PowerWash Simulator has evolved from a niche relaxation title into a massive collection of cleaning tasks, especially with the influx of high-profile DLCs. As of early 2026, the achievement list has expanded significantly, now totaling over 100 individual challenges. Earning every trophy requires a blend of patience, attention to detail, and a specific order of operations in both the base game and its various expansions. This breakdown covers the essential strategies for clearing the board.

The Foundation: Career Progression and Stars

Most players begin their journey in Career Mode. This is where the bulk of the progression achievements reside. The star system is the primary metric of success, with one star awarded for every 20% of a job completed.

  • Starting Out: This triggers early, requiring only 5 stars. It serves as an introduction to the rewarding "ding" sound of a finished task.
  • Raking it In & Big Business: These milestones mark the 50 and 100-star thresholds. By the time 100 stars are achieved, the complexity of the maps increases significantly.
  • Super Star: Reaching 150 stars represents a significant time investment. To hit this, nearly all base game career missions must be pushed toward 100% completion.
  • As It Was Foretold...: This is awarded upon completing the final mission of the Career Mode. It remains one of the more satisfying completions in the simulator genre.

Equipment and Customization Milestones

Success in the later stages of the game is heavily dependent on the gear used. Several achievements are tied directly to purchasing power washers and their respective attachments from the in-game shop.

The Prime Vista Series

The Prime Vista series represents the core progression of your cleaning power.

  • Fully Equipped: Requires owning the Prime Vista 1500 and three of its attachments. This is the entry-level kit and is usually the first gear-related achievement unlocked.
  • Heavy Hitter: This steps up to the Prime Vista 3000 and five attachments. The cost increase is noticeable, but the cleaning efficiency makes it worth the investment.
  • Unlimited Powerwash: Owning the Prime Vista Pro and all six attachments is the ultimate goal. The Prime Vista Pro is the most powerful tool in the base game, essential for large-scale structures like the Mayor's Mansion.

Aesthetics and Logistics

  • Fashionista: This is a simple but often overlooked achievement. It requires equipping a new outfit, gloves, and a washer modification simultaneously. Modifications can be applied in the loadout menu by selecting the bottom right corner of the washer icon.
  • Soap Connoisseur: To unlock this, one must own all types of cleaning liquids (glass, metal, plastic, stone, wood, and multi-purpose) at the same time. While soaps are rarely necessary for a 100% completion run, they are required for this specific trophy.

Map-Specific Order of Operations

Many PowerWash Simulator achievements are "missable" in the sense that they require you to clean specific objects first or last. If these are missed during the initial Career run, they can be revisited in Free Play.

  • Pave the Way: In the Detached House, the pathway, driveway, and driveway edges must be completed before anything else. It is easy to accidentally clip the walls of the house, so aiming away from the building is suggested.
  • First Steps: In the Back Garden, the 12 stepping stones leading to the patio must be the first items finished.
  • I Can See Clearly Now: During the Fire Truck job, the windows, windscreen, and wing mirrors must be the priority. Using a narrower nozzle helps prevent accidental cleaning of the truck's body.
  • Lantern Hunter: The Treehouse map contains 12 lanterns. These must be the first items completed. They are spread across several levels, including the spiral stairs and the middle deck.
  • Sole Task: In the Shoe House mission, the sole of the shoe must be the very last thing cleaned. This is a test of restraint, as the sole is a large, tempting surface.
  • Delaying the Inevitable: In the Washroom, the toilets, seats, and lids must be cleaned last. It is recommended to work from the walls and floors inward.

Hidden Interactions and Easter Eggs

Some of the most creative achievements involve interacting with the environment in ways that have nothing to do with cleaning.

  • Watermelon Shot: At the Skatepark, a ball must be pushed out of the bowl using the water pressure. A high-pressure red nozzle is the most effective tool here.
  • Impeccable Balance: Stand on the Penny Farthing (the large-wheeled bicycle) for 10 seconds. This requires finding the bicycle and simply jumping onto the seat.
  • Gnome Sweet Gnome: In the Temple, a gnome must be placed on the tower roof once the job is complete. This requires carrying the gnome or using water pressure to nudge it into position before the final 100% notification triggers.
  • Stegoscore: In the Playground, a football must be rolled up the stegosaurus slide. This is notoriously finicky and requires steady, low-pressure streams to guide the ball.

Restricted Nozzle Challenges

These achievements test the player's patience by restricting them to specific nozzles that may not be optimal for the job.

  • Powerful Pressure Purist: Complete the entire Van cleaning job using only the red (0-degree) nozzle. This nozzle has the smallest surface area, making the task tedious but straightforward.
  • Delicate Excavation: Clean the Ancient Monument using only the white (40-degree) nozzle. The white nozzle has lower pressure, which can make removing stubborn grime from the stone challenging.
  • Good Dings to Come: Clean 95% of any job without completing any individual tasks. This is best achieved on a map with many large, distinct parts. The goal is to spray everything until it is almost clean, but stop before the task completion "ding" occurs.

The Challenge Mode: Going for Gold

For many, the most difficult achievements in the game are Going for Gold and Gold Standard, which require earning one and five gold medals in Challenge Mode, respectively. Challenge Mode strips away the relaxation and adds time or water limits.

  • Time Challenges: These are generally considered easier than water challenges. The strategy is to use the most powerful washer available and ignore perfection. A 99.9% clean often counts as a full completion in this mode.
  • Water Challenges: These require extreme precision. Using the soap nozzle is often more water-efficient than standard nozzles, as it covers a wide area with very little liquid usage.

Navigating the Major DLC Packs

As of 2026, the achievement list has been bolstered by several massive DLC expansions. Each comes with its own set of thematic trophies.

Warhammer 40,000 Special Pack

Cleaning the grim dark future of the 41st millennium offers some of the most complex mechanical models in the game.

  • Cadia Stands!: On the Rogal Dorn Battle Tank, the stowed shovel must be cleaned first.
  • Eternal Service: Complete the Redemptor Dreadnought. This is a massive task with intricate mechanical parts.
  • Degrees of Redemption: This is the hardest DLC-specific nozzle challenge: cleaning the Redemptor Dreadnought using only the yellow nozzle. Given the size of the Dreadnought, this requires significant time.
  • Sanguinius Would Be Proud: Complete the Thunderhawk, one of the largest vehicles in the game.

SpongeBob SquarePants Special Pack

This underwater-themed pack features unique physics and vibrant environments.

  • Naughty Nautical Neighbors: Complete the Conch Street job (cleaning the houses of SpongeBob, Patrick, and Squidward).
  • Bucket Sweet Bucket: In the Krusty Krab job, the Chum Bucket must be finished first. This requires walking across the street to the rival restaurant before touching the Krusty Krab.
  • It’s Not a Boulder, It’s a Rock!: In the Conch Street job, Patrick’s rock, the rock hinge, and the rock underside must be the last items cleaned.

Back to the Future Special Pack

These missions take players to Hill Valley to clean iconic locations and vehicles.

  • Great Scott!: Complete Doc Brown's Van.
  • 88 Miles Per Hour!: Watch the Time Machine reappear. This is a scripted event that occurs during the mission progression.
  • This is What Makes Time Travel Possible: On the Time Train, the flux capacitor and its particle colliders must be the first items cleaned.

Shrek Special Pack

  • Get Out of My Swamp!: Awarded for completing Shrek’s Swamp.
  • Welcome to Duloc: In the Duloc job, the player must interact with the information stand lever.
  • Look at Me Shrek, I’m Trotting: In the Fairy Godmother’s Potion Factory, run on the running wheel for 20 seconds. This is one of the more humorous physical interactions in the game.

Alice’s Adventures in Wonderland

  • Down the Rabbit-Hole: Complete the Entrance Hall.
  • A Mad Tea-Party: Complete the famous tea party map.
  • Like a Tea Tray in the Sky: Balance on the strawberry on the topmost cake of the cake stand for 10 seconds. This is a platforming challenge that requires careful jumping.

Strategy for 100% Completion

To maximize efficiency when hunting PowerWash Simulator achievements, players should cross-reference the achievement list before starting a new Career mission. Many of the "First/Last" achievements can be easily missed, requiring a full replay in Free Play.

Using the Tab key (or the equivalent button on a controller) to highlight dirt is vital. In the final percentages of a job, small flecks of dirt can be invisible to the naked eye. The "Task List" in the menu is also helpful; clicking on an incomplete item will cause it to flash in the environment, making it much easier to track down that last 0.1%.

Co-op play can also assist with completion. While most achievements can be earned as a client in someone else's game, the host is the one who primarily progresses through the Career milestones. If you are struggling with a particularly large map, such as the Great Pyramid or the Warhammer vehicles, bringing in a friend can cut the cleaning time in half without voiding most achievement requirements.

Ultimately, the achievement list in PowerWash Simulator is a marathon, not a sprint. It rewards thoroughness and a methodical approach to cleaning, reflecting the core philosophy of the game itself.
