Why Does an Old Blanket Smell So Bad and How to Fix It

Old blankets can develop a variety of unpleasant odors, which can be quite off-putting. It's important to understand the root causes of the smell so you can effectively address the issue.

Common Causes of an Old Blanket's Bad Smell

Blankets, especially older ones, can accumulate a range of substances over time that lead to foul odors. Here are the primary reasons:

Accumulation of Dirt and Oils

Over time, blankets collect dust, sweat, and body oils. These substances can lead to a musty or sour smell. As they accumulate, the fabric itself becomes more prone to retaining these odors.

Mold and Mildew

If a blanket has been stored in a damp environment, it can develop mold or mildew. These fungi produce a strong, unpleasant odor. Proper ventilation and dry storage can help prevent this.

Bacteria

Bacteria can thrive in warm, moist environments, particularly if the blanket is not regularly washed. Bacteria break down organic materials, leading to odors. Regular washing can help prevent bacterial growth.

Fabric Degradation

Older fabrics, especially synthetic materials, can degrade over time, leading to chemical changes in the fibers. These changes can cause odors. Regular washing and proper storage can help mitigate this issue.

Effective Odor Solutions

There are several methods to reduce and eliminate the unpleasant smells in your old blankets. Here are some effective strategies:

Regular Washing

Regular washing is crucial to keeping blankets fresh. Ensure they have enough space to move freely in the washing machine. Pay attention to the care label and use the appropriate cycle. Always rinse thoroughly to remove any detergent residues that could cause staining or other issues.

Proper Storage

Store blankets in dry, well-ventilated areas. Avoid storing them in poorly ventilated attics or basements where they can absorb mold and mildew. Regular airing out in a dry place can also help prevent odors.

Using Baking Soda

Baking soda is an excellent natural odor-fighting agent. To use it:

Add about 1/2 cup of baking soda to the washer when it's filling with water. Let it dissolve before adding the blanket. Let the washer agitate for a few minutes, then turn it off and let it soak for 30-60 minutes. Wash the blanket on its own, giving it plenty of room to move. Rinse twice to ensure all baking soda is removed. For HE/front-loading machines, add the baking soda directly into the detergent cup.

Using Vinegar

Vinegar is another natural odor remover. To use it:

Use 1/4 to 1/2 cup of white vinegar in the rinse cycle of your washer. If you have a fabric softener dispenser, add the vinegar there. Otherwise, you can use an old Downy ball or manually pour it in during the rinse cycle.

Conclusion

By understanding the common causes of an old blanket's bad smell and employing effective odor-fighting techniques, you can restore your blankets to their former glory. Regular washing, proper storage, and the use of natural odor removers like baking soda and vinegar can help keep your blankets fresh and pleasant-smelling for years to come.
