Good Dings to Come
────────────────
"Clean 95% of any job without completing any tasks"

This will be a slow process. I completed it on the Van job using the red nozzle due to its small but powerful nature. A good reference point for the tasks is to bring the completion bar to around the bottle that's next to the material. If you get every task to this point, then slowly work down larger parts so that you have more leeway.
────────────────────────────────────────────────
Gnome Sweet Gnome

The gnome can be on its side, as long as it's on top. Start with the tower roof first to make sure you restart early on if you need to.
