What does it cost to start?

The biggest choice is whether you carry your own water and power. That one decision moves your budget from hundreds of dollars to thousands. Here are three real setups, priced from retailer pages on October 8, 2026.

Setup What’s in it Listed price
Rinseless starter Optimum No Rinse Wash & Wax 32 oz ($19.99), Metro Vac Vac ‘N’ Blo VNB-94BD ($374.99, on sale), Griot’s Garage G9 polisher ($169.99, out of stock at that seller) about $565
Packaged kit + water rig Detail King Weekend Warrior kit ($2,240) and DK2000 pressure washer with the 60-gallon tank option ($3,169) $5,409
Full kit + power + water Detail King Start-Up Kit 1 ($5,226), Mobile Wash System with generator ($4,825), Ralda’s 80-gallon tank ($550) $10,601

The vacuum was on sale (listed $394.99 before the discount), and the polisher showed as out of stock at that seller, so the rinseless total assumes it comes back at that price. Sales, shipping, and tax will change what you actually pay.

What gear do you need first?

You need gear for a full interior and a safe exterior wash. Everything else can wait until paying jobs justify it.

  • A wash method. A rinseless wash product lets you wash with a bucket and towels instead of a hose. rinseless car wash concentrate
  • A vacuum. You’ll vacuum every car. The vacuum in the table also works as a blower. portable car detailing vacuum
  • A polisher. You need one for wax, sealant, and light paint correction. The polisher in the table was out of stock at that seller, so check other sellers or the maker’s site. random orbital car polisher
  • Towels, brushes, and chemicals. These add up fast, and packaged kits bundle them. microfiber detailing towel bulk pack

Do you need a water tank and generator?

Only if you want full pressure-washer washes at homes or offices where you can’t use the customer’s water and power.

One kit maker says its start-up kits leave this gear out and that you need your own equipment to wash with if you go mobile. It also notes that a mobile pressure washer has to pull water from a tank, and that this takes a specialized pressure washer. Starting rinseless and buying a rig once customers ask for full washes keeps your first outlay low.

Other things that move your cost are the services you offer (see our ceramic coating cost guide for what customers pay for that work), whether you use a vehicle you already own, and whether you buy a kit or piece by piece.

How do you set up the business side?

Work through these steps in order. Each links to an official source, because the rules depend on where you live. This is general information, not legal or tax advice.

  1. Pick a business structure. Sole proprietor, LLC, and others differ in taxes, paperwork, and personal liability. The SBA’s guide to choosing a business structure compares them.
  2. Register your business. How and where depends on your structure and your state. The SBA’s register your business section explains when you register with state and local governments.
  3. Get a tax ID if you need one. The IRS explains who needs an Employer Identification Number (EIN) and lets you apply online. It’s free, and the IRS warns about sites that charge for it.
  4. Check licenses and permits. The SBA notes that license requirements and fees vary by business activity and location. Check with your state and your city or county, and ask your city how it handles wash water and storm drains.
  5. Get insurance. You’ll be working on other people’s vehicles, often on their property. The SBA’s business insurance section lists six common kinds. Talk to a licensed agent about what your work needs.
  6. Open a business bank account. The SBA says it helps you stay legally compliant and protected. See its launch guide.

How do you set your prices?

Start with your costs, not your competitors’ prices. Add up your time, products, fuel, and gear payback per job. That’s your floor. Then look at what local detailers publish. Our guide on how much to charge for mobile detailing walks through the method, and mobile detailing cost by vehicle size shows what customers expect to pay.

Common mistakes to avoid

See also mistakes to avoid when booking a detail for the customer view.

  • Buying the full rig before your first customer. Start lean and upgrade when bookings justify it. Customers will also ask about insurance, as our guide to finding a reliable mobile detailer shows.
  • Skipping the local rules check. Licenses, permits, and wash-water rules vary by place.
  • Pricing below cost. A busy calendar at a loss is still a loss.
  • Paying for an EIN. The IRS application is free.
