There are products on the market for cleaning suede, immitation suede and other fine leathers.
What I would suggest you do is go to
www.google.com and type in:
"Cleaning King Ranch Leather"
Be sure to put in the " as this will limit the search. You will find a good number of sites you can go to get information and products to use. I have done it
Out of the country at present and do not have the product information I have to assist you, but this will get you what you need.
One thing I can tell you is not to use "water." There are some treated clothes that are used to clean suede leather.
