oxidation-Reduction (Redox) Reactor in Leather Care?

In leather restoration, a redox system or process is used to reverse oxidation damage or lighten darkened/discolored areas of leather without harming the material.

Over time, leather darkens due to:

• Oxidation of fats/oils (from skin contact or conditioners),
• Exposure to UV light,
• Environmental pollutants,

A redox system uses both oxidation and reduction reactions to safely bleach out unwanted discoloration, remove stains, or reverse darkening. 

Example: Leather Doctor® Lightening Process

Let’s say a vegetable-tanned leather bag has oxidized and turned dark due to age and skin oils:

1. Degreaser 2.2: To remove oxidized oils.
2. Acidifier 2.0 & Hydrator 3.3: Rebalances the pH and hydrates the collagen fibers.
3. Fatliquor 5.0: Reintroduces healthy oils and restores suppleness.
4. Vachetta 2.8: A specialty product designed to break down organic discoloration (oxidation stage).

This sequence acts like a controlled redox reactor—done by hand, but with precise chemistry and order.

Instruction:

1. Concentrate is mixed 1:3 with distilled water before use.
2. Apply Vachetta 2.8 for a darkening effect.
3. Extract excess product with a dry towel to achieve an even appearance.
4. Allow the leather to dry and inspect the results.
5. Perform treatment after fat liquoring if the leather has a high fat and oil content.
6. Wipe off surface residue with Rinse 3.0 and let dry to complete the treatment. 

By following these steps, Vachetta leather can be effectively restored and maintained, ensuring its suppleness, beauty and longevity.
