    1. Cut a washable paper towel (this paper has a smooth surface for better surface contact and does not tear during application) the size of the blue mark spot.
    2. Apply Prep-7.7 to the spot.
    3. Place the cut out paper towel over it.
    4. Squeeze out any air bubble using horsehair Brush-1 moving from center outwards.
    5. This paper saturated Prep-7.7 becomes an extension of the leather surface.
    6. Allows the Prep-7.7 to do its penetrating, lubricating and suspending action.
    7. As soon as the dye stains is suspended, it will be absorb by the more absorbent paper towel instead of still remaining on the leather surface.
    8. This innovative “reverse transfer” technique minimize the use of physical forces thus reduces potential prior weaken finishes further.

    Note: leathers that has a healthy topcoat, stains stays on the surface, thus removal is easier. Worn or deteriorated topcoat allows the suspended stains to be reabsorbed by the vulnerable colorcoats thus will require repeats to eventually reverse transfer all the stains away from the topcoats.
    When dyestains takes more than one day to be transfer, it indicates that the topcoat is missing and is recommended to refinish accordingly with MicroTop-54 with choice of gloss, satin or matte luster.
    Preventive maintenance is by the application of Protector-B+ that imparts a naturally buttery feel to reduce wear to the topcoats and part of routine maintenance care.

    Please post questions you may have to s speedy and efficient dye stain removal holistic processes.

    Leather Doctor® Kit Sa7.di, micro-pigmented leather dye and ink stain removal kit is an innovative concept of removing blue jeans dye and ink stains featuring a “reverse transfer” technique utilizing a paper towel over the dwelling Prep-7.7 for micro-pigmented, antiquing and two-tone leathers that normally has a satin luster effect. The micro-pigmented and fashion effect varieties have a more delicate finish and is easily removed during stain removal and color refinishing is the norm on most wear areas. Prep-7.7 works by penetrating, lubricating and suspending the stains on dwell time and the paper towel reverse absorb the stain instantaneously from the leather. Prior failed attempt with set-in stains may require the help of Bleach-9.9 as booster to the Prep-7.7 to remove the residual stains. Clean sticky residue with Cleaner-3.8, rinsed with Rinse-3.0 and neutralized with Acidifier-2.0 when Bleach-9.9 is cooperated. Hydrator-3.3 relaxes stiff leathers and eliminates surface tension prior to fat and oil replenishing. Fatliquor-5.0 rejuvenates the leather structure with softness and suppleness when dry. MicroTop-54S is an option for renewing the finish from friction wear. Protector-B+ imparts a non-stick rub-resistant protection with a buttery feel that shield against sticky soiling and reduce friction noises. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe dye and ink stain removal system.


    Testing with Prep-7.7
    Note that secondary colors are delicate and color refinishing is the norm after stain removal on wear areas.
    1. Cut out a piece of paper towel from the kit not bigger than our thumb size and soak it with Prep-7.7.
    2. Test it on the worst stains area and inspect every 24 hours with fresh application until the stain is gone.
    3. Observe if there is sign of stain removal, if it does, the stain will eventually be remove with repeat application.
    4. To secure the test patch from dislodging wrapped it over with see through cling wrap.
    5. When stain is removed with satisfaction, clean off the sticky residue with Cleaner-3.8 follows with Rinse-3.0 until a squeaky-feel.
    6. Apply a soak out paper towel with Acidifier-2.0 over the area until dry to strengthen the finish prior to topcoat application.
    7. When test after 72 hours shows poor response, Bleach-9.9 may be used to boost the Prep-7.7.

    Mixing Ratio (1: 2: 2)
    1. A mixing ratio guide by weight is 1 part Bleach-9.9: 2 parts Prep-7.7: 2 parts Hot water.
    2. From the mixing bottle, a small test portion Bleach-9.9 is first added into the bottle follow with Prep-7.7 adding and stirring into a paste.
    3. Hot water is dripped into the bottle using the pipette to activate the bleach and stirring into a creamy paste.

    Testing with Bleach-9.9
    1. Apply onto an inconspicuous or hidden area and leave it for a 12 hours inspection for discoloration.
    2. Remove residue with damp wiping and cleaning sticky residue with Cleaner-3.8 follows with Rinse-3.0.
    3. Cut out a paper towel, soak with Acidifier-2.0 and place on the test spot until naturally dry to neutralize the alkalinity.

    If testing with Bleach-9.9 bleach shows side effect, abandon and continue only with Prep-7.7.

    Actual Application
    Repeat testing successes to the actual application.

    the only solution is to give any dark coloured clothing a minimum of 3 washes before sitting down in the particular garments that have raised concern. Even after washing this many times, please do so with caution.
