Express Car Wash Simulator is a first-person simulator where you build and manage your own car wash business from the ground up. You'll clean dirty cars with handy tools, thick foam, and colorful detergents, while also providing additional services like driving, wheel care, and custom sticker application. The core gameplay revolves around increasing your business's reputation by satisfying customer needs, unlocking higher service levels and more profitable orders. Beyond washing, you can upgrade your store by installing slot machines and vending machines to enhance the customer experience and create a welcoming atmosphere.
