I detail on the side.. Today a customer got a full interior vacuum/scrub down of all carpets, door jambs, trunk jamb, Windows cleaned, strip wash, polish, glaze, wax, tires scrubbed, wheels cleaned, black plastics rejuvenated, and I think that's it.. Took about 5 hours.
Op, it also depends on what product you use. Cheaper products will be harder to apply and harder to wipe down. I use stuff that wipes on super easy and off just as easy, but is somewhat pricey to average consumers. Look up www.adamspolishes.com
and also check out www.detailedimage.com
and look into Chemical Guys.
