    Default What is this

    Hi Roger ,

    Could you tell me what kind of leather this is? It's a Chanel bag. I want to clean it but puzzled as to what kind of leather it is.

    Thanks

    This is a beautiful 'Nubuck" leather!

    Nubuck is top-grain cattle leather that has been buffed on the grain side, or outside, to create a velvet like texture or nap. It has the characteristic of a slight nap, with the softest “hand” or tactile feel. Although nubuck is aniline dyed through it is commonly finish with a surface dye sometimes incorporating micro-pigment to cover up some natural blemishes. It looks similar to suede, but the difference is that suede is created from the flesh side of leather, whereas nubuck is created from the grain side of leather. As both nubuck and suede are napped leather, it is often incorrectly identified as suede. Leather is both hydrophilic and oleophilic, nubuck especially with its open nap absorbs both water and oil more readily, than any other smooth leather. It is generally more expensive than suede; fashion types include embossed, oil and wax pull-up effect. Fatliquor plays an important role when comes to maintenance to both reduce ingress of waterbased and grease stain; plumps the leather with fullness, reduces creases, and wrinkles. Leather protein-fiber component is amphoteric therefore, a leather-safe (pH 3 - 5) care product system is highly recommended to keep them clean while maintaining their chemistry integrity

    Here is the care Kit-N3 for the different level of care cycle . . .

    Leather Doctor® Kit-N3 - nubuck care kit is an innovative leather-safe (pH 3 - 5) system formulated for keeping nubuck at their highest level of appearance at all time, maintaining its pH chemistry integrity, enhancing their suppleness and prevents premature ageing. Nubuck that faced the sun, closed to fireplace and heaters dries out its fatliquor (fat and oil) sooner than the non-heat exposed areas thus compromise its suppleness. The diminishing of the fatliquor through evaporation results in the fibers structure 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 maintain its suppleness and strength. Thus, reduce the premature ageing against stiffness and cracking. The surface wear is greatly reduced in preventive care with a rub-resistant Protector-S (leather-scented version Protector-S+) that enhances a non-stick silky-feel to shield against sticky soiling. Periodic cleaning and rinsing with CleanNubuck-4.5 follows by RinseNubuck-3.5 to the 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 for nubuck. This kit comes with reduced weight option to save on shipping thus all the 250ml concentrate ratio spray bottles have to be cut and filled up with distilled water prior to use.

    Nubuck-Safe System Cycle of Care - Preventive, Routine, Periodic & Restorative . . .

    Preventive Care:
    A non-stick, rub-resistant protection is recommended to be in place before putting the leather to daily use. Protector-S imparts a soft natural silky-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-S+ (optional) 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 brush prolongs the need for cleaning heavy soiling. Protecting: Instruction . . . 1- Mist sprays Protector-S/S+ brush to distribute evenly and when dry brush again to raise the nap and is ready for use.

    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 RinseNubuck-4.5, nubuckBrush-2 agitates and towel extract until it shows clean. 2nd step – Protecting:Instruction . . . 2- Mist sprays Protector-S brush to spread evenly, let dry and brush again to raise nap and is ready for use.

    Periodic Care:
    Periodic care is recommended before soiling causes damages to the nap. This keeps nubuck consistently clean and healthy at all times. Body contact areas would require more frequent attention than the unused areas. While the headrest, hand rest, handles etc. gets the most of body oil and sweat contacts by . . . 1st step – General Cleaning: Instruction . . . 1- Spray CleanNubuck-4.5 and agitate with nubuckBrush-2; 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 RinseNubuck-3.5 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 its structure integrity and pliability thus strengthen these exposed areas from cracking by . . . 3rd step – Fatliquoring: Instruction . . . 1- Spray Fatliquor-5.0 in like manner as Hydrator-3.3 and let dry naturally. 2- Then repeat application in-between drying until saturated. 3- It 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-S spread by brushing, when dry brush again to raise nap and is ready for use.

    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. Detailing nubuckBrush-2 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 CleanNubuck-4.5 with gentle brush agitation and towel extracts until it shows clean. 4- Remaining residues are spray rinse with RinseNubuck-3.5 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 spread with lint free towel and is ready for use when dry. Note: Use Degreaser-2.2 > Acidifier-2.0 > Hydrator-3.3 system for degreasing instead from body oil, grease and sweat.

    Leather Stain Identification:

    Appearance - Stain identification by appearance will show whether it the characteristic of a spill, rub-on, penetrated or deposited. It may also reveal dye or finishes damages cause by the stain.

    Odor - Stain identification by smell can be very helpful in positive identification. Some of the more common odor may be moldy, smoke, putrid or ammonic from urine.

    Color - Stain identification by color will also give a clue to the staining material. If the stain is red, it could be beverages, nail polish, lipstick, blood, or some other things. Color identification may not necessary be right; with time, a red bloodstain may turn to a stain that is tan to black. The color of the leather may mesmerize or alter the color of the stain.

    Feel of Hand - Stain identification by feel of hand may help determine the stain types. For instance, if it is sticky and red it could be candy, beverages or other things that have sugar in them. If the stain is brittle and stiff, it may be nail polish, shellac or paint. If it smears, it may have grease base to it, such as lipstick.

    Location - Stain identification by location may give a clue as to the makeup of the staining substance. If it is dark at the headrest or the edge of the armrest, it is most likely stain by body oil, grease and perspiration by hand or by head.

    Buildup or Absorbed - A stain may take several appearances. The stain may be lying on top of the leather (buildup) on most pigmented leather or absorbed into the leather on most unfinished, aniline and nubuck leathers. Naturally, it could also be a combination of absorbed and built up. If it has been absorbed, this will be an indication that it was a liquid when it penetrates the leather. It should also alert us that it may have chemically changed the dye of the leather. An example of this would be a perspiration stain that has reacted with the leather dye and changed it in some way. This would occur more likely on dyed absorbent leathers. The perspiration could also have weakened the fibers of the leather. In any event, this leather may show a marked color change in that area after spotting, and possibly after cleaning. Examples of built up stains are paint and some foodstuff, etc. Examples of absorbed stains are beverages, wine, tea, coffee, etc. A combination stain may be lipstick, ink, mustard, etc. it will have part of its staining matter absorbed into the leather and part of it accumulated on the surface. A stain may also be a substance that has wet solvent-soluble and dry solvent-soluble components combined. An example of this would be gravy which contains grease, flour (from plant), and milk (from an animal). 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. When identifying stains always try to a determine whether they are of a protein, cellulose, oil based, or a colloidal make-up nature. Three common types of soiling or stain are solvent-soluble, water-soluble and insoluble. Stains are frequently of a combination nature, and in most instances, there will be no information from the customer regarding the stain especially if they are bought used.

    Identify the leather problem from the left column with the top row product recommended and the numbers denotes the sequence of steps. When leather have compound issue combine the soiling, stain and odor types as the cleaning phase-1 and the leather rejuvenating with Hydrator-3.3 > Fatliquor-5.0 as the second phase-2. Structural problem as third phase-3, Finishing as phase-4 and protection of the finishes as phase-5.

    Redyeing is always the last resort.

    The richness of the coloring may be activated by Hydrator-3.3 > Fatliquor-5.0 Hydrator-3.3 system and should be attempt first for satisfaction prior to redyeing.

    Here is the recommendation.

    1- Wet out the entire bag with Hydrator-3.3 and leave it overnight (or up to 72 hours by periodically inspecting for even dampness) in an enclosed bag to prevent evaporation.

    2- This process will allow the dyestuff within leather structure to redistribute itself and refresh the surface.

    3- Wick-up soiling particulates is work with Eraser-4 and nylon Brush-2 and towel extract until towel shows clean (color transfer to the white cotton terry towel is a good sign that the dyestuff has redistributed).

    4- Proceed to Fatliquor-5.0 until the leather is saturated (fatliquor will saturate the color intensity further for a deeper richer color).

    5- Leave to natural dry.

    6- When crispy dry the surface may turn dark is where the soiling particulates and some dyestuff have migrate to the tip of the fiber.

    7- The dry soiling is erased with Eraser-4 in combination with Brush-2 to reveal the refreshed coloring.

    8- With satisfaction of color appearance Protector-S/S+ is applied and when dry brush to a finger-writing-effect. Otherwise skip step 8 for a redyeing/coloring before applying Protector-S/S+

    Show pictures of each to the above steps for me to correct if any.

    Have you applied Fatliquor-5.0 a few rounds till saturation for leather suppleness?


    1- Then, fill the bag and massage, pull stretch back in shape.
    2- Brushing and towel extracting while damp further removes soiling that resurface.
    3- Put the bag in shape and let it slow natural drying.
    4- When crisp brush off surface to reveal the clean nubuck.

    ​Here are pictures as I am wiping and brushing. I don't see any dirt on the white towel, just die. Is that normal? Do I keep wiping until the black goes away?

    Use normal cotton terry towel for wet extraction!

    Any surface that shines may be soiling on the nubuck.

    The darkness will be remove completely when the nubuck is crispy dry by brushing.

    Please,

    Transfer all the pictures and questions back here for easy reference.

    Make sure the bag is stuff full to keep in shape while it is drying.

    When crispy dry show picture again before you brush.

    These are pictures after intense brushing. What do you think? Should I try to dye it, or leave it alone?

    Leave it alone (or do you have any comments?)

    Have you applied Protector-S/S+?

    When crispy dry again after Protector-S/S+, you may brush it again for that silky 'finger-writing-effect'!
