Aniline Leather Cleaner & Conditioner Kit A3

Aniline Leather Cleaner & Conditioner Kit A3 by Leather Doctor spots, cleans, rinses, hydrates, softens, and conditions in preventive, routine, periodic, and restorative leather care. 

Aniline leather color is derived from a transparent dyestuff dyed through to the reverse suede side. Most often the surface is further dye coated to even out appearance and sealed with a urethane clear gloss topcoat to bring the beauty of the grain show through. Microcrazing develops sooner making the leather more comfortable in transpiration and increasing absorbency. Take good care of aniline leather, even unused, it will still dry up and softness turns to stiffness especially when exposed to heat or sunlight, and the color fades. Color is refreshed periodically by hydrating the dormant dyestuff within the leather structure to resurface. Unnatural creases, wrinkles, or curls need hydration to relax and stretch before replenishing the diminishing fat and oil. Fatliquor keeps the leather supple, and soft with strength, making it less absorbent, as aniline leather is both hydrophilic and oleophilic, easily liquid stain. A cycle of care matching the severity of the soiling maintains its highest level of appearance, softness, strength, and feel of touch at all times.

Kit A3 concentrates require 1070g or 1.2 quart distilled water to be mixed and added to 1.5 inches below the top of the 8oz bottles before use.

1. What is a Preventive Care System for Aniline Leather?

A preventive care system for aniline leather is the initial surface conditioner Protector B applied before putting it to use to impart the leather with a buttery feel that enhances the leather luxuriously to the sense of touch; a nonstick surface that shields the leather from sticky soiling thus prolonging a high level of appearance; a rub-resistant ability reduces friction noises that translate into less friction wear; and the optional leather scent diffuses a classic leather scent that boosts the sensuous leather more appealing to the leather lover.

2. What is a Routine Care System for Aniline Leather?

A routine care system for aniline leather includes procedures such as dusting, cleaning, and attending to spots and stains as required especially the pH balancing of sweat stains from shifting alkaline, thus preventing the leather from tackiness. A routine nonstick rub-resistant conditioning after neutralizing rinse helps keep leather attractive and healthy while preventing premature wear.

3. What is a Periodic Care System for Aniline Leather?

A periodic care system for aniline leather 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; while the leather headrest, hand rest, handles, etc gets the most of body oil and sweat.

4. What is a Restorative Care System for Aniline Leather?

A restorative care system for aniline leather is the ultimate restorative or salvage care system that removes accumulated soiling including aged conditioners, and accumulated soiling that fills creases is often mistaken for cracks.

5. 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.
