Tidal Wave Auto Spa, a car wash chain, completed the acquisition of W4 Express Wash. Financial terms were not disclosed. “We are thrilled to welcome the W4 washes to the Tidal Wave family. This acquisition is aligned with our footprint, values, and goal to be the best carwash in the industry. Not only does Tidal Wave gain ten open locations, but also a robust pipeline of greenfield development that we will fold into our aggressive focus on greenfield store development. We plan to provide tremendous personal and career growth for our new team members and allow W4 wash plan members the opportunity to experience the Tidal Wave difference,” Scott Blackstock, Tidal Wave Auto Spa CEO and Founder.
