    Default Cleaning of python nubuck?

    I have a pair of shoes that I finally was able to identify as python nubuck. Shoes are white/ivory, and in need of cleaning. I need help figuring out how to clean these since I have been unable to find anything online about how to care for this material. Photos attached. I would be so grateful for cleaning recommendations and care! Thank you!

    The scales of Python skin have the tendency to curl, the curling is due to the diminishing of its original fatliquor (fat and oil) content from about 15% when measured with a leather moisture meter. Thus after the cleaning process, the skin is highly recommended with Hydrator-3.3 to relax the curl and smooth down the curl back to its original, and while still damp Fatliquor-5.0 is replenished repeatedly until the last application is fully saturated, then let it naturally dry.

    Tips - Nubuck:
    Nubuck is also known as velvet suede, that is the reverse side is the typical suede. The smooth grain of the leather is buffed off to produce such a fine velvet, and nubuck is stronger as compared to suede. Nubuck is clean with a NylonBrush-2 and nap is renewed with LeatherEraser-4. The final remapping of the dried nubuck should produce a finger writing effect.

    Tips - Amphoteric Material:
    Python Nubuck is an amphoteric material, (able to react both as a base and as an acid.) Thus is pH sensitive to alkaline solution. All alkaline solutions (with a pH value above 7) will denature the skin. As all skins and leathers have anionic negative (-ve) leather constituents, especially the Faliquor-5.0. When skin/leather is exposed to alkaline solution, it will break the hydrogen-bonding between the skin protein fiber and the leather constituents, thus reverting the skin to rawhide. Alkaline solutions will also age the white skin with yellowing.

    Tips - pH value of solution.
    Since nubuck is absorbent any solution used for cleaning and conditioning will be absorbed into the skin and either will weekend the ionic charges and strengthen its ionic charges between the protein material with the leather constituents. Always check the pH value of cleaning and conditioning solutions prior to use. The leather doctor system is based on tannery science and the suffix numbers represent the pH value of the products, thus, for example, Hydrator-3.3 has a pH value of 3.3 which is on the acidic side of the pH scale.

    Here is the recommended Kit-N3

    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-3.8 follows by RinseNubuck-3.0 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 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-3.0, 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-3.8 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-3.0 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 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 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 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.
