I recently purchased a leather interior for my maxima, and the leather seems to have some spots that need to be cleaned up. What can I do/use for these areas?

those kind of look like leather repair marks...but just try a leather good leather cleaner.

 

Always use a mixture of 4 to 1 water to woolite in a spray bottle to clean leather. It is powerful at cleaning stubborn stains on leather & it is ph balanced so it wont harm the leather either. Its the only thing I use to clean leather. Any lexus or cadillac manual will give these same instructions. Magic eraser with very little pressure with the woolite will work well on the most stubborn stain.
