How to Remove Mildew from a Futon

Quck answer

Mildew can be a common problem for futons, but there are several steps you can take to eliminate it. First, remove the futon cover and wash it in hot water with detergent. Next, vacuum the futon thoroughly to remove any loose mold spores. Then, mix equal parts of water and vinegar in a spray bottle and spritz the affected areas. Let it sit for a few hours, then scrub the mildew with a brush and wipe it clean with a damp cloth. Finally, place the futon in a well-ventilated area to dry completely. Regularly airing out the futon and using a dehumidifier can also help prevent future mildew growth.


You can identify the musty odor and the visible dark, thin trail of mildew. You are shocked to see that it has attached itself to your favorite futon, the one you planned to move from the damp basement to your reading room. There is no need to panic. The simple fungus known as mildew can be eliminated from almost any surface, as long as you are willing to put in some effort.

Prepare the Fabric for Treatment

Step 1

Take the futon outside and use a broom to brush off any visible mold from its surface. You want to prevent the mildew spores from spreading around the house.

Step 2

Go a step further by vacuuming the futon cushion. If your vacuum has a bag, remove and dispose of it immediately. If you do this outside, you further reduce the risk of spreading spores in your home.

Step 3

Mildew is affected by sunlight and fresh air, so allow your futon to spend plenty of time outside to absorb both.

Step 4

Check if the futon fabric can be washed. If it can, proceed to the next step. If not, you will need to have it dry cleaned.

Clean the Fabric

Step 1

Before attempting any cleaning methods, check if the fabric is colorfast.

Step 2

If you have confirmed that the futon is colorfast, lightly sponge the affected area with a mixture of soap and water. Use as little water as possible to avoid soaking the futon pad.

Step 3

If any stains remain after washing the futon with soapy water, clean them with a mixture of lemon juice and salt. Spread the futon out to allow the fabric to bleach in the sun.

Step 4

If stubborn mold persists, try using a chlorine bleach solution. Mix 1/4 tsp. of bleach with 1 cup of water, dip a clean cloth into the mixture, and apply it lightly to the fabric. It is important to test this cleaning solution in an inconspicuous area first to check if it is colorfast.

Step 5

Make sure to wipe away any solution you have used with a clean cloth. Allow the futon to dry completely to prevent the growth of more mildew.

When to Seek Help

Step 1

If the mildew is particularly stubborn or has penetrated into the padding, it may be necessary to have the futon professionally dry cleaned.

Step 2

Inform the dry cleaner about the mildew problem so that they can properly dry and fumigate the futon cushion.

Step 3

Remember to keep your newly cleaned futon in a dry room with sufficient air circulation to protect it.
