    Default Honda Accord 2009 - Rain and Sun leather damages

    Honda Accord 2009
    Forgot to close all 4 windows
    Heavy rain and discovered the next day only.
    Seats were filled with water.
    Next day, the sun dried the seats and wrinkled the leather.
    I will send more pictures later.

    #1 - Picture of the crack hole.

    Hello Roger,
    I appreciate you helping me.
    I completely removed the leather from the cushion.
    Last night I soaked it with 3.3 until now.
    When will I put the 5.0?
    The leather have not gone back to it original shape.
    Picture #2 There is a little stiffness in some portion.
    Picture #3 is the under side of picture #2.
    Thank you.

    #2 - There is a little stiffness in some portion.

    For the area with crack, the underside, will I start with 7.7 then 3.8 then 3.0 the 3.3 then 5.0 or do I wait for the 2.0 first?

    #4 - the top with crack.

    >>> For the untreated ones, do I need to start 7.7 or I will wait for the 2.0 to arrive.
    I am talking about the underside.
    Thank you.

    The underside 'suede' I suppose is clean, so there is no need to clean them, however you may want to use this HideBrush-4 to do the agitation in conjunction with Hydrator-3.3.

    Remember that the product name suffix denotes its pH value and Prep-7.7 is not leather-safe to be use on suede, instead use Prep-4.4 which is leather-safe for suede.

    When you use Acidifier-2.0 (pH 2.0) is to ionic charge the amphoteric leather protein fiber ionic more positive (+ve) since the Fatliquor-5.0 is ionic negative (-ve) for a stronger ionic attraction.

    The three product can be used interchangeable, however always start with Hydrator-3.3 to relax the stiffness first and until achieve the desired softness, Acidifier-2.0 is applied to open up more ionic positive (+ve) charging sites. Then follows with Fatliquor-5.0. Remember that 83.33% of water content will eventually evaporates leaving only 16.66% of the essential fat and oil. When almost dry you may begin to flex or massage the leather until it dry to the desired softness with strength. When fully read with a leather moisture meter or equivalent of an average of 15%, the leather will never crack!

    Any existing crack repairs is done after the leather is well rejuvenated.

    Leather Doctor® Kit, auto leather rain and sun damaged stiffness restoration kit is formulated to restore leather stiffness due to water pH value related issue in combination with excess heat from the sun. Rainwater may be slightly acidic but still higher than the pH neutral (iso-electric point or pI) of leather between 3 and 5, thus causes the leather constituents to leach out especially the fatliquor besides the tanning agent, which result in stiffness. When heat is present during the accelerated drying process it causes the leather fibrils to become stick together due to the “Van der Waal or London Forces” phenomenon. A holistic leather stiffness restoration approach is first performing a restorative cleaning prior to leather rejuvenating it and applying a rub-resistant protector thereafter. Depending on the severity of finishes damages in question, where a new color refinishing is deemed inevitable it will require a related refinishing kit to accomplish the restoration. Embossing damages becomes permanent and is not practical to recreate without pressure, heat and an embossing plate. Shriveled finishes may be too delicate to work during the stretching to relax it and may result in delamination. In such situation the entire damaged panel finishes may be shaved with Razor-60 for ease of relaxing the leather structure with Hydrator-3.3 is recommended. Leather stiffness is perform after CleanPro-1.5 > Acidifier-2.0 system with horsehair Brush-1 and cotton terry towel extraction until the towel shows clean. This restorative cleaning is formulated to remove most general soiling and pH balance the rain water to charge the amphoteric leather protein fiber ionic more positive (+ve) for increase attraction. It is thus logical that the Acidifier-2.0 reaches out to the thickness of the damages. Hydrator-3.3 is the preconditioner for Fatliquor-5.0 as the shrunk leather will need to be relaxed and separate the stick together leather fibrils in order for the Fatliquor-5.0 to reach every inter connecting fibrils behaving like hinges to lubricate and plumps it when dry for the return of suppleness. Rainwater may seep into the damaged areas through the perforation, stitching rows and micro crazing. To follow the path of water damages Towel-5 acting as reservoir containing the Hydrator-3.3 is placed with evaporation control with a plastic sheet or cling wrapper. This technique ensures the Hydrator-3.3 penetrates into the leather structure instead of evaporating and wasted. The dwelling may take up to 72hours with periodic refill until the leather structure is plump with fullness for a re-stretching back to its original dimension. Stretching with a smooth spatula like the end of a spoon indirectly over a plastic sheet helps reduce friction damages to the finishes. When the stretching and relaxing is satisfactory Fatliquor-5.0 replenishing process begins. It is the ionic negative (-ve) charged 16.66% of fat and oil remains behind that will soften or supple up the leather when dry. The 83.33% and the water contents from the Hydrator-3.3 will eventually evaporate. The remaining fat and oil content is measurable with a leather moisture meter or other equivalent and averaging 15% would return to original suppleness. The leather is then flexed or massaged to impart suppleness without cracking it. Protector-B application will reduce friction rubs to prolong the useful life of the finishes.

    This is a three-part system that works on the water/heat damages.

    1) CleanPro-1.5 > Acidifier-2.0 system,

    2) Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system and

    3) Protection-B system.

    1) CleanPro-1.5 > Acidifier-2.0 system: Surface soiling is first removed with CleanPro-1.5 > Acidiffier-2.0 system. Clean-3.8 is the mildest among the cleaner and appropriate higher power cleaning system may be used to match severity of soiling. Example CleanPro-1.5 > Acidifier-2.0 system would increase the cleaning power and also lower the pH value to protonate or pH balance alkaline over exposure. Example, both sea water and saddle soap are alkaline pH value above 8 that may have affect the pH chemistry integrity of the leather structure and a lower pH value cleaner helps to balance the pH value to the original pH value of the leather between 3 and 5. It is recommended that surface soiling is first removed or neutralized prior to proceeding to the next step of leather rejuvenating it.

    2) Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system: Hydrator-3.3 is used to relax the stick together leather structure fibers opening it up so that the Fatliquor-5.0 can easily penetrated into the inter-fibrillary spaces plumps and lubricates it. Easy to access the thickness of the leather through the perforated and stitching holes. Dwelling up to 72hours with control evaporation is recommended to relax the fiber for easier manipulation with force stacking action using a metal spatula or spoon. The mechanical action force to stretch back the shrinkage will surely damage the surface finishes and such procedure need to consider the refinishing option. Otherwise to minimize the finishes damages the force stretching is recommended to be done on the reverse side. The shrinkage finishes is also a burden to the stretching as it holds back with stiffness and Hydrator-3.3 has no effect on it. When refinishes is an option ( than shaving off the color finishes help the leather structure to force stretch back easier. This process of undoing the shrinkage is done in combination with Fatliquor-5.0. Fatliquor helps wedges and lubricates the fiber while it is being separates. Otherwise, when the hydrator dries out before the fatliquor can takes its place the fiber may become stick together again. Leather fibers interlock one another like hinges for flexibility and like metal hinges when it gets rusted and jams tight, a rust remover with mechanical forces works in similar fashion with hydrator before a lubricant like fatliquor is applied to loosen it.

    3) Protection-B system: The protection helps in this instance is to impart a rub-resistant wear to the finishes with a buttery-feel and a classic leather scent. Protector-B+ is the leather scented version.
