There really is not an easy way to get the treatment out of the covers. The best thing is to just wear them in with use. I find that when they are fresh that keeping a couple of old beach towels in the truck helps as you can drape them over the seats if you are in nice clothes. After awhile it will begin to wear off and you will not get as much transfer. When I first restored my 715 in 2004 any time I came in from the garage you could smell it on me, and the wife would complain, now I barely notice it anymore.
