Learn how to clean, dry, and store your banneton basket so mold never ruins your next sourdough bake. Simple steps for long-lasting proofing baskets.
Quick answer
To prevent mold, never wash your banneton with soap and water. Instead, brush out dry flour after each bake, let the basket air-dry completely, and store it in a dry, ventilated spot.
Why banneton baskets are mold-prone (and why you shouldn't wash them)
Banneton baskets are typically made from rattan or cane, which are porous natural materials. They absorb moisture from dough and humid air. If that moisture stays trapped, mold spores can grow deep in the fibers. Washing with water—especially soaking—weakens the basket and makes mold more likely. Instead, rely on dry cleaning methods and thorough drying.
The flour layer: friend or foe?
A thin, dry layer of flour is actually helpful—it helps release dough and contributes to the basket's non-stick surface. But excess flour can clump and hold moisture. The goal is to remove loose flour and dough bits without stripping the basket completely. If you see caked-on dough, let it dry fully, then brush it off gently.
When to deep-clean (and when to replace)
If your basket develops a sour smell or visible mold spots, you can try a deep clean: scrub with a dry brush, then expose it to sunlight for a few hours (UV helps kill mold). But if mold has penetrated deeply or the basket feels soft and mushy, it's safer to replace it. Prevention is always easier than rescue.
Step-by-step banneton care routine
- Remove excess dough and flour: After each bake, turn the basket upside down and tap out loose flour. Use a dry, stiff brush (like a dedicated pastry brush) to gently scrub the inside, focusing on crevices. Avoid using water or soap—even a damp cloth can introduce moisture. Checkpoint: the basket should look mostly clean, with only a fine, dry flour film remaining.
- Dry thoroughly: Set the basket in a well-ventilated area, ideally near a window or with a fan, for at least 24 hours. If humidity is high, place it in direct sunlight for a few hours (UV helps kill mold spores). Never stack or store it until bone dry. Checkpoint: the basket should feel completely dry to the touch, with no coolness or dampness.
- Store properly: Keep the basket in a dry, airy spot—not in a sealed plastic bag or a damp cupboard. A wire rack or open shelf is ideal. If you must stack baskets, place a paper towel between them to absorb any residual moisture. Checkpoint: avoid storing near the dishwasher, sink, or other moisture sources.
- Monitor for mold: Inspect your basket before each use. Look for fuzzy spots, dark patches, or a musty smell. If you spot early mold, brush it off outside and sun-dry the basket. If mold returns or the basket feels soft, replace it. Checkpoint: act at the first sign of mold—don't wait until it spreads.
