For the KR seats?

From what I have seen and read about KR leather it should be a good match.
Leatherique is a mild effective leather cleaner and very good conditioner.  It cleans by heat and the cleaning oils floating stuff to the surface to be wiped off.
Very dirty seats require 2 or more applications of the cleaner but if the leather is in pretty good shape this is one of the best, long lasting products I have used.
It's the most expensive leather product I have used also.
You will probably use 2X as much of the Cleaner as you do the oil.
