Product Overview
Leather Getting Sticky Restoration Kit L7 by Leather Doctor® restores sticky and slimy leather caused by absorbing sweat and harmful cleaners and conditioners.
-
Incompatible Conditioners:
Residue from non-leather-safe oily or waxy conditioners accumulates, turning sticky.
Recommended: Aniline Leather Cleaner & Conditioner Kit A3. -
Deteriorating Topcoat Finishes:
Bicast, pigmented, or simulated leather may lose their topcoat, becoming tacky.
Recommended: Bicast Leather Sticky Topcoat Refinishing Kit B7. -
Sweat and Alkaline Damage:
Leather exposed to aging sweat or alkaline cleaners (especially on pH-sensitive leathers like aniline, vachetta, or nubuck) denatures into sticky rawhide.
- Sweat shifts pH, leaching tanning agents.
- Leather is amphoteric and reacts negatively to pH imbalance (ideal pH: 3–5).
Most sticky conditions are worsened by alkaline cleaners, disrupting leather's ionic balance.

Kit L7 Includes:
pH 1.5 is a low pH (1.5) ionic, negatively charged (-ve) water-based restorative cleaner specially designed to neutralize and balance side effects on leather and suede caused by alkaline overexposure—such as bleeding, discoloration, or stickiness.
Leather has a natural pH range of 3 to 5. When exposed to products with high pH (alkaline)—like saddle soap, baking soda, dish detergent, above pH 7, or harsh commercial cleaners—the leather structure becomes denatured, leading to long-term damage. pH 1.5 reintroduces acidity (extra H⁺ ions) to protonate the protein fibers, helping to restore the leather’s integrity and bring it back to its healthy, pH-balanced state.
pH 1.5 functions by restoring the leather’s pH balance through its low pH value of 1.5. This acidic solution increases the ionic positive (+ve) attraction of the amphoteric leather protein fibers, allowing them to form hydrogen bonds with negatively charged (-ve) leather constituents.
This action helps to:
pH 1.5 is part of a holistic Leather-Safe™ restoration system designed to correct leather denaturing caused by alkaline exposure (e.g., sticky, slimy, or discoloration).
It prevents leather from denaturing, which can lead to bleeding, streaking, tackiness, and structural weakness due to alkaline overexposure.
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.
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.
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.

3-Step Restoration Process:
Step 1: Decontaminate and pH-Balance
Products: pH 1.5 + Acidifier 2.0
- Remove dry soil.
- Apply pH 1.5, agitate with Brush 1, and extract with a clean towel.
- Apply Acidifier 2.0, brush, and extract again until the towel shows clean.
- Repeat Acidifier 2.0 application to saturate the leather, allow to dwell, then extract again.
- Continue until stickiness significantly reduces.
- While still damp, proceed to Step 2.
Step 2: Hydrate and Soften
Products: Hydrator 3.3 + Fatliquor 5.0
- Apply Hydrator 3.3, brush in, and extract. Repeat as needed to flush out contamination and redistribute displaced tanning agents.
- While leather is damp, apply Fatliquor 5.0 in multiple light applications until saturated.
- Allow water content to evaporate naturally; only fat and oil remain in the leather.
- Remove surface residue with Hydrator 3.3 and let dry.
- Before fully dry, flex or massage the leather for softness.
Step 3: Impart Non-Stick Protection
Product: Protector B
- When dry, apply Protector B evenly with a foam brush or towel.
- Leather is now ready for use.
