An APC (all purpose cleaner) like 409, Simple Green, White Lightening, etc....Citrus cleaners, degreasers are all APC styled...All of these can be used inside the car but MIXING them with water is key....Citrus based cleaner are my choice and I mix mine 10/1 water to cleaner..then if that's not strong enough for the inside I can add a bit more. On any APC I would start with this mixture and work upwards from there.
When working on the inside of the car never spray dorectly on the surface, I always spray on the towel then wiper that area...On clear plastics be very careful with those some will cloud up with APC..Common sence is all you need and don't be in a hurry
These can be purchsed at Home Depot, groceries stores, hardware stores...they are about every where
