A good interior cleaner like Cockpit Premium from Nextzett should remove those marks.

 

Cockpit premium is a good product for plastics, rubber, vinyl etc... but I wouldn’t use it on real leather. Use a leather cleaner & conditioner that is water based. Leather masters or Leatherique are good.

 

Leatherique is by far the finest leather condition on the market.... old skool stuff...

 

2nd Leatherique. Its great stuff

 

The product is actually completely safe for this application since modern automotive leather is coated at the factory. Classic cars benefit from systems such as Leatherique but there is little benefit to using their rejuvenator oil (or any conditioner for that matter) on modern seats due to the coating that is already on there. On its own, the Leatherique Pristine Clean will do a great job with these marks. The Cockpit Premium is water based like Leatherique, Swissvax, etc. The detail shops that I own have been using it for over 5 years without any adverse effects on a wide variety of vehicles.

 

I would still use a dedicated leather product. Its not true that modern leather coatings are impenetrable. I hope Esoteric doesn’t mind me linking to their YouTube clip.

 

Wow thanks for all the replies. I found some leather cleaner from my old car that I forgot about (autoglym) and it's pretty much gone after 3 tries at gently wiping it.

Phew, thought it'd be a lasting mark.

Thanks
