I noticed these and been only using the car 5 times. Could it be from my dress? I hope these come off? Thanks

I would give a leather cleaner/conditioner wipes a try. I have been pleased by Meguiar's which seems to work fine for around $5. I assume it would simply wipe off. Mini offers a Leather Care Kit for $22.57 but I have not tried it.

 

Find any leather cleaning/conditioning product by Lexol. Should fix it up good as new.

 

I have a gray leather in my truck and it looks exactly like that when it gets dirty. I think mine comes from sliding on and off the seat, getting in and out of the truck.

i have been using Leather Master cleaner by Dr Torx for many years. Also, I have to use a small leather brush to really get it clean....I like it because all it does is clean the leather. Does not put any fake, slippery sheen on the leather like some auto parts store products do.
