Vinyl Care (roof top and bench seats)

I just acquired a nice '76 Dart Sedan. The vinyl roof top is original and in good shape. Can someone recommend a product other than water and soap to clean it and won't leave it greasy and dried out. I have had very bad results with Armor all in the past. I am worried of using a product that well lubricate/swell the vinyl top and once it dries out cause it to rip or make me a slave to it. In the meantime I'll keep the car out of the sun under a good cover.

Also, can someone recommend a product for the interior vinyl front and rear bench seat? Trying to bring the car back to life. Thanks.
