You will definitely need a permit or a license to open your business.  However, the requirements will differ depending on what state you live in.  The SBA website maintains a list of business license offices to help you find the information. In addition to a business license, you will need a federal tax identification number and possibly a sales tax license, income tax withholding, and unemployment insurance tax.  Ask your state business office about the insurance requirements for your car wash business. Once you get all of the necessary permits and licenses, keep track of your renewal dates and make a copy for your business records.  You will also need to display your license in your car wash so that customers can see it. The equipment you buy will depend on the type of car wash you have decided to open and the services you offer.  Full service car wash, self-service car wash, and an automated car wash will all have different needs.  You will typically need to buy a washing system (e.g. pressure washer, conveyor, self-service equipment, mobile wash systems), chemicals (e.g. cleaning solutions, wax, spot free rinses, protectants, presoaks, etc.), dryers, blowers, vacuums, brushes, towels, compressors, pumps, and a water system (e.g. boilers, water heater, water filtration, extractor, etc.), and billing system.  If you buy the cheapest version of everything, you might be able to get started for about $2000. If you want a nicer setup, it will probably run you about $5000 or more.  The International Carwash Association has a supplier guide to help you find reputable manufacturers.  Look in trade magazines like Auto Laundry News and Modern Car Care to buy your chemicals.  It is best to buy from big manufacturers.  Make sure the distributor of your equipment is available to service your equipment when needed. Find out how they handle equipment servicing before you buy from them. Use a multifaceted approach to advertise your business that includes flyers, posters, and an online presence. The signage for your car wash should be colorful with clear messaging.  Make sure that people can easily see it from the road.  A popular way to get new customers is by distributing coupons or discounts for car washes. Also, develop relationships with other small businesses located near your car wash.  Social media is an important aspect of marketing these days. Set up a website and establish a presence on Twitter and Facebook.  Make sure any of the paper items that you have include links to your website and social media accounts. Use your website to share information about taking care of your car and other relevant tips. Schedule a visit to your local radio station to discuss your new business. Consider starting a loyalty program. This will encourage repeat customers instead of people who use the coupon one time and never return. A car wash business is very customer-focused.  Your employees should be punctual, efficient, skilled, and have excellent communication skills. As you conduct interviews, pay attention to body language and communication skills to get an idea of how the person will interact with customers and coworkers.
