Car Wash: DIY vs Professional Service — The Real Numbers
Weekly exterior car wash. DIY uses a bucket, soap, and drying towels at home or a self-serve bay.

The Full Picture
Washing your own car seems like an obvious money-saver, but the time math often surprises people. A quality hand wash takes 45–60 minutes and costs $4–$8 in supplies. A professional full-service wash runs $15–$35, and most touchless or tunnel washes are done in 5–10 minutes.
At 4 washes per month, you're spending 3–4 hours on DIY versus 20–40 minutes for professional washes. The professional option costs roughly $70–$120/month more, but reclaims those weekend morning hours. For people who genuinely enjoy detailing their car, DIY is also its own reward. For everyone else — especially if your time is worth $25+/hour — an automatic wash subscription ($20–$35/month unlimited) is often the smartest option.
