Run a cleaning cycle with a dryer cleaning product or vinegar to eliminate odors. Ensure the drum is empty, and follow the product instructions or mix a cup of vinegar with a load of towels. Run on the highest heat setting for 30 minutes.
Thoroughly clean the lint trap and vent. Remove lint from the trap after every load and clean the venting system at least once a year to prevent buildup.
Inspect for mold or mildew. If present, clean the drum with a mixture of water and baking soda. If the odor persists, consider replacing the drum seal or contacting a professional.
