PowerWash Simulator

This is earned roughly a third of the way through the game and will be achieved with normal progression. It will likely unlock for you after getting 5 stars on the "Shoe House" level. Also on that level clean the sole (bottom part of the shoe last to earn another achievement)

Tips:
1. Stars are earned through objectives on any given maps, the more things fully cleaned the more stars you get, for a level to be "completed" you are required to get 5/5 stars and clean everything.

2. Buy more powerful washers as they become available to you attachments like range extenders can be helpful too as later missions have more verticality.

3. Focus specific map areas as you go trying to fully clean one object before moving to the next as this will save you time hunting mixed spots later.

4. Spam your dirt reveal ability as it has no cooldown and will save you tons of time.
