Removing The Mildew Smell From Your Comforter

To get rid of the musty mildew smell on your comforter, you just need to follow five simple steps. Make sure to prepare the materials beforehand and have the comforter that you’ll clean ready.


Step #1. Make the lemon paste

To make the paste, mix the lemon juice with table salt in a bowl. Continue adding the ingredients until you reach the consistency of a paste that is not too thin and is slightly thick.


Step #2. Apply the lemon paste to the comforter

Using the old soft-bristled toothbrush, apply the lemon paste onto the mildew stains on the comforter. Make sure to apply on every spot for a spotless and fresh comforter.

Afterward, lay a clean and big piece of cloth in an area where there is direct sunlight. Place the comforter over it and let the lemon paste dry.


Step #3. Brush the lemon paste off the comforter

Once the lemon paste is dry, grab the old toothbrush once again. Use it to brush off the paste from the comforter.

Remember to use gentle motions to avoid damaging the material. Do it thoroughly making sure no paste is left.


Step #4. Wash the comforter

The next thing you have to do for more effective cleaning is to run the comforter in a large capacity washing machine. Use warm water and a mild laundry detergent.

Add 1 cup of white vinegar to kill all the remaining mildew spores. It will also get rid of the musty smell on your comforter.

Preventing mildew

There is no better way to deal with mildew than to prevent it from developing. There are a lot of basic ways to do this.

Do your best to ensure that your comforter is always kept dry and clean. As much as possible, avoid eating and drinking near it so you can avoid spilling your favorite food and drinks into your comforter.

If a spill unfortunately happens, clean it up immediately. Then, wash the comforter and run it a dry cycle to get rid of all the moisture.

When storing your comforter, place it in a cool, dry place to avoid moisture that may cause the growth of mildew. Never store your comforter in a plastic bag.

Plastic bags do not allow air to penetrate inside promoting the development of mildew. If a breathable storage bag is not available, wrap your comforter in clean and dry cotton towels before storing.

You can also use any old cotton clothing. Cotton allows good airflow which is very effective in preventing mildew buildup.



Mildew, together with the other fungi, are truly such troublemakers. They are just not the type you would want to deal with especially in your home.

Now that the process of how to get mildew smell out of comforter has come to light, enjoying fresh-smelling bedding is nowhere out of reach.
