Sink Clogged Route Walkthrough — Moldwasher

This Moldwasher walkthrough page covers the clogged sink mission that blocks progress at 0% until the clog clears. This is one of the most searched stuck points—players spray water endlessly while progress never moves. Use the steps below alongside our Tools section when a mission requires equipment you have not yet unlocked.

Why the Sink Stays at 0%

The sink mission includes a mandatory clog removal step before normal cleaning registers. Water spray on the basin does nothing until the clog mechanic completes. If your progress bar shows 0% despite active spraying, you have not finished the clog step—not a bug.

Look for visual indicators around the drain, sponge, and pipe areas. The mission expects interaction with the clog target before sponge, basin, and edge cleaning counts toward completion.

Step-by-Step Sink Route

Locate the clog indicator near the drain—often requiring direct spray on a specific spot
Complete the clog removal until the game acknowledges clearance
Clean the sponge with appropriate spray mode
Wash the drain, basin interior, and outer edges
Sweep remaining mold from counter surrounding the sink
Verify 100% and check hidden drop counter before leaving

After clog clearance, the pressure washer handles all remaining targets normally. Precise stream helps with faucet edges and tight basin corners.

If Still Stuck

Press Tab to highlight remaining spots if progress stalls above 0% but below 100%. Switch between wide and precise spray for edge pixels. If nothing responds after clog completion, restart the mission—a rare launch-build issue reported on some configurations.

Compare your approach with the Tool Selector—sink missions use water only, so wrong-tool confusion usually means the clog step was skipped, not wrong equipment.
