Car Wash Simulator (Demo) Update History: Full Patch Notes

Early Access Launch & Initial Patches

The journey of Car Wash Simulator (Demo) began with its free release on Steam. The initial launch version (1.0.0) introduced the core gameplay loop, allowing players to clean three unique vehicles using high-pressure foam and detailed tools. The developers, Majestic Twelve, quickly followed up with a series of stability patches based on community feedback.

The first major patch addressed several launch-day issues. If you are new to the game, check out our beginner guide for the basics.

Patch 1.0.1: Stability and UI Fixes

Released shortly after launch, this patch focused on improving the overall user experience and fixing critical bugs.

1. Crash Fixes

   Resolved a crash that occurred when switching between the pressure washer and the foam cannon too quickly. Also fixed a rare crash when entering the garage area.

2. UI Improvements

   The tutorial prompt for the "Wash Timer" now correctly disappears after the first use. Adjusted the font size on the results screen for better readability.

3. Vehicle Adjustments

   Slightly reduced the dirt accumulation rate on the "Classic Sedan" to make the cleaning process more manageable for new players.

Patch 1.0.3: New Features and Content

The most substantial update to the Demo brought new features and expanded the core experience. This patch introduced the long-awaited "Test Drive" area improvements.

Key additions in this patch:

• Test Drive Area Expansion: The parking lot test drive area has been expanded with new obstacles and a small slalom course to test your cleaned vehicle's handling.

Patch 1.0.4: Quality of Life Update

The final major patch for the Demo focused on quality-of-life improvements based on extensive player feedback.

• Quick Select Wheel: Players can now press a number key (1-4) to quickly select a wheel for cleaning, rather than manually aiming at each tire.
• Soap Indicator: A new on-screen indicator now shows the remaining soap level in the foam cannon, preventing unexpected interruptions.
• Water Pressure Gauge: The pressure washer now features a visual pressure gauge, allowing for better control when removing tough dirt.
• General Stability: Multiple crash fixes related to the game's save system and the transition from the garage to the test drive area.

Future Updates and Full Release

The development team has confirmed that the Demo will not receive further major updates as they focus on the full release of Car Wash Simulator. The full game promises a career mode, more vehicles, and a wider range of customization options.

What to expect in the full game:

• A full story campaign with a progression system.
