 Acidifier 2.0 Key Benefits:

 Neutralizes alkaline contamination from cleaners, and aging sweat.
 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 leather to prepare 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 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, appearance 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.
 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: 

 Aniline Wax Pull-up.

 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:

 Purpose

Aniline Staining Dye 21 is formulated for:

 Re-dyeing leather fading
 Creating uniform or shaded effects while allowing natural markings and grain to remain visible
 Maintains the leather natural breathability.

 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 formulated 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.

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 Conditioner Wax Pull-Up 8.6 by Leather Doctor® is a rejuvenator for restoring the diminishing aniline wax effect lost through usage, aging, or cleaning.

It is highly recommended that the primary leather softening process of hydration and fatliquoring be completed to satisfaction before applying the secondary wax pull-up effect.

 The Importance of Hydration & Fatliquoring Before Applying Wax Pull-Up 8.6: 

Before restoring the pull-up effect, it is highly recommended to complete the primary softening process through hydration and fatliquoring. Here's why:

  Hydration – Relax, Revive & Rejuvenate

Over time, leather loses moisture due to aging, environmental exposure, and cleaning. Dry leather fibers become stiff and prone to cracking. Hydration helps:

 Relax stiff fibers and correct shrinkage
 Open up the leather structure for better fat and oil absorption
 Reduce dryness-induced creases and stiffness

  Fatliquoring – Restoring Softness & Strength

Once hydrated, leather requires fatliquoring, which replenishes the natural fats and oil that provide:

 Softness and flexibility
 Internal lubrication to prevent stiffness and cracking
 Resistance against premature wear and aging

  Wax Pull-Up Effect – Finishing Touch for Beauty & Function

Only after leather is fully softened should Wax 8.6 be applied. This ensures:

 A revived wax pull-up effect for a rich, dynamic look
 Enhanced suppleness without overloading stiff leather
 Long-lasting protection and beauty

By following this two-step restoration process, you maximize the longevity and luxurious feel of aniline wax pull-up leather.

 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 Gloss Coating Dye 76 by Leather Doctor® is a next-generation water-based transparent surface coating dye formulated for vivid, brilliant color coverage on leather.

 Unlike traditional penetrating dyes, Aniline 76 forms a transparent surface film, enhancing color intensity, uniformity, and gloss while preserving the natural beauty of the leather grain.

 Aniline 76 Key Features:

 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.
