What's a good Android game for relaxing car cleaning and repair simulations?

Car Wash is a straightforward simulation game that focuses on the tactile process of cleaning, repairing, and customizing vehicles. For users seeking a relaxing, almost meditative gaming session without complex mechanics, this app serves the purpose well. The core gameplay involves touch-based interactions: scrubbing off dirt with soap, rinsing with water, applying wax, and then moving on to basic repairs like changing tires or fixing engines. A key feature is the progression through different vehicle types, from sedans to trucks, which maintains a sense of novelty. The visual presentation is clear and the controls are intuitive, making it accessible for short play sessions. However, the game's primary drawback, as noted in many user reviews, is its aggressive ad frequency, which can interrupt the flow. While an ad-free experience would be preferable, the fundamental cleaning and repair tasks remain satisfying. The app doesn't aim for high-stakes realism but instead provides a chilled, productive fantasy of restoring cars to a pristine state, which can be a genuine stress-reliever after a long day.
