    Default Gucci Fiat 500 white leather seats stain with small red dye dots from a pink floor mat - What can I do?

    Hello,
    I have a Gucci fiat 500.
    A pink floor mat got wet and stained small red dots all over my white leather seats.
    It won't rub out at all.
    What can I do?

    Here are the stains.
    Red dyes on white leather.
    We have tried a few leather cleaners but none worked.
    I've been told I will have to replace the white leather on my back seat as there are three white panels and all are stained.
    This is what the local detail place told me.
    What do you think?

    Products used for the stain removal in found in the Kit B3.di.
    Note that this kit may not solve the problem created by unknown products with fail attempts compounding to the existing problem. Existing clear topcoating may be damaged or removed during these fail attempts that make the color coating weaker. Restoration of topcoat to protect the colorcoat of the leather is recommended after successful stain removal prior to further protecting it from friction rubs with a non-stick, rub-resistant protector to prolong the wear of the leather finish.


    Leather Doctor® Kit B3.di

    Here are the contents of the kit with their general instructions. . .

    Leather Doctor® Bleach-9.9
    It's for non-absorbent pigmented leather types only.
    This powder bleach becomes pH 9.9 when mixed with hot water to a creamy paste to bleach dyes stains without affecting the color pigment.
    Compound dye stains other components (carbon, grease and shellac or varnish binder) have to be removed prior to bleaching the remaining dye residues.
    Example:
    Ballpoint and Stamp Pad Ink – use Prep-7.7 (a.k.a. Ink Remover-7.7) thru Cleaner-3.8 then Rinse-3.0.
    Note: Not suppose to be used on leather without a non-absorbent finish as it will denature the leather structure - use at your own risk!
    This product is available in 30gm bottles.
    Mixing Instructions:
    The powder Bleach-9.9 has to be mixed into a creamy paste to be applied onto the dye stains so that it remains on top of the surface, otherwise penetrating onto the leather crust cause denaturing to the leather with a yellow stain. This is done by using non-metal tools to mix with added hot water. Advanced formula includes adding Prep-7.7 for a longer more effective suspending and bleaching effect.
    Test:
    Test finishes absorbency strength with Hydrator-3.3 (soak a paper-rag cut out and place over stain for 30mins); if it darkens void the bleaching.
    Perforated and stitching holes are to be avoided too.
    A) Standard Mix:
    A.1] The approximate ratio mix is Bleach-9.9 [3] to Hot Water [1].
    A.2] For example, weight 9gm of Bleach-9.9 into the empty plastic bottle, then add 3gm of Hot Water using the pipette and stir it up to a creamy paste.
    B) Advanced Mix:
    B.1] Bleach-9.9 is first mixed with Prep-7.7 and thereafter hot water is added to mix it to a whitish creamy paste.
    B.2] The ratio by weight is Bleach-9.9 [1] + Prep-7.7 [2] + Hot Water [2].
    B.3] Example of the mix by weight in the bottle may start with Bleach-9.9 [10gm] + Prep-7.7 [20gm]; stir well then add Hot Water [20gm] using the pipette, stir again and leave for 10 minutes or so for it to gel to a whitish creamy paste prior to application.
    Technique:
    The paste is applied onto the stain, preferably use a cut out paper-rag to place on top; this helps the released stains to be absorbed by the paper-rag instead.
    Check every 2 hours to a maximum of 6 hours to see the effect of the bleaching.
    Precaution:
    Use bleach at your own risk, if the finish becomes absorbent (with a darkening effect) stops the bleaching immediately. Clean off sticky residue with Cleaner-3.8 follows with Rinse-3.0 until a squeaky feel. Avoid physical rubbing which may damage the finish during the bleaching process. Blotting action and light agitation using horsehair Brush-3 is recommended.
    pH Neutralization:
    Neutralize the area with a soak of Acidifier-2.0 with a cut out paper-rag and leave to dwell. Change paper when becomes soiled and repeat with double the bleaching time (e.g. a 6 hours bleaching would require a 12 hours neutralizing time).

    Leather Doctor® Acidifier-2.0
    This is a pH 2.0 aqueous leather acidifier; developed for dye bleeding control and neutralizing alkaline exposure that cause marks, streaks, brightness, tackiness or sliminess from spills or cleaners.
    It's for all leather types including Bicast, Pigmented, Aniline, Vachetta, Nubuck, Suede, Hair-on-Hide and Woolskin leather types.
    This product is also available in concentrate to be cut with distilled water at a ratio of 1: 25.
    For severe cases the concentration can be increase to pH 1.0 by cutting with 4 parts of distilled water.

    I believe there is an added problem to be solved, besides those pictures showing the stains is the driver seat shown as picture #6
    “Drivers seat is stained too with dirt and my bronzer from tanning

    Picture #6 should not be an issue once the dye stains are solved with similar procedure.

    First, let us have a test to see the result before the actual removing procedure for a larger area.

    Here are the possible scenarios:

    1] Prep-7.7 effective overnight dwelling solve the problem.
    2] A repeat of the above up to 72 hours may be necessary to see the result as the stain may be compounded with unknown chemistry.
    3] A “plan-B” action using Bleach-99 as a booster into the Prep-7.7.
    4] If the stain is stubborn, not very possible, plan-B can be repeated.
    5] Worst scenario is the requirement of a color touch up due to weakening of the topcoat.
    6] Topcoat touch-up after successful removal at any one stage is highly recommended.


    Let have this picture as a reference:




    Here is the recommended procedure for the dye stain removal:

    1] Select an area for a test as indicate in blue circle.
    2] Cut out the shape from the towel provided.
    3] Squeeze the Prep-7.7 neatly on the stain dots and place the cut-out paper soaking through.
    4] Use food cling wrapper to control the paper and Prep-7.7 from streaking away.
    5] Leave it for an overnight dwell.
    6] Show some pictures if you are doing it accordingly, preferably by the steps.
    7] See if the color is transfer to the paper before removing it.
    8] Remove and inspect to see the result.
    9] Show the result before the next move.

    I finally had time to try it. I applied the 7.7 like you told me and it did fade the red dye quite a bit. However there is still a small amount of red left in the sample area I used. Should I leave it on longer than 24hrs? Also can I use the cleaner and conditioner after the prep7.7?

    Do I use the cleaner to remove the dirt from my drivers seat?





    See examples below, the technique you place paper towel over the stain and let the Prep-7.7 squeeze through without air space – leave it for a 24 hour inspection and may repeat for another 24 hours.

    #1 Dye Stains


    #2 Prep-7.7 Applications


    #3 Place paper towel and squeeze through the Prep-7.7 without leaving air space


    #4 Peel the paper towel off after 24 hours.


    You may clean the rest of the seat in this manner:

    1] Apply Prep-7.7 over the entire area with the foam brush and leave for 15min to a day and let the product works out the soiling.

    2] Sticky residue is removed by Cleaner-3.8.

    3] Rinse with Rinse-3.0 until squeaky-clean.

    4] When dry apply Protection-B+
