Pigmented Leather Cleaner & Conditioner Kit P3

Pigmented Leather Cleaner & Conditioner Kit P3 by Leather Doctor® prep, clean, rinse, hydrate, soften, and condition, helps maintain appearance and prolong lifespan. 

Pigmented leather is often known as painted, protected, or finished leather due to its common uniform opaque pastel color. This effect is achieved with opaque pigments, ensuring consistent color across the surface. A pigmented leather finish system consists of an adhesion coating (Adhesor 73), color coating (Pigment 54), and top coating (Topcoat 54), which vary in type and quality depending on the leather grade. These coatings can range from fine to heavy applications to suit different leather types. The overall quality of pigmented leather is influenced by the leather crust from which it is derived, such as full-grain, top-grain, or corrected-grain leather. A key characteristic of pigmented leather is its hiding power, which conceals imperfections that would otherwise be visible.

Although pigmented leather is highly stain-resistant, it remains susceptible to ballpoint ink marks and dye transfer. Over time, dark soiling accumulates in grooves, creases, lines, and wrinkles, often giving the appearance of cracks. If neglected, micro-crazing can progress into serious cracking as fat liquor diminishes due to evaporation. In addition, fat liquor loss from alkaline exposure can lead to stiffening and cracking. Overstretching weakens the leather’s structure, causing looseness in high-contact areas, while prolonged sweat exposure can result in a sticky, tacky surface.

Accumulated soiling is recommended to be removed effectively by Prep 7.7, Cleaner 3.8, and Rinse 3.0 systems. If the leather has become overstretched, its structure can be restored using the Hydrator 3.3 and Fatliquor 5.0 system, best applied from the reverse suede side for optimal results. Impregnator 26 as an option reinforces and tightens the leather’s fibrous structure for a more permanent tightening and strengthening solution. Routine sanitizing with Sanitizer 3.9 helps reduce the risk of alcohol-related stickiness and potential damage to leather finishes. Conditioning the leather surface with Protector B helps reduce friction rubs, reduce sticky soiling, keeping the leather smarter, and looking good longer.

Other common pigmented leather concerns fall into five key categories: Soil, Stain, Odor, Structure, and Finish, which are outlined in detail in the Leather Problem-Solving Matrix for reference.

This Kit P3 concentrates require 1068g (1.1 quarts) of distilled water for dilution before use. All products are also available individually for tailored leather care solutions.

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.

1 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.

2 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)

3 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.

4 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.

5 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.

6 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.

7 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.

How to Use this Pigmented Leather Problem-Solving Matrix?

This matrix categorizes common issues with pigmented leather into five groups: Soil, Stain, Odor, Finish, and Structure (listed in the left column). Corresponding recommended products are displayed across the top row. Each number within the matrix indicates the steps required to address the problem holistically.

For example:
If a leather issue involves an unknown compound that combines soil, stain, and odor, follow the sequence across the matrix, combining necessary steps from each category. The process should always conclude when the leather finishes become absorbent from micro-crazing, abrasion, scratches, and stitching holes.

• Hydrator 3.3 to rehydrate and relax the leather.
• Fatliquor 5.0 to replenish lost fats and oils, restoring suppleness.
• Protector B conditioning the leather for ongoing durability.

4. What is Leather Restorative Care?

1 What is Leather Preventive Care?

Leather Preventive Care is an essential part of maintaining leather's appearance and durability over time. The goal of preventive care is to shield leather from soiling, wear, and aging, while maintaining its luxurious feel and natural look. Leather preventive care starts and ends with Step 6 Conditioning:

2 What is Leather Routine Care?

Leather routine care is essential to maintaining the beauty and durability of leather over time. This process includes dust cleaning, spot treatment, pH balancing to neutralize sweat stains, and applying a protective conditioner to enhance resistance against soiling and wear. Leather routine care begins with Step 2 Cleaning, Step 3 Rinsing and ends with Step 6 Conditioning.

3 What is Leather Periodic Care?

Leather periodic care is recommended before soiling causes damage to the finishing. This keeps leather consistently clean and healthy at all times. Body contact areas would require more frequent attention than the unused areas. The leather headrest,  handrest, and footrest get the most out of body oil and sweat contacts. Hydrating and Fatliquoring are recommended to surface absorbent areas. Leather periodic care begins with Step 2 Cleaning, Step 3 Cleaning, Step 4 Hydrating, Step 5 Fatliquoring and ends with Step 6 Conditioning. 

4 What is Leather Restorative Care?

Leather restorative care is the ultimate restorative or salvage care system that removes accumulated soiling including aged conditioners. Accumulated soiling that fills creases is often mistaken for cracks. Prep 7.7 performs restorative cleaning. It works by chemical reaction to emulsify soiling through its penetrating, lubricating, and suspending power. Horsehair detailing Brush 1 is recommended to be worked into heavily soiled areas sufficiently to avoid excessive agitation that might damage already weakened finishes, especially on heavily used areas. Hydrating and Fatliquoring are recommended to surface absorbent areas. Leather restorative care begins with Step 1 Prepping, Step 2 Cleaning, Step 3 Cleaning, Step 4 Hydrating, Step 5 Fatliquoring and ends with Step 6 Conditioning.
