Dye Transfer
Is a common problem on lighter coloured leathers; once the dye has imbued it can be very difficult to remove, but this can be avoided by regular cleaning and the use of a protector. The transferred dye will ‘sit’ on top of the protection and can then be cleaned off by regular cleaning. If the dye has penetrated the finish then the finish has to be softened to release the dye (LM‘s Vital) Using a solvent on leather that has a stain or dye transfer will do two things; Cause the dye to 'bleed' into the surface making it even more difficult to remove. Damage the finish requiring replacement.
Dye transfer (from jeans, leather belts, etc) can be very difficult to remove; the longer it is on the leather the harder it will be to remove. Clothing dye normally shows as a greyish bloom in seat area. This is usually caused by dark dye transferring from clothing. Particularly avoid brand new (i.e. never been washed) denim jeans, damp knitwear etc (see Leather Master Strong Effect Cleaner (A-Aniline / Non-Coated) (P-Protected / Coated) (For dye stain that has 'set' use Leather Master Super Remover)
Leatherique Pristine Cleaner offers that it can remove ink and other stains. Its part of a two part system to rejuvinate leather. I cannot honestly say it will work in this case as the pics "seem" to suggest some dye transfer. It would be one of the products I would reach for first however.
