Game Overview — Moldwasher
Moldwasher is a cozy arcade-style cleaning simulator developed by Rubel Games and published by Anshar Publishing. Released on Steam June 23, 2026, the game puts you in the role of Nigiri—a brave sushi hero—cleaning mold from fridges, kitchens, garages, sewers, and other surprisingly gross locations.
What Is Moldwasher?
Moldwasher combines the satisfaction of power-washing simulators with charming 2D pixel art and arcade pacing. You are tiny compared to the kitchen environments—a Honey I Shrunk the Kids perspective where flies tower over you and fridge shelves become sprawling levels. The tone balances gross-out humor with genuinely relaxing lo-fi audio and satisfying spray feedback.
Unlike narrative-heavy simulators, Moldwasher drops you directly into action. There is no story tutorial—just clean, earn, upgrade, and expand. The hub between missions serves as a customizable home where you play collected CDs, pull gachapon decorations, and display found stickers and toys.

Who Should Play Moldwasher?
