cleaning sand leather

i just tied to detail my car yesterdy as it started to rain on me.
i cant seem to clean my interior just right,

as for the leather i tried the zaino leather products and i also tried just a wet pc of cloth but it isnt really taking it all out, what do u guys use?

i have like black marks on the edgwe of my seat from hitting ym shoes on the plastic part and also on the bottom of the door , what can i use to take that stuff out as well?

I'm not an expert on the leather, but as far as the bottom of the door, I have the perfect answer. I tried everything on my sand interior, and nothing worked.

I got a "Mr. Clean Magic Eraser" which is a sponge that you wet and then just rub it on the shoe marks. Works great!! I got it at the local Target store, in the aisle with other cleaning products. Comes in a 4 pack. Perfect for those scuff marks on the sand interior (I'm sure it would work with grey as well) I wished I had taken "before and after" pics to show how great it works!!
