Product Overview

Aniline Waxy Matte Leather Dye Refinishing Kit AM7.cl by Leather Doctor degrease, acidify, clean, rinse, hydrate, fatliquor, dye, seal, and condition waxed leather.

 Aniline Waxy Matte Leather is a full-grain chrome-tanned leather known for its soft hand and transparent aniline-dyed color that enhances its natural beauty. The dye penetrates through to the reverse suede side, creating a rich, natural look with a subtle Sauvage effect. Its fine waxy matte finish is achieved through an emulsion topcoat, which is further protected with a non-stick, rub-resistant conditioner to minimize finish wear.

 As an amphoteric material, Aniline Waxy Matte Leather is pH-sensitive, requiring leather-safe products with a pH between 3 and 5 to prevent potential damage. If exposed to alkaline substances, it must be pH-balanced back to its neutral state (iso-electric point or pI) to maintain its integrity. Additionally, aniline leathers are more UV-sensitive, making periodic hydration and fatliquoring essential for preventing dryness, reviving color vibrancy, and maintaining suppleness to avoid stiffness and cracking.

 Sequence of Steps for Refinishing Waxy Matte Aniline Leather

The refinishing process for Waxy Matte Aniline Leather consists of four key stages:

Cleaning, Hydrating & Fatliquoring, Dyeing & Sealing, and Conditioning.

Each stage is essential for restoring the leather’s appearance, suppleness, and durability.

 Cleaning (Removes Soiling and Prepares Leather Surface)

4-product system is used to remove body oils, grease, sweat, and general soiling while maintaining the leather’s pH integrity:

    • Degreaser 2.2 – Breaks down and emulsifies body oils and grease.
    • Soft 3.8 – Removes general soiling and residual buildup.
    • Rinse 3.0 – Final rinse to remove cleaner residues and return the leather to its optimal pH.
    • Acidifier 2.0 – Neutralizes alkalinity and stabilizes the leather’s pH balance.

  Hydrating & Fatliquoring (Restores Leather Softness and Strength)

2-product system replenishes lost moisture and fatliquor to maintain the leather’s suppleness:

    • Hydrator 3.3 – Rehydrates leather fibers, helping to relax stiffness and improve color saturation.
    • Fatliquor 5.0 – Restores essential fats and oils to prevent cracking and maintain leather flexibility.

 Dyeing & Sealing (Restores Color and Enhances Appearance)

A 4-product system is used to restore color intensity and ensure a natural matte finish:

    • Aniline 21 – A staining dye.
    • Adhesor 73 – A prep and enhance adhesion before color coating.
    • Dye 21 A next-generation transparent surface coating dyestuff.
    • Matte 21 – A waxy matte topcoat to seal and protect the dyed surface while maintaining its original finish.

 Conditioning (Preserves and Enhances Leather Durability)

1-product system creates a non-stick, rub-resistant barrier to reduce wear and prolong the leather’s lifespan:

    •  Protector W or Protector W Plus – A waxy-feel conditioner that enhances resistance to scuffing, abrasion, and soiling, with the Plus version offering a leather scent.

 Leather Acidifier 2.0  by Leather Doctor® is a pH 2.0 acidic rinse designed to control, neutralize, and restore leather’s natural pH balance

 Acidifier 2.0 prevents leather from denaturing, which can lead to bleeding, streaking, tackiness, and structural weakness due to alkaline overexposure

 Acidifier 2.0 Key Benefits:

 Neutralizes alkaline contamination from cleaners, sweat, and body oils
 Prevents dye bleeding and color streaking
 Reduces leather tackiness and improves texture
 Strengthens leather fibers and enhances structural integrity 

 Leather Hydrator 3.3 is a leather-safe pH 3.3 aqueous solution formulated by Leather Doctor® to hydrate, relax, and restore the leather’s internal structure during cleaning, conditioning, and restoration processes - in line with its tannery science-based function:

 It mimics the hydration stage of tannery pre-conditioning to prepare leather for deeper structural rejuvenation.

  Hydrator 3.3 Key Benefits:

 Rehydrates dried, stiff, or collapsed fiber structure

 Restores moisture to the leather’s protein fibers, relaxing them so they can regain flexibility.
 Essential before fatliquoring (with Leather Fatliquor 5.0) so fats and oils can penetrate deeply and bond properly. 

 Displaces and flushes out impuritie 

 Helps suspend and wick out residual body oils, sweat, soiling, or alkaline contamination that may have penetrated the leather.

 Balances pH and readies leather for further treatments

 The mild acidic pH of 3.3 re-aligns the ionic charges of the leather structure, making it receptive to fatliquor and protecting against pH damage.

 Helps reduce stiffness and restore suppleness

 When used alone or in conjunction with fatliquor, Hydrator 3.3 is critical for achieving uniform softness, without patchiness. 

 Tannery science basis

 In professional tanning and retanning, hides are hydrated before fatliquoring or coloring to ensure that treatments penetrate evenly and bond effectively.
 Leather Hydrator 3.3 replicates this essential tannery hydration step at the restoration stage, particularly for dried-out, stiff, or aged leather.

 Aniline Staining Dye 21 by Leather Doctor® is a new-generation, water-based transparent staining dye based on tannery science principles designed specifically for absorbent semi-aniline leathers.

 Aniline 21 Key Features:

 Transparent:

 Water-based, transparent, penetrating dye that behaves like traditional tannery stains 

 Brilliant Staining Effect:

 Enhances the natural beauty, depth, and character of the leather grain or nap rather than concealing it 

 Lively, rich color:

 Produces more vibrant and vivid results compared to most conventional liquid dyes 

 Superior lightfastness & fade resistance:

 Offers better UV stability and longer-lasting color than standard liquid dyes.

 Water-based & leather-safe:

 Compatible with Leather Doctor’s tannery science-based care system, ensuring no harm to the leather’s structure or pH balance when used as directed. 

 Flexible color shading:

 Can be diluted with distilled water or Leather Hydrator 3.3 for lighter, custom color shades 

 Application Methods

 Applied using lint-free towels, foam brushes, varnishing brushes, or airbrush (recommended) for best control and evenness without over-wetting.

 Leather Fatliquor 5.0 by Leather Doctor® is a leather-safe pH 5.0 emulsion of fat, oil, and water designed to replenish the original fatliquor content of leather’s fibrous structure.

 It restores leather’s internal lubrication, flexibility, strength, and resilience—mimicking the essential fatliquoring stage in professional tanning and retanning processes.

 Fatliquor 5.0 Key Benefits:

 Lubricates and nourishes the leather structure

 Fatliquor 5.0 deposits fat and oil molecules that bond to the amphoteric protein fibers.
 These lubricate the fibrils, allowing them to slide over each other without stiffness, brittleness, or cracking.

 Reinforces tensile strength and elasticity

 Proper fatliquoring prevents fiber embrittlement and maintains leather’s natural strength and softness.

 Restores suppleness and prevents future damage

 Leather loses fatliquor over time due to aging, heat, sunlight, alkaline exposure, or cleaning.

 Replenishing it prevents shrinkage, stiffness, and cracks.

 Provides long-term structural protection

 Maintains leather’s dimensional stability and ability to flex without damage.

Tannery science basis:

 In the tannery, fatliquoring is one of the final and most critical stages after tanning and dyeing.
 It ensures that leather stays soft, strong, and flexible as it dries.
 The fats and oils form a molecular film around the protein fibers, acting as internal lubricants.

Leather Fatliquor 5.0 brings this same process to leather restoration.
 It ensures the leather is not just “looking good on the surface” but structurally rejuvenated from within.

 Leather Primer Adhesor 73 by Leather Doctor® is a compact resin primer designed to smooth, seal, and enhance adhesion before color coating.

 Adhesor 73 is formulated and designed to: 

 Smooth and seal leather surfaces.
 Enhance adhesion for color coating.
 Build uniform surfaces over rough or abraded areas.
 Assist in removing deteriorated finishes.
 Reactivate aniline dyestuff to some extent.

 Aniline Waxy Matte Coating Dye 21 by Leather Doctor is a next-generation transparent surface coating dye that provides excellent color coverage with a waxy matte.

 This vivid and bright dye coats the leather surface rather than penetrating it, offering enhanced color intensity and uniformity. It can be applied over existing bronzing-stained dye effects, such as Aniline 21, or over existing finishes to enrich and revitalize the leather’s appearance.

 Aniline Finish Topcoat Waxy Matte 21 by Leather Doctor® is a water-based sealing topcoat formulated with fine particle-size urethane waxy resins.

 Matte 21 provides a matte luster and a distinct waxy feel, perfectly suited to preserve and enhance waxed aniline leathers while maintaining their natural aesthetic and soft texture.

 How to Identify Leather Stains?

Stain identification is crucial for effective treatment and is based on six key factors:
Appearance, Odor, Color, Feel-of-Hand, Location, and Buildup or Absorption.

 Appearance

  • Observing how the stain looks can indicate whether it is a spill, rub-on, penetration, or surface deposit.
  • Some stains may cause dye or finish damage, revealing changes in the leather’s color or texture.

    Odor

  • Smelling the stain can help identify its source.
  • Common odors include:
    • Moldy (fungal growth)
    • Smoke (fire or cigarette exposure)
    • Putrid (decaying organic matter)
    • Ammonia (urine contamination)

    Color

  • Color provides a clue to the staining substance but can change over time due to oxidation.
  • The leather’s natural color may also influence how the stain appears.
    • Red stains: Could be from wine, blood, lipstick, nail polish, or beverages.
    • Blood stains: Can oxidize and shift from red to tan, then to black.

     Feel-of-Hand

  • Touching the stain helps determine its type:
    • Sticky: Likely from candy, beverages, or sugary substances.
    • Brittle and stiff: Could be nail polish, paint, or shellac.
    • Greasy smear: Often caused by lipstick, oils, or butter.

     Location

  • The stain’s location on the leather provides hints about its origin.
    • Headrests & armrests: Usually stained by body oil, sweat, and grease.
    • Seat cushions: Often show food or beverage spills.

   Buildup or Absorbed

  • Stains can be surface-level (built-up) or deeply absorbed into the leather.
    • Built-up stains (common on pigmented leather) include paint, food residue, and ink.
    • Absorbed stains (common on nubuck, aniline, and unfinished leather) include wine, tea, and coffee.
    • Combination stains: Some stains contain both absorbed and surface elements, such as lipstick, ink, and mustard.
    • Protein-based stains: Examples include blood, dairy, and egg-based spills.
    • Oil-based stains: Often come from grease, butter, and lotions.
    • Colloidal stains: May require specialized treatments.

    Additional Considerations 

  • Sweat stains can chemically alter leather, causing tackiness (when dry) or sliminess (when wet).
  • Dye stains may show up when wiping with a white towel—this indicates color crocking.
  • Fatliquor leaching (spew) appears as a milky film and causes leather to become stiff and prone to cracking.

By carefully identifying stains, you can apply the appropriate Leather Doctor® solutions to restore leather to its original beauty.
