What is the best way to clean none leather seats?

Just want to find out what you Guys/Girls using to clean the none leather seats. I always had leather in the car and it seems they are easier to clean. Since my Mini has been the transporter of choice lately I have to remove Basset Hound Slapper and the Hang Over make up from the Girlfriend from the Las Vegas Trip. I was thinking of warm water and some gentle soap but if anybody has a better idea please let me know. Thank you
