a professional detailing center will charge about $60 to $100 an hour, and knock cars out in 2 hours, twice the speed twice the cost...... $30 to $50 an hour covers about 99% of the single man mobile detailing services throughout the nation.... for me personally iam closer to about $30 to $35 an hour, and charge an equipment and product fee of $15 to $27, maybe more depending on the job and products used, and i detail part time (2 to 4 cars max a week)
