If the leather is coated (slick finish with shine) then 1Z Einszett Plastic Vinyl Deep Cleaner will take it off with ease. First found the tip on the company's web page. Makes quick work of getting blue jean stain off light colored seats.
Griot's HD is certainly an excellent wheel cleaner but didn't find it stood out from the pack. When it's on sale probably a good choice; when not see what else is available. Several of these newer generation wheel cleaners just seem to be running a tied race to me.
Meguiars D170 Hyper Dressing at 4:1 works well in the engine bay. Water based so no solvent fumes to worry about. Sonus product works well too but you really have to force yourself not to touch it and seems a bit thicker in application.

All light colored leather is prone to pick up the denim dye. Regular cleaning / treatment will minimize problems. I was at first a bit skeptical but 1Z Einszett Plastic Vinyl Deep Cleaner works great to remove the dye. Be careful in cleaning so as not to remove or scratch the thin layer of...

If you want to polish or wax before paint touch up either of these products can be used to clean just the repair area prior to paint application:
