    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

    Tell us what care products you have used for the last 15 years?

    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).
