Leather Degreaser, Rinse, Hydrator, Softener & Protector Kit D3 by Leather Doctor® is a complete professional leather-safe degreasing and conditioning system designed to remove body oils, sweat, and grease while restoring softness and natural strength.
- Just like shampooing hair, proper leather degreasing requires rinsing to flush out suspended soiling. Kit D3 follows this tannery-aligned system:
Degrease → Rinse → Hydrate → Soften (Fatliquor) → Protect.
- Unlike solvent-based degreasers that dissolve essential fatliquor and leave leather stiff and dry, Leather Doctor® Degreaser 2.2 uses a low pH 2.2 water-based formula that preserves leather chemistry—maintaining the ionic attraction between fibers, tanning agents, dyes, and oils.
The result?
- Clean, soft, and supple leather that stays strong, flexible, and beautiful.

Leather Degreaser 2.2 by Leather Doctor® is a professional, water-based solution that removes body oils, sweat, and grease from leather surfaces. Like shampooing hair, degreasing requires rinsing to carry away suspended soils—leaving leather clean without stripping its essential oils.
- Unlike solvent-based degreasers that dissolve the tannery-applied fatliquor (the essential blend of oils and fats), causing leather to become stiff, dry, and brittle, Degreaser 2.2 works with tannery science.
- Its low pH 2.2 formula maintains the ionic attraction between leather fibers, tanning agents, dyes, and fatliquor.
- This ensures the leather remains supple, strong, and ready to accept hydration and replenishment, restoring its original softness and durability.
Rinse 3.0 Key Features & Benefits:
- Removes Suspended Soil – Lifts and extracts emulsified soiling for a clean, residue-free finish.
- Neutralizes Alkaline Residue – Restores pH balance to prevent damage from alkaline overexposure.
- Prevents Tackiness & Dye Bleeding – Stabilizes the leather structure, reducing unwanted texture changes.
- Enhances Leather’s Ionic Charge – Recharges the leather with a positive (+ve) charge, improving its ability to bond with negatively (-ve) charged tanning agents, dyestuff, and fatliquor.
- Preserves Suppleness & Durability – Helps maintain the leather’s softness, preventing stiffness and cracking.
- This essential finishing rinse ensures leather remains clean, soft, and structurally sound after the cleaning process.
Recommended Usage:
- Apply Rinse 3.0 – Gently work into leather using a towel to lift and extract soil.
- Blot Away Residue – Use a clean, absorbent cloth to remove excess moisture.
Allow to Dry Naturally – Ensure proper drying to maintain leather integrity.
- Follow while still damp with Hydrator 3.3 & Fatliquor 5.0 (if needed) – For deep relaxation and softening.
- This essential finishing rinse ensures leather remains clean, soft, and structurally sound after the cleaning process.
Hydrator 3.3 Key Benefits:
- Restores Leather Softness & Flexibility – Relaxes stiff fibers and prevents brittleness.
- Smooths Out Creases & Wrinkles – Prepares leather for optimal softening.
- Reactivates Dormant Dyestuff – Helps resurface color for a more even appearance.
- Facilitating Colloidal Water Movement - Redistributing and balancing leather constituents.
- Prepares for Fatliquoring – Enhances absorption of essential fats and oils.
- Residue-Free & Non-Sticky – Ensures a clean, breathable finish.
How Hydrator 3.3 Works:
- Hydrator 3.3 penetrates deeply into the leather, reducing surface tension and facilitating colloidal movement to redistribute and balance the leather constituents, reactivate dyestuff, and even out color inconsistencies.
- It plumps the leather structure, making it more receptive to fatliquoring with Fatliquor 5.0, which restores essential oils for long-term suppleness and durability.
Fatliquor 5.0 Key Benefits:
- Replenishes Essential Fats & Oils - Prevents leather from drying, stiffening, or cracking
- Enhances Leather’s Suppleness & Elasticity - Maintains a soft, luxurious feel
- Strengthens Leather Fibers - Improves tensile strength and durability
- Creates a Breathable Structure - Ensures leather remains pliable without feeling greasy
- Prevents Brittleness & Fiber Breakage - Essential for long-term leather preservation
How Fatliquor 5.0 Works:
- When applied, the water-encased fat and oil molecules penetrate deep into the leather fibers.
- As the water gradually evaporates, the fat and oil molecules hydrogen bond with the fibers, creating a breathable, flexible structure that enhances leather’s resilience and longevity.
Proper fatliquoring ensures that leather retains its tensile strength, resists breakage, and maintains its natural softness, preventing premature aging and deterioration.
