How to Clean a Sleeping Bag (Down or Synthetic)

Whether it’s from summer camp, a weekend backpacking trip, or long-term storage, your sleeping bag collects dirt, body oils, and grime that reduce its warmth and comfort. To keep it performing like new, proper care is essential.

Here’s a complete guide on cleaning sleeping bags—and why Bibbentuckers is the safest choice when you want professional results.

Sleeping bags are technical gear, and most manufacturers include specific instructions. The most important rule:

• Never dry clean a sleeping bag — dry cleaning chemicals strip protective oils from down, clog breathable fabrics, and may void the warranty.

If you’re unsure, Bibbentuckers can handle cleaning without risk to your bag’s insulation or shell fabric.

For small stains:

• Use a mild, non-detergent soap or down-specific cleaner.
• Push the down or synthetic fill away from the stain before treating.
• Gently scrub with a soft cloth, then rinse with clean water.
• Make sure the spot is completely dry before storing.

If the care tag allows machine washing:

1. Use a front-loading commercial washer (top-load agitators can tear fabric).
2. Choose a down-safe soap to protect insulation.
3. Soak heavily soiled areas with diluted cleaner before starting.
4. Wash cold, delicate cycle with an extra rinse to remove residue.
5. Carefully lift the bag when wet—it will be heavy and fragile.

For delicate or older bags:

• Fill a bathtub or large basin with cool water.
• Add down soap or mild cleaner.
• Gently knead the bag to work out dirt and oils.
• Rinse thoroughly until water runs clear.
• Gently press out excess water without wringing.

Drying is the most time-intensive step—but the most critical.

• Use a large commercial dryer on medium heat.
• Periodically stop and break up clumps of insulation by hand.
• Add clean tennis balls or dryer balls to help restore loft.
• Ensure the bag is 100% dry before storage to prevent mildew.

Over time, a sleeping bag’s durable water repellent (DWR) finish wears off.

• Heat from the dryer can reactivate the coating.
• If water no longer beads on the surface, apply a DWR treatment designed for technical fabrics.
