Look for leather care

Actually the search button might not help him as much as some new info I've come across.

CFoote found a detailing forum that said Mr. Clean Magic Erasers work wonders. Don't over do it..and leather seats come out amazing.

Pat did his and nearly died from the dirt.

I did mine with the Meguiars three stage thing
First the cleaner, then the conditioner, then the spray

I like Lexol. I left the windows down in the rain one night this summer and the front seats got really soaked. I dried them as best I could with towels, then applied Lexol liberally to the wet leather. When they dried out, they were softer than they have ever been. Lexol directions don't say to wet the leather, but it really worked great for me.

I would NOT suggest Mr. Clean erasiers. I have seen the strip paint right off walls. IDK what chemicals are in them, but I sure as heck wouldn't want that on my leather.

The information was found on a detailing forum. CFoote and 1993 Sle have both used them on their seats wtih no adverse issues.. I believe the key would be to go at it gently.

I wouldn't use a Mr Clean eraser either. But I have read they work well for scuffs on the plastic. Just use any general cleaning product to clean them, and then use any leather conditioner. Meguiars is pretty good. Otherwise there are a lot of good cleaners and conditioners online at places like autogeek.com.

Detailing forum or not, I personally wouldn't do it. You dont know what kind of chemicals were left on the seat or what any possible long term impact will be due to the harsh chemicals.

But that is just my 2 cents

As normal maintanance, I use Zymol leather cleaner and the conditioner. For "first time the leather has been cleaned since it was yanked off the cow", I go use Kiwi products, like the saddle soap and the mink oil. Takes a while but it really softens up the leather. And the best place to go to if you have some paint wore off the leather is a shoe shop and look for the a shoe polish that is close to your color to fill in scratches. I have some dark grey polish that I used on my SLE and it really hid the scratches well for a few months before I had to reapply it.
