Discoloration of the leather
It's not uncommon for leather products to stain and thus leave marks on other materials. However, if staining does occur, there are various reasons behind it.
If it's suede, it's due to the lint, as suede is sanded during the manufacturing process, and the resulting dust particles can't be completely removed. Rubbing the suede with a light-colored fabric can cause slight discoloration.
With oiled leather (or pull-up leather), things are a little different. This type of leather uses colored wax, similar to shoe polish. Therefore, oiled leather stains more than suede. Heat and humidity play a major role, as they increase the staining.
Leather is discoloring: what to do?!
You can easily do this test yourself by first rubbing a light-colored cloth over the leather while it's dry, then again while it's wet. Lighter staining is acceptable with this method. However, excessive staining (see photo) is problematic and should be discussed with a leather specialist.
