I know a group at our local airport that charges $50 to wash a 150, $75 for
a 172/182, $100 for a twin etc. That's top to bottom, de-bugged, de-greased,
clean glass. So for a wax and interior clean you could probably easily
double the labor.

I've seen an A&P with professional cleaning equipment wash a plane the size of a
172 in about an hour. Since the shop rate was $60/hr, $75 would not be
unreasonable at all. Waxing takes *much* longer, so I would expect probably four
times the cost if you added on a wax and interior cleaning.
