    Default BMW Dakota Oyster - brown belt marks (~6 months old)

    Hello, i discovered a few weeks back some brown marks on my driver's seat. Tried to clean them using the BMW Leather Foam cleaner and Leatherique Pristine Clean with no success, multiple times; also tried with some alcohol, probably rubbed too hard and I feel the upper layer on some very small areas may have been affected.

    I need advice for (1) remove stains (2) repair outer layer (if necessary) and (3) protect with matte finish.

    This is the driver's seat, marks are inside the red area

    This is the left side of the image, enlarged. This is where I believe the outer protective layer is damaged.

    When I rubbed the belt, from which I think I got the color transfer from, with alcohol this is what i got:

    >>> I need advice

    When not leather-safe (that is with a pH value higher then 5) product is used. It is recommended that they are pH re-clean and pH balance with CleanPro-1.5 >
    back to the leather pH neutral of 3 and 5. Alkaline solution will weakens the leather finishes as well as it caused it to swell. The effect of alkaline over exposure is brightening or streaking with tackiness.

    >>> for (1) remove stains

    Dye transfer is limited by “reverse-transfer” technique, this technique utilize Towel-5 to absorb the released dye stain from the working of CleanDye-7.9 (in this situation, otherwise Prep-7.7 is used first and final stain removal if any is work again with CleanDye-7.9). The alkaline pH value will need Acidifer-2.0 to neutralized until a healthy squeak feel.
    Online-Life-Coaching is now available for a fee and a half-hour session will be a guarantee that you do it right the first time (as pictures and words can only convey this much . . .
    However, here is a proven example of how ‘reverse-transfer’ technique works.

    >>> (2) repair outer layer (if necessary) and

    This outer layer is the clear topcoat and is repair accordingly with MicroTop-54S (satin) to match, otherwise Duller-63
    add to the desired luster.

    >>> (3) protect with matte finish.

    Non-stick, rub-resistant protection with Protector-B/B+ helps protect the topcoat finishes.
