Product Overview
Auto Perforated Leather Cleaner & Conditioner Kit AF3 by Leather Doctor is a preventive, routine, periodic, and restorative cleaning and conditioning system.
Perforation is created by machine punching small holes regularly in spaces, commonly found in leather car seats for seating comfort. Semi-Aniline perforated leather is aniline dyed through and has the surface coated with fine micro pigment. The perforated exposed suede naked cross-section shows aniline dyed and is more vulnerable to stiffness, creases, and cracks. The softness or suppleness derives from its fat liquor (fat and oil) content in the structure. Fat liquor fat and oil is VOC (volatile organic compound) and evaporates with aging or heat; leached out with water damage or an alkaline cleaning solution; when dry leather stiffs out, creases, and the perforated hole edges develop cracks. Fatliquor is the lifeblood of leather! Periodic replenishing perforated leather with fat liquor will ensure perpetual leather softness and strength.
Kit AF3 concentrates require 1178g or 1.3 quart distilled water to be mixed and added to 1.5 inches below the top of the 8oz bottles before use.
Instruction:
Prep 4.4 a leather-safe pH4.4 restorative cleaner, works on accumulated soiling, aged conditioners, chewing gum, silicone shine, sticky residue, and greasy soiling. The compound stain dye component will require Dye 7.9 for ballpoint ink, blue jean dye, crayons, leather belts, plastic ink print, newsprint, stamp pad ink, etc.
1.1: Prep 4.4 is applied and works with a horsehair brush on heavily soiled areas and stains.
1.2: Prep 4.4 suspended soiling is towel extracted before dries until it shows clean and continues with general cleaning.
Cleaner 3.8 is a leather-safe pH3.8 mild cleaner that is particularly effective in emulsifying and suspending oily soils without common side effects. It works over after Prep 4.4 and extends the entire section without leaving a dry edge. Cleaner 3.8 holistic cleaning and rinsing sequence with Rinse 3.0 returns residue free to its pH chemistry integrity.
2.1: Cleaner 3.8 concentrate 1: 64 is mixed with 224g distilled water or 1.5 inches from the top of the 8oz bottle before use.
2.2: Cleaner 3.8 is applied and brushed with a horsehair Brush 1.
2.3: Cleaner 3.8 suspended soiling is extracted with a dry absorbent towel until it shows clean and proceed with rinsing.
Rinse 3.0 is a pH3.0 rinse for removing suspended soil and strengthening the pH chemistry integrity of leather. It removes suspended soiling by towel extraction while neutralizing harmful alkaline residues and charging the leather ionic positive (+ve) to increase the attraction between the ionic negative (-ve) tanning agent, dyestuff, and fat liquor from tackiness, bleeding, and stiffness.
3.1: Rinse 3.0 concentrate 1: 80 is mixed with 224g distilled water or 1.5 inches from the top of the 8oz bottle before use.
3.2: Rinse 3.0 after Cleaner or identify, inspect, test, and dry soil removal before application.
3.3: Rinse 3.0 is applied, and brushed with a horsehair Brush 1.
3.4: Rinse 3.0 suspended soiling is extracted with a dry, absorbent towel, and proceed with hydrating.
Hydrator 3.3 is a pH3.3 hydrating conditioner to relax and stretch out leather stiffness, creases, and wrinkles before fat liquoring. It facilitates colloidal water movement, reactivating the dormant dyestuff to resurface and reducing the leather surface inter-facial tension for an even appearance.
4.1: Hydrator 3.3 concentrate 1: 25 is mixed with 218g distilled water or 1.5 inches from the top of the 8oz bottle before use.
4.2: Hydrator 3.3 is applied and brushed with a horsehair Brush 1 with a deep even saturating appearance, massaged, and stretched to dimension.
4.3: Hydrator 3.3, wicked soiling is extracted with a dry, absorbent towel, and proceed with fatliquoring.
Fatliquor 5.0 is a pH5.0 micro-emulsion of fat, oil, and water for conditioning leather to its original softness and strength. In application, the water-encased fat and oil molecules break free when the attraction between the leather protein fibers takes place. The excess free water wicks out leaving a breathing space behind for Nubuck's natural transpiration.
5.1: Fatliquor 5.0 concentrate 1: 5 is mixed with 189g distilled water or 1.5 inches from the top of the 8oz bottle before use.
5.2: Fatliquor 5.0 is applied and redistributed with a brush or pad for even saturation and leaves to dry naturally.
5.3: Fatliquor 5.0 is repeated each cycle water contents evaporate leaving behind the fat and oil content until it absorbs no more.
5.4: Fatliquored leather fullness is allowed natural drying for extra softness.
5.5: Fatliquored desired suppleness is further staked, massaged, and flexed accordingly with a little wet back with Hydrator 3.3 until dry.
Conditioner W is a nonstick, rub-resistant, non-film-forming conditioner that imparts a soft waxy feel to shield the detrimental effects of sticky soiling. Its breathable barrier increases resistance to wet and dry rubs, thus reducing stretch, scuff, and abrasion.
6.1: Conditioner W concentrate 1:19 is mixed with 217g distilled water or 1.5 inches from the top of the 8oz bottle before use.
6.2: Conditioner W is applied, spread with a brush or a folded towel, is left to dry, and ready to use.
7.1: Protector B concentrate is to be mixed with 215g distilled water 1: 19 or 1.5 inches from the top of the 8oz bottle before use.
7.2: Protector B is applied and spread by brushing or padding and is ready to use when dry.

A: How to Identify Leather Stains?
Leather Stains are identified by: Appearance, Odor, Color, Feel-of-Hand, Location, and Buildup or Absorbed!
1: Appearance
1.1: Stain identification by appearance will show whether it is characteristic of a spill, rub-on, penetrated or deposited.
1.2: Stain may also reveal dye or finish damages caused by the stain.
2: Odor
2.1: Odor-by-smell identification can be helpful in positive stain identification.
2.2: Odors such as moldy, smoke, putrid, or ammonia from urine are some common stains identified by smell.
3: Color
3.1: Color stain identification will also give a clue to the staining stuff.
3.2: Color stains from beverages, nail polish, lipstick, blood, or others could all appear red.
3.3: Color identification may not be right with time and oxidization, a red bloodstain may turn from tan to black.
3.4: Color of the leather may mesmerize or alter the appearance of the stain.
4: Feel of Hand
4.1: Feel-of-hand stain identification may help determine the stain types.
4.2: Feel sticky and appear red as a candy, beverage, or sugar substance.
4.3: Feel brittle and stiff could be a nail polish, shellac, or paint stain.
4.4: Feel the smear by hand could be a grease-base stain as lipstick.
5: Location
5.1: Location may give a clue as to the makeup of the staining substance in visual inspection and identification.
5.2: Location on the headrest and armrest of furniture is common with dark stains from body oil, grease, and sweat.
6: Buildup or Absorbed
6.1: Stains may take several appearances.
6.2: Stains accumulate mostly on top of non-absorbent pigmented leathers.
6.3: Stains are mostly absorbed on unfinished, Vachetta, aniline, and nubuck leathers.
6.4: Stains can also be combined, absorbed, and built up.
6.5: Stains absorbed indicate it was a liquid before it penetrated the leather.
6.6: Stains that are liquid stain may have chemically changed, destabilized the leather chemistry integrity, and altered its appearance.
6.7: Example of sweat stains often react with absorbent leathers and denature them.
6.8: Examples of stains affecting the tanning agent that manifest as tackiness when dry and sliminess when wet are detected by the feel of the hand.
6.9: Examples of stains affecting the dyestuff occur when color appears during wet wiping with a white absorbent towel.
6.10: Examples of stains affecting the fat liquored fat and oil leaching out as a milky film known as spew, the leather becomes stiff, loses its tensile strength, and cracks when stressed.
6.11: In any event, the leather may show a marked color change in that area after spotting, and possibly after cleaning.
6.12: Examples of built-up stains include paint and some foodstuff, etc.
6.13: Examples of absorbed stains include beverages, wine, tea, coffee, etc.
6.14: Examples of combination stains include lipstick, ink, mustard, etc.
6.15: Most absorbed stains will have part of their staining stuff absorbed into the leather and part accumulated on its surface.
6.16: A stain may also be a substance that has wet solvent-soluble and dry solvent-soluble components combined.
6.17: Examples of a compound stain would be gravy which contains grease, flour (from a plant), and milk (from an animal).
6.18: Examples of paint-type stains are readily detected because of their stiff nature and generally bright colors and they seem to be sitting on top of the leather.
6.19: When identifying stains always try to determine whether they are of a protein, cellulose, oil-based, or a colloidal make-up in nature.
6.20: Three common types of soiling or stain are solvent-soluble, water-soluble, and insoluble.
6.21: Stains are often of a combination in nature, and in most instances, there will be no information regarding the stain especially if they are bought used.
B: What is a Systematic Cycle of Care?
A systematic cycle of care includes preventive, routine, periodic, and restorative levels of care to bring leather suppleness, and appearance at all times high.
C: What is a Preventive Care System?
A preventive care system is the application of non-stick, rub-resistant protection to increase the leather's resistance to wet and dry rubs, thus reducing stretch, scuff, and abrasion with Protector B and Protector W.
