Leaving baking soda residue in the dryer after attempting to deodorize it with a baking soda and water solution is generally safe. Baking soda is a non-toxic and natural cleaning agent, so it won't pose any immediate health risks or hazards if a small amount remains in the dryer.
However, it's a good idea to remove any excess baking soda from the dryer before using it again. Baking soda may not be harmful, but having residue inside the dryer can be less than ideal for a couple of reasons:
Residue on clothes: If there is baking soda residue left in the dryer, it may transfer to your clothes during the next drying cycle. While it won't harm the clothes, it could leave white streaks or spots, which might be annoying.
Interference with dryer operation: Excessive baking soda residue may accumulate in parts of the dryer, such as the lint filter or vent, potentially affecting the dryer's performance or airflow.
To remove the remaining baking soda from the dryer:
Wipe down the interior: Use a damp cloth to wipe the interior of the dryer, removing any visible baking soda residue.
Vacuum the dryer drum: If there is still baking soda dust or residue in the drum, you can use a vacuum cleaner with a brush attachment to gently remove it.
Check the lint filter and vent: Inspect the lint filter and vent for any baking soda residue and clean them thoroughly to ensure proper airflow and prevent potential issues.
Run a test cycle: After cleaning, run a test cycle with old towels or clothes you don't mind getting in contact with any remaining baking soda. This can help remove any last traces of the residue.
Once you've taken these steps to remove the baking soda residue, your dryer should be ready to use normally again. Remember to always follow the manufacturer's instructions and guidelines for cleaning and maintaining your specific dryer model.
