Decide first whether you'll work mobile or from a shop, because that choice sets your equipment, your water plan and your insurance. Then find out where your wash water is allowed to go before you wash a car for money, register the business and ask your state whether detailing is taxable, insure customers' cars while they're in your care (ask about garagekeepers coverage), keep a safety data sheet for every chemical, and price from your own hours.
Decide how you'll deliver the work before you buy anything: the model sets your equipment, water plan, insurance questions and how many cars you can finish in a day.
| Mobile | Shop | |
|---|---|---|
| Where you work | Customers' driveways, workplaces and lots, with permission | Your own bay, with cars dropped off or picked up |
| Water and power | You bring both, or use the customer's with permission | Plumbed water and wired power |
| Wash water | Captured on site, or kept to a minimum with rinseless methods | Goes down drains the landlord and the sewer utility have approved |
| Correction and coating | Needs a garage or covered space at the customer's | Controlled light, temperature and dust |
| Check first | Local water rules and each property's permission | Zoning, the lease and where the wash bay drains |
Mobile avoids rent and a lease, so it's the lighter commitment at the start, but it costs you drive time, setup on every job and a calendar that depends on the weather. A shop adds a monthly bill and lets you run multi-day correction and coating jobs, keep more than one car moving and work through a rainy week.
If you're leaning toward a shop, get three answers before you sign a lease: whether zoning allows vehicle washing at that address, where the wash bay drains, and what the landlord and sewer utility require before wash water goes down it. Renting time in someone else's bay, or sharing space with a tint or wrap shop, lets you test the shop model first. A home garage sits in between: check zoning, any HOA or lease rules, and the same water questions as a mobile job.
Example: These figures are invented to show the math. Say a bay costs $1,800 a month in rent and utilities, and an average job there leaves $120 after supplies and your own pay for the hours. You need 15 of those jobs a month (1,800 ÷ 120) before the space pays for itself. If the bay lets you sell two coating packages a month that each leave $600, those two cover $1,200, and five ordinary jobs cover the remaining $600.
Know where every gallon goes before you wash a car for money. Detailing water isn't just soap: it carries degreaser, wheel cleaner, brake dust, road grime, oil drips and dressing overspray, and the water your extractor pulls out of carpets and seats is dirty too. EPA's stormwater guidance on vehicle washing notes that wash water can carry contaminants from fluid leaks, normal vehicle wear and the cleaning process itself, and that wash water sent to a sanitary sewer may need treatment, so permission from the sewer authority comes first 1. In a shop, the building's drains decide where it goes. On a mobile job, you do.
The answer depends on where you work, so call the stormwater program in every city or county you'll serve (try public works if you can't find one), plus the sewer utility if captured water will go down a sanitary drain. Ask:
Write down each answer with the office's name and the date, and keep it in the van.
A mobile capture setup has four parts:
Keep the dirtiest work, wheels and any degreasing, on the mat. Leave engine bay degreasing off the mobile menu unless you can capture every drop of it.
Rinseless washes (a diluted wash solution and towels, with no hose rinse) and waterless products (spray on, wipe off) leave little or no water to manage. They suit maintenance washes, lightly soiled cars and places where you can't lay out a mat, such as parking garages and office lots. A car caked in mud or road salt still needs a rinse and the capture setup, so price and schedule it as a different job.
Check three offices before you take your first payment.
The state. If you form an LLC or another entity, register it with your state's business filing office, and ask whether a business name that isn't your own needs its own registration.
Your city or county. Ask the business licensing office:
The state revenue department. Whether detailing is taxable depends on the state, and so does the treatment of anything you sell. Ask:
Register before your first taxable sale, and have a CPA check your setup if the answers are unclear or you'll work across state lines. How to invoice auto detailing jobs covers showing tax on invoices, plus deposits and no-show policies.
In detailing, the most valuable property on the job belongs to the customer. You hold the keys, move the car, run machines on the paint and use chemicals on leather, trim and glass. Build your insurance around that, and get quotes before you set prices.
General liability insurance covers claims that your business injured someone or damaged their property. Read its exclusions with the agent, especially any exclusion for property in your "care, custody or control." A car you're washing, polishing or parking is in your care, so ask directly whether this policy pays if you damage it.
Ask about garagekeepers coverage for customers' vehicles in your care, then ask:
Buy for the services you'll sell in the first few months, not for everything you might add later.
| Job | What you need |
|---|---|
| Wash and decontamination | Pressure washer, foam cannon or pump sprayer, buckets with grit guards, wash mitts, wheel and tire brushes, drying towels or a blower, iron and tar removers, clay bar or clay mitt |
| Interior, glass and trim | Wet/dry vacuum, hot water extractor, steam cleaner, brushes, an air blower for vents and seams, interior and leather cleaners, glass cleaner, trim dressing |
| Paint work, when you add it | Dual-action polisher, pads and polishes, inspection lights, paint depth gauge, masking tape |
| Mobile water and power | Clean water tank, pump, hose reels, generator or battery power, containment mat, recovery pump or wet vac, holding tank, canopy for shade |
| Safety | Nitrile and chemical-resistant gloves, eye protection, a respirator where a product's SDS calls for one, spill kit, first-aid kit, fire extinguisher |
| Paperwork | Phone for booking, photos and invoices, condition report forms, a binder or phone folder of SDS |
A few decisions matter more than the brand names:
Get the safety data sheet (SDS) for every product you use from the supplier or the manufacturer's website, and read it before the product's first job, not after a splash. Look for:
Keep the sheets in the van and update them when suppliers send new versions. Once you have employees, this becomes a legal duty, not just a habit: OSHA's Hazard Communication standard requires employers with hazardous chemicals in the workplace to have labels and safety data sheets for exposed workers and to train them 2. A few more habits:
When you hire, hiring your first detailer covers chemical training, responsibility for damage and pay.
Price from your own time and costs, not a competitor's flyer. Time every job by vehicle size and condition, including the parts customers never see: setup, water capture, teardown, emptying the holding tank and driving.
Example: These figures are invented to show the math. Say a full detail on a midsize SUV takes 4 hours of hands-on work. A mobile job adds 30 minutes to set up the mat, water and power, 30 minutes to pack up and deal with the captured water, and 30 minutes of driving: 5.5 hours per car, so two full details make an 11-hour day. At a labor rate of $60 an hour, the mobile job needs $330 to cover your time, not the $240 the hands-on hours suggest, before supplies.
Set that rate with how to set your labor rate, then use how to price auto detailing to turn hours into packages, upcharges and travel fees.
Launch with a short menu you can deliver to the same standard on every car, then add services as your skills and equipment grow.
Only with their permission, and ask when they book, not when you pull up. Find out where the spigot and an outdoor outlet are, and whether that outlet can run your equipment without tripping a breaker. Using their water doesn't change where the wash water may go, so lay out the mat either way. Carrying your own water and power lets you take jobs at workplaces and apartment lots, where there may be nothing to borrow.
Only with permission from the property owner or manager, ideally in writing (an email or text works), before you book a customer there. The customer's permission isn't enough on property they don't control. Ask where you may park and work, what hours are allowed, whether you may use water or power on site, and whether they'll want a certificate of insurance. The local water rules still apply, so rinseless and waterless methods are often the practical choice in these lots.
Stop, photograph the damage and tell the customer right away, before they find it. Compare it with your arrival photos and condition report. Call your insurance agent before you promise a repair or a payment, and read your policy's claim-reporting terms when you buy it, not after a loss. Decide in advance which small problems you'll fix on the spot, such as re-cleaning a missed area, so you can make those right before you leave.
Rules and figures change, and many requirements vary by state and city. Check the current version of each source and your local authority before acting, and talk to a licensed professional about your specific situation.
