    Roger,

    Here are some pics of my couch, chairs, and ottoman to be restored. I do not have any significant damage just normal wear and tear from 15 years of use. I purchased the A3 aniline leather care kit and additional items. Please let me know the best way to use your products. If you need any additional information please let me know.

    Thanks,

    Ken

    We have used a generic leather cleaner and conditioner once every 6 months. We also wipe furniture down with a damp rag in between conditioning when necessary.

    >>> We have used a generic leather cleaner and conditioner once every 6 months. We also wipe furniture down with a damp rag in between conditioning when necessary.

    Leather has a pH value of 3 to 5.
    A damp rag with water has a pH value average 7 (not leather-safe when penetrates the leather).
    What is the pH value of the generic leather cleaner used?
    Are you using a “structural conditioner” or are you using a “finishes conditioner”?
    Do you also have the pH value of the conditioner used?

    For 15 years of product usage, there is lots of residual build-up and pH in-balance that may need to be return to its original pH chemistry integrity, otherwise its leather constituents like the tanning agents, dyestuff and fatliquor hydrogen bond weakens and the leather denatures. So before a restorative cleaning, we may like to know if there is a need to pH balance it to its original leather neutral of 3 to 5 also known as its isoelectric point or pI from non-leather safe products and water?

    We have been using a product called Lexol which is suppose to be pH correct per manufacturer. Before this product we were using a generic brand from a local furniture repair business with a pH of 4 we were told. When we wiped the furniture off with a damp rag it was with distilled water most of the time. I do not know the difference between “structural conditioner” or a “finishes conditioner” but the conditioner we put on would obsorb into the leather and then the excess is wiped off. Not knowing if the furniture is pH correct how can we correct it with the A3 kit?

    pH scale neutral is 7. Leather neutral is about 4, good to know the differences. Note the Leather Doctor’s cleaning and conditioning products name suffix numbers denotes it pH value.


    >>> I do not know the difference between “structural conditioner” or a “finishes conditioner”


    Structural conditioner preserves the leather’s suppleness with pH chemistry integrity from denaturing. Finishes conditioner prolongs the finishes from wear and tear and impart a character touch of feel. Thus soft aniline leather is often described as having “buttery-feel” vs draggy-feel, silky-feel or waxy-feel to bring out its desired tensile-feel.


    >>> but the conditioner we put on would obsorb into the leather and then the excess is wiped off.


    Distilled water would still be absorbed into the leather and all other liquid that may weakens the hydrogen bond between the protein leather fibers and the other basic leather constituents like the tanning-agent, dyestuff and fatliquor (ionic negative charged fat and oil)


    >>> Not knowing if the furniture is pH correct how can we correct it with the A3 kit?

    pH correction is to strengthen the leather ionic positive (+ve) protein fibers with its other ionic negative (-ve) leather constituents. Water has a weak hydrogen bond as well as leather. When temperature changes below it turns into ice and above turns into steam. Leather is both temperature and pH sensitive, that why we see common issue that gradually manifest as stiffness that leads to cracks, or dye bleeding or tackiness due to pH in-balance.
    To correct pH in-balance is to increase the ionic positive (+ve) charged of the protein fiber with CleanPro-1.5 > Acidifier-2.0 system follows with Kit-A3 (preventive, routine, periodic or restorative care system).

    These are the steps you would require for your purpose to return your leather to its leather neutral, isolelectric point or pI chemistry integrity.

    1- CleanPro-1.5
    2- Acidifier-2.0
    3- Prep-4.4 (optional depending on the soiling level especially the heavy used areas- as corrective cleaning)
    4- Clean-3.8 (will need to follow Prep-4.4)
    5- Rinse-3.0 (will need to follow Clean-3.8 - otherwise step 3, 4 and 5 may skip)
    6- Hydrator-3.3
    7- Fatliquor-5.0
    8- Protector-B

    After CleanPro-1.5 follows with Acidifier-2.0, then leather-safe life cycle should begins with “Restorative Care” directive. The 1st step in Restorative Cleaning may skip (depends on soiling severity - check with towel after Acidifier-2.0 the need to further soiling removal).

    Your further questions for clarification are welcome.

    Leather Doctor® Kit-A3, aniline leather, care kit is an innovative leather-safe (pH 3 - 5) system designed for keeping leathers at their highest level of appearance, maintaining its pH chemistry integrity, enhancing their suppleness and prevents premature ageing. Leathers that faced the sun, closed to fireplace and heaters dries out the fatliquor (fat and oil) that keeps it supple sooner than the non-heat exposed areas. The diminishing of the fatliquor through evaporation results in the leather fibers being stick closer together that results in stiffness and when flexed during used will lead to cracks. Periodic use of Hydrator-3.3 to plumps the stick together fibers prior to fatliquor replenishing with Fatliquor-5.0 will keep the leather supple and strong. Thus, reduce the premature ageing of the leather against stiffness and cracking. The surface wear of the leather is greatly reduced with friction noise reduction. This is preventable with a rub-resistant Protector-B that imparts a natural buttery-feel. Periodic cleaning and rinsing with Clean-3.8 follows by Rinse-3.0 to the bare body contact areas like headrest and armrest helps reduce greasy soiling build-up. Restorative cleaning and occasional dye stains removal from new blue jeans is accomplished with Prep-4.4. Note that the mentioned product suffix number denotes its pH value in this leather-safe holistic care system. Shipping Weight Options are available as kit 'Fill-0.6kg' to save on shipping, thus all the 250ml spray bottles have to be cut and filled with distilled water prior to use. Kit 'RTU-1.7kg' is ready-to-use straight from the bottle.
    Leather-Safe System Cycle of Care - Preventive, Routine, Periodic and Restorative . . .

    Preventive Care:
    A non-stick, rub-resistant protection is recommended to be in place before putting the leather to daily use. Protector-B imparts a soft natural buttery-feel that enhances the leather luxuriously to the sense of touch. The non-stick surface shields the leather from sticky soiling thus prolonging the high level of appearance. Rub-resistant ability reduces friction noises that translate into less friction wear. This leather-scented protector diffuses a classic leather scent that boost the sensuous leather more appealing to the leather lover. This preventive care is kept in place at each level of routine, periodic or restorative cleaning cycle. A simply spray and wipe prolongs the need for cleaning heavy soiling. Protecting: Instruction . . . 1- Mist sprays Protector-B spread with lint free towel and is ready for use when dry (leather-scented version is available as Protector-B+).
    Routine Care:
    Routine care includes procedures such as general dust cleaning, attending to spots and stains as required especially the pH balancing of sweat stains from shifting alkaline. Thus prevents leather from tackiness. A routine non-stick rub resistant protection after neutralizing rinse helps keep leather in a more attractive and healthy state while preventing premature wears by . . . 1st step – Rinsing: Instruction . . . 1- Spray Rinse-3.0, horsehair Brush-1 agitates and towel extract until it shows clean. 2nd step – Protecting: Instruction . . . 2- Mist sprays Protector-B spread with lint free towel and is ready for use when dry.
    Periodic Care:
    Periodic care is recommended before soiling causes damages 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 contacts by . . . 1st step – General Cleaning: Instruction . . . 1- Spray Clean-3.8 and agitate with horsehair Brush-1; ensuring a uniform application over the entire surfaces a section at a time. 2- Towel extract until it shows clean. 3- Remaining residues are spray rinse with Rinse-3.0 and towel extract to a squeaky-clean. 4- Let dry and inspect for satisfaction, otherwise repeat cleaning process as necessary or proceed to hydrating. Hydrating is essential to relax and separate the stick together collapsing fibrous structure. Moreover, it is used to check for surface tension from blotchiness prior to fat and oil replenishing by . . . 2nd step – Hydrating: Instruction . . . 1- Spray Hydrator-3.3 to check for an even appearance. Fatliquor evaporates as VOC (volatile organic compound) when temperature rises especially from exposed surfaces. Periodic fatliquoring maintains the leather’s structure integrity and pliability thus strengthen these exposed leather from cracking by . . . 3rd step – Fatliquoring: Instruction . . . 1- Spray Fatliquor-5.0 in like manner as Hydrator-3.3 and let dry naturally. 2- Repeat application in-between drying until saturated. 3- The leather is left for slow natural drying for extra softness. 4- Surface strays are wiped with Hydrator-3.3 to free of sticky residue and let to natural drying. 4th step – Protecting: Instruction . . . 1- Mist sprays Protector-B spread with lint free towel and is ready for use when dry.

    Restorative Care:


    This 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. Using Prep-4.4 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 worked into heavily soiled areas sufficiently to avoid excessive agitation that might damage already weaken finishes especially on heavily used areas by . . .

    1st step - Restorative Cleaning:

    Instruction . . .
    1- Apply Prep-4.4 and agitate with horsehair Brush-1, ensuring a uniform application over the entire surfaces a section at a time. 2- Allow a dwell time of 10 to 30 minutes or before it dries prior to towel extraction until it shows clean. 3- Sticky residue is removed by Clean-3.8 with gentle brush agitation and towel extracts until it shows clean. 4- Remaining residues are spray rinse with Rinse-3.0 and towel extracts to a squeaky-clean. 5- Let dry and inspect for satisfaction, otherwise repeat cleaning process as necessary or proceed to hydrating. Hydrating is essential to relax and separate the stick together collapsing fibrous structure. Its surfactancy helps check for surface tension of blotchiness prior to fat and oil replenishing.

    2nd step – Hydrating:

    Instruction . . .
    1- Spray Hydrator-3.3 to saturate with an even appearance to soften up the leather. 2- Let dwell 10 to 30 minutes and towel extract wick up soiling until it shows clean. Fat and oil replenishing maintains the leather’s structure integrity and pliability thus strengthen these exposed leather from cracking.

    3rd step – Fatliquoring:

    Instruction . . .
    1- Spray Fatliquor-5.0 in like manner as Hydrator-3.3 and let dry naturally. 2- Repeat application in between drying until saturated. 3- The leather is left for slow natural drying for extra softness. 4- Surface strays are wiped with Hydrator-3.3 to free of sticky residue.

    4th step – Protecting:

    Instruction . . .
    1- Mist sprays Protector-B/B+ spread with lint free towel and is ready for use when dry.
