Powerwash Simulator dude. It’s almost like a reverse coloring book. You start off with a map or object completely covered in grime and take your time cleaning it in small sections. Some of the levels are truly incredible, like the skate park, treehouse, and paint ball arena. I like to put on some chill music, lay back, relax and start washing. They just added some Back to the future DLC which is gonna be awesome 😎👍
