The answer everyone wants: "every 4-6 months for a full detail." The real answer: it depends on how you use your car. I've had customers who need it monthly and others who are fine twice a year. Here's how to figure out what makes sense for you.
The factors that actually matter
Where you park. If your car sits under trees all day, you're dealing with sap, pollen, and bird droppings constantly. Tree sap especially — it bakes onto paint in the sun and eats through clear coat if left long enough. If you park in a garage, your exterior stays cleaner way longer.
Who's in the car. Kids and pets accelerate interior wear dramatically. I've detailed cars where the driver's area is spotless and the back seat looks like a disaster zone. If you've got little ones or dogs riding regularly, the interior needs attention more often.
Your commute. A 10-minute drive on clean roads is very different from an hour on I-5 through construction zones. Highway driving kicks up more road film, brake dust, and debris.
The weather. Here in Snohomish County, our wet winters mean more mud, road salt residue, and water spots. Spring brings pollen. Your car takes more punishment than it would in a dry climate.
A realistic schedule for most people
Full detail (interior + exterior): every 4-6 months. This is the deep clean — extraction, clay bar, wax or sealant, the works. It resets everything and protects your car for the next stretch.
Quick exterior wash: every 2-3 weeks. This doesn't have to be a detail. A basic hand wash keeps contaminants from building up between full details. If you have ceramic coating, you can stretch this longer.
Interior maintenance: as needed. Vacuum and wipe down your dash and console every couple weeks. It takes 15 minutes and keeps things from getting out of hand between professional details.
The real savings: Regular maintenance details are cheaper and faster than letting everything build up. A car that gets detailed every 4 months takes me 2-3 hours. A car that hasn't been touched in a year can take 5-6 hours and cost significantly more because of the extra labor.
Signs you're overdue
If you run your finger across the paint and it feels rough or gritty, contaminants have bonded to the surface. If your interior smells off or the windows have a hazy film on the inside, oils and off-gassing from the dashboard have built up. If water doesn't bead on the paint anymore, your wax or sealant is gone.
None of these are emergencies, but the longer you wait past these signs, the more work (and money) it takes to get things back to baseline.
The recurring detail option
I offer a Clean Club membership — $125 per clean on a recurring schedule instead of the standard $260 one-time price. It's designed for people who want to stay on top of maintenance without thinking about it. I show up on schedule, your car stays consistently clean, and you save money versus booking one-off details.
