I just spilled some coffee on the front seat. Immediately I use tissues to absorb the coffee and then cleaned with paper towel dampened with warm dish soap solution and rinsed with wet paper towel. After 40 mins commute the spots are dried and doesn't show stain, thankfully. (But I can still smell the coffee from center storage which also got some on.) Of course I was critiqued by wife. And she worried about the heating function. I don't know the structure beneath the seat but I don't think the small amount of coffee on surface can get to the heating element that fast. Can anyone more experienced provide thoughts on this?
