Wipe a wipeable interior lining with a damp cloth and a small amount of mild soap, then rinse the residue off with a second clean, damp cloth. For fabric compartments that have absorbed a spill, a gentle hand-wash with the same mild soap works, followed by thorough rinsing.
The step that actually prevents a musty smell is drying: leave the bag fully unzipped and open to air for at least a day before packing it away, since a bag sealed shut while still slightly damp is the most common cause of mildew appearing before the next trip.
What travelers ask
Why does my toiletry bag smell musty even though I wiped it clean?
A wipeable lining that's cleaned but not fully dried before being sealed shut in storage traps residual moisture, which is exactly the environment mold and mildew need. Leave the bag open and air-drying for a full day before packing it away.
