What it requires
Power Wash Pro unlocks when you pressure wash 350 items. It is a repeatable, progress-based achievement that counts every item you wash.
Best maps to build it
- Trailer Park: many stains on concrete, skirting and rims respond to the pressure washer.
- Zoo Enclosure: walls and vertical surfaces wash quickly.
- Any map with walls and fences works.
Method
- Wash every stained wall, fence and skirting as you complete each job.
- Turn on highlight effects so faint stains are visible.
- Replay wash-heavy levels to keep the counter moving.
