>>> It's a BMW branded conditioner.
The conditioner used is not “leather-safe” to the leather structure (only meant for the finishes) that is why it stained the cross section (suede) of perforated holes, which is the leather structure. Surface finishes conditioner like Protector-B will not have such problems, for your information.
>>> Is there a way to remove this?
You will need a “leather-safe” degreaser like Degreaser-2.2 to break-up the conditioner and cause it to suspend. This has to follow with a rinse with a “leather-safe” Hydrator-3.3 to either helps it to disperse horizontally and any residue removed from the perforated holes.
The technical difficulty is the physical removal of the soiling particulates from the perforated cross section. The only practical solution is using a tooth prick to file it up and down each of the perforated holes.
Tips:
Any penetrated soiling degreasing will also stiffen the leather when dry and Fatliquor-5.0 is highly recommended after the appearance improves with leather rejuvenating it with Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system
