How are the top car wash companies ranked?

Our top car wash companies list is ranked by the number of locations each car wash business operates. Companies with more active locations appear higher on the list, making this ranking a simple way to compare the size and reach of major car wash brands across the industry.

How many car wash locations does a company need to be considered a major chain?

“Major chain” is a loose definition in the car wash industry, but for this ranking, we start with businesses that operate at least 5 locations. This helps separate multi-location operators from single-site or smaller local car wash businesses while still including growing regional chains.

Why are private equity firms investing in car washes?

Private equity firms are investing in car washes because the industry offers several attractive business advantages. Many modern car wash companies use membership-based models, which can create steady recurring revenue. Express car washes can also operate with relatively low labor needs, high vehicle throughput, and scalable systems across multiple locations.

Car wash businesses are also highly local, which gives investors opportunities to buy smaller operators, improve operations, rebrand locations, and grow through acquisitions or new development. For private equity firms, this combination of recurring revenue, fragmented ownership, and room for expansion makes car washes an appealing investment category.
