I use Mr. Sheen on my plastic bits, and they scrub up well. I use glass cleaner on the inside of the windows, and I didn't get any leather in my new car, but in the old one, I used baby wipes to give them a good clean.
The best thing to use is is just a very mild mix of all purpose cleaner and warm water but only if there is dirt. usually a damp cloth is enough. As you have a design you will have half leather so get some leather cleaner/conditioner. I have the gliptone stiff and its very good.
For my glass i use chemical guys streak free finish.
