    Default Sequence of products

    Hi Roger,

    I received my kit today. Thank you very much.

    I would just like to confirm the sequence of the products in use.
    Ink 7.7 (Not needed right now)
    Super Cleaner 4.0
    Cleaner 3.8
    Rinse 3.0
    Fatliquor 5.0
    LeatherScentB

    What dwell-time should I allow for the cleaners and the Fatliquor? And also how warm does the Fatliquor need to be? I was going to sit the bottle in a bowl of warm water for a while...?

    If you have tips or tricks before I set to work this weekend, I would greatly appreciate them!

    Thanks again.
    Brian

    Dear Brian and Viewers,

    Necessities “dwell time” 5 to 10 minutes for superCleaner4.0™ and longer for ink7.7™spotter (depending on age and types of spots and stains like: ink, silicone, paint, lipstick, crayon, nail-polish, etc.).

    Fatliquor5.0™ at room temperature approximates 20 degrees Celsius or 68 degrees Fahrenheit is sufficient (not frozen cold, especially during winter condition).

    Generally a conventional tannery fatliquoring process is done in rotating drums where the temperature for vegetable-tanned leathers is about 45 degrees Celsius or 113 degrees Fahrenheit and about 63 degrees Celsius or 145 degrees Fahrenheit for chrome leathers.

    These temperatures are necessary to keep the fatliquor in a milky emulsion for effective penetration into the leather fibrilliary structure.

    Comparatively, fatliquor5.0™ is the “cold non-immersion spray version” of the “tannery drum warm immersion system”.

    It does not require heat to create this milky emulsion similar to fresh milk unlike the tannery warm immersion system.

    It is useless to spray on non-absorbent leathers especially auto/car seat if they are new without cracks or perforation holes for penetration.

    The most effective method is to apply from the suede side if possible.

    All leathers have to be fatliquored for greater softness, flexibility and strength.

    These original fatliquor will diminish through cleaning and ageing and need replenishing to maintain original softness and strength.

    Creases and coarse breaks are signs of diminishing fatliquor, cracks are obviously too late where the leather fibrils breaks like natural dried ropes or thread.

    Sun dried cardboard stiffness have chances of softening by rehydration with cleaner3.8™ and rinse3.0™ before spray fatliquoring.

    The important point to take note is that the natural oil droplets encased by the water should remain as a milky emulsion until they penetrate the leather.

    It should not separate out as large drops or as layer of oil, which could not penetrate the leather fiber and would only give a greasy useless surface layer with no benefit to the leather.

    Ideally, the most effective method of “spray fatliquoring” is to apply to damp leathers after cleaner3.8™ and rinse3.0™.

    Quick absorption by the leather when it is applied to dry absorbent light colored leathers often result in dark-colored greasy patches.

    Furthermore, the end result is not as soft, flexible or full compared to when it is applied to the damp plump-up leather.

    Therefore when applied to damp leather into the intimate fibrilliary structure will have better pronounced increase in softness, flexibility, fullness and strength.


    superCleaner4.0™ is leather pH 4.0 balanced aqueous mild acidic super preconditioner.

    Developed as a preconditioner for restoration cleaning or as a first steps preconditioner prior to color refinishing.

    Designed to works safely in harmony with leather, suede and nubuck tanning agent, dyestuff, fatliquor and finishes.

    Formulated to acts like a superior solvent type cleaner without the solvent negative effect to the leather finishes.

    Allows sufficient "dwell time" to penetrate deep into the leather for grease based soil emulsification, deflocculation and suspension to occur.

    Effectiveness includes newsprint and blue jean color transfer from light colored leather, nubuck and suede.

    Heavy spottings or silicone strippings especially auto/car use Ink7.7™spotter for non-absorbent leathers and superSpotter4.6™ safer on absorbent leathers.

    Preparation:

    Identify, inspect, dry soil removal & safety setup before application.

    Instruction:

    Shake well, spray evenly and agitate with leatherBrush1™, nubuckBrush2™ or suedeBrush3™ accordingly.

    Let dwell 5 to 10 minutes before proceeding with cleaner3.8™ and rinse3.0™ for a residue free clean.


    cleaner3.8™ is leather pH 3.8 balanced aqueous mild acidic relaxer-cum-cleaner.

    Designed to works safely in harmony with its tanning agent, dyestuff, fatliquor and finishes.

    Developed for a safe and effective general cleaning for all types of leather (finished and unfinished) and suede (nubuck and suede).

    Cleaning includes all synthetic and natural fabric except rayon and silk.

    Formulated for effective soil penetration, lubrication and suspension through chemical reaction without the negative effect commonly associated with soap, alkaline and solvent ingredient cleaners.

    Preparation:

    Identify, inspect, bleeding test, wet rub test, dry soil removal & safety setup before cleaning.

    Instruction:

    Shake well, spray evenly over the entire surface a cushion, section or panel at a time.

    Agitate with leatherBrush1™, nubuckBrush2™ or suedeBrush3™ accordingly.

    Then extract suspended soil with a dry absorbent towel.

    Normal color transfer onto towel is acceptable from over dyed aniline, nubuck or suede.

    Proceed with rinse3.0™ for a residue free clean.


    rinse3.0™ is leather pH 3.0 balanced mild acidifier-cum-rinse.

    Designed to works safely in harmony with leather tanning agent, dyestuff, fatliquor and finishes.

    Developed to safely and effectively neutralize and remove harmful alkaline soil and perspiration residue from all types of leather (finished & unfinished) and suede (nubuck & suede).

    Rinsing includes all synthetic and natural fabric except rayon and silk.

    Formulated to further enhance, stabilize and strengthen the leather chemistry integrity.

    Enhance the cationic charge to the leather intimate fibrillary structure below the iso-electric point.

    Plumps and acidifies the leather structure for anionic fatliquor5.0™ to have a rapid ionic fixative bond.

    Instruction:

    Spray evenly damp, optional lightly agitate with leatherBrush1™, nubuckBrush2™, or suedeBrush3™ accordingly.

    Then extract clean with a dry absorbent towel until towel shows free of soil.

    Rotating towel frequently as its surfaces become soil saturated.

    Repeat soil suspension as necessary or until towel shows free of soil.

    Proceed with fatliquor5.0™ while it is still damp.


    fatliquor5.0™ is the non-immersion cold spray version of the tannery immersion warm drum fatliquoring system.

    Developed to replenish original fatliquor diminishes through cleaning and ageing.

    An anionic charged formulation for superior polarity bonding with the cationic charged leather fibrils.

    Designed with a leather pH balanced value of 5.0 for superior penetrations, effective softening qualities and increasing the leather rip resistance tensile strength.

    Fatliquor is the lifeblood of leather.

    On application white milky microemulsion fatliquor penetrate deep into the leather as microscopic droplets.

    Once impregnated onto the leather fibrils and exhausted, the excess water evaporates leaving no greasy residue on the leather surface.

    These droplets bind to the leather fibrils and keep it separated from collapsing.

    This is unlike non-drying oil which stays on the leather surface that cannot penetrate the leather or stuffing oil that bleeds resulting in a mere greasy surface layer with no real physical benefit to the leather.

    Frequent fatliquoring seasons some lighter colored suede, nubuck and especially equestrian leather.

    Fatliquoring plumps up the leather with fullness and maintain its three dimensional size as well as providing lubrication to the leather fibrils.

    It relaxes coarse breaks, provides drapes, suppleness and prevents cracking.

    It helps keep the leather at its optimum physical performance and prevents premature ageing.

    Note:

    For direct dry application, dilute with distilled water 1:1-10 & test for darkening effect on light colored leather & suede after complete dry prior to actual application.

    It is most ideal to apply direct on damp leather after cleaner3.8™ and rinse3.0™ for better resultant appearance and softness.

    Instruction:

    Ensure it is milky like fresh milk otherwise warm up (room temperature) and shake well.

    Spray on cleaned damp surface evenly and massage (semi-absorbent) to allow even absorption into the thickness of the leather.

    For non-absorbent leathers, the fastest access is by the suede side.

    Light stretching while soaking through will improve those unwanted creases & coarse break for light fashion garment and gloves

    Natural slow drying preferred for extra softness.

    When dry, staking, milling, massaging, flexing or stretching seam to seam will get the leather as soft as you wish.


    leatherScent’B™ is a sensuous conditioner developed to enhance a soft natural buttery feel on all smooth pigmented leather.

    Impart an unforgettable classic leather scent.

    Provide a non-stick surface essentially to shield the detrimental effects of sticky soiling.

    Increase resistance to wet and dry rubs.

    Promote abrasion and scuff resistance.

    Reduce squeak when leather rubs against leather during movement.

    Instruction:

    Shake well.

    Mist spray on cleaned surface and spread evenly with a foam brush.

    Alternatively spray and wipe-clean with white dry absorbent towel to maintain leather as you like it.


    You should also have some fun time when you experiment with them.

    Hear from you soon as you experience the Leather Doctor® System.

    Thanks Roger. I have heard of people warming the leather to make conditioning easy. Is there any benefit to this that you know of ? Or is it that room temperature is better than cold leather...?

    Thank you

    Default Fatliquor5.0™ and Conditioners

    Heat in relation with fatliquor5.0™ and Leather Conditioners

    To soften leather fatliquor5.0™ (milky emulsion similar to fresh milk), tanning oils (pure) or leather conditioners must be able to penetrate the leather surface, so that the individual internal protein fibrils are uniformly coated or ionionic polarity bonded.

    Charged anionic fatliquor5.0™ with a negative head and a positive tail ion will attract an ionic charged bond with the protein cationic fibrils further enhanced by rinse3.0™.

    Tanning oil, fat or wax that has no charge are used for other purpose other than primarily for softening and strengthening leather.

    These non-charged “conditioners” may be just “stuffing conditioners” it just fill up the inter-fibrilliary spaces that suffocates the leather making it less permeable, so less comfort for outer weather wear purposes.

    It does serve it purpose as an effective water proofing, that is wax and oil for outdoor sports and games.

    Refined stuffing oil and wax are available as oilEffect63™ and waxEffect95™, both these are charged emulsion too!

    These effect oil and wax are designed for internal lighter usage for example in fashion garments and home furnishings.

    Leather conditioners that migrates or stuffs into the leather with no polarity bond will also migrate out naturally (squeeze in = squeeze out).

    Fatliquor5.0™ penetrates the leather fast by water medium, when the leather is damp without over saturating the inter-fibrilliary spaces.

    It does not require heat to do this job of penetrating and spreading the encased oil throughout the internal leather intimate fibrilliary structure for softness and strength.

    Generally, the more oil the softer and stretchier the leather becomes; but excessive amount of stuffing oil may give an undesirable, greasy feel or may interfere with color refinishing.

    Generally heat does play a part in the leather softening process or conditioning.

    Spray fatliquoring or hand oiling between 5 to 55 degrees Celsius is reasonable.

    It is reasonable to do conditioning between 5 to 35 degrees C, as the temperature goes to 55 C it becomes not practical unless in immersion drums in a tannery.

    The lower the temperature that fatliquor or tanning oil penetrates the leather, the better the product is.

    You save on time and convenience.

    Do you need to create a special sweat room or put your furnishing into a sauna to sweat it out immediately after application?

    When using raw conditioning oils the need of heat is greatly appreciates as an interface medium.

    The higher the heat the lower the interfacial tension between the leather surface and the oil molecules.

    The leather dimensional surfaces expands and the oil molecule becomes more volatile thus the oils migrate to a drier surface and stuff the void in between the interfrilliary spaces and coats the fibril as well.

    If pure conditioning oils is used so that it will wick up other foreign unwanted substances; it shows that the same oil migrated out with no bonding with the protein cationic fibrils or has it went in the first place?

    Comparatively, fatliquor5.0™ microscopic tanning oil are encased by water a true micro emulsion similar to fresh milk.

    Once these microscopic oil droplets penetrate and bond with the protein fibrils it breaks up and the water outer phase evaporates and wicks out the unwanted foreign substances with no greasy messy cloudy surfaces.

    For absorbent leather surfaces, there is no need to further cleaning these sticky messes as compare with other tanning oils.

    Using heat for better migration of conditioning oil into the leather surface serves its purpose.

    When temperatures cool down, the oil molecule contracts bigger and the leather surface tension increases; thus it’s a self locking device for the oils to stay in.

    So good as the temperature remains cooler that when the oils migrate in.

    Once the temperature rises to this critical optimum temperature where the “gates open and the oil molecule becomes volatile” it will reverse the action and migrate out, cause there are no polarity bonding.

    This phenomenal is known as “leather spew or spue” and to be remedied with either spew4.8™ or spew9.6™.

    A direct comparison is suggested to conclude your own “Conditioning” evaluation.

    The what?

    The How?

    The Which?

    And the Why?

    Will still continue as we goes along.

    The more I know, the more I yet to know!
