How to Deep Clean Your Shark Dust Cup (Remove Mold & Odor)

Simply emptying the dust cup is not enough. Over time, fine dust, pet dander, and humidity create a perfect environment for mold and bacteria growth. If your vacuum smells bad even with clean filters, the dust cup itself is the culprit.

Here is how to perform a deep clean.

1. Disassemble Completely

Most Shark dust cups have removable parts:

• The Main Bin: The transparent plastic container.
• The Lid/Shroud: Often has a cyclone separator inside.
• The Gasket/Seal: A rubber ring that seals against the vacuum.

Take everything apart. Check for trapped debris in any crevices.

2. Rinse with Hot Water

• Hold all plastic parts under hot running water.
• Use a soft brush (like an old toothbrush) to scrub inside corners.
• Pay special attention to the cyclone “fins” where dust accumulates.

3. Sanitize with Vinegar Solution

Vinegar is a natural antibacterial and deodorizer.

1. Fill a basin with 50% white vinegar, 50% hot water.
2. Submerge the dust cup parts for 30 minutes.
3. Scrub again with the soft brush.
4. Rinse thoroughly with clean water.

4. For Stubborn Mold: Use Diluted Bleach

If you see visible black or green mold:

1. Mix 1 tablespoon of bleach in 1 gallon of water.
2. Soak the affected parts for 15 minutes only (bleach can weaken plastic).
3. Rinse thoroughly at least 3 times.

5. Dry Completely

CRITICAL: Do not reassemble until all parts are 100% dry.

• Air dry for 24 hours.
• Place parts in a sunny window if possible (UV light kills remaining bacteria).

Preventing Future Mold

Habit	Impact
Empty after every use	Prevents moisture buildup
Store with lid open	Allows airflow
Deep clean monthly	Stops mold before it starts
Never vacuum wet debris	Main cause of mold growth

TIP: If the smell persists even after a deep clean, the odor may have absorbed into the plastic pores. Consider replacing the dust cup assembly (typically $15-$25 on Amazon).
