How to Get Rid of Mildew on Sheets

Quck answer

Mildew on sheets can be unsightly and unpleasant. To remove mildew from sheets, follow these steps:

1. Start by washing the sheets in hot water with a regular laundry detergent.

2. Add a cup of white vinegar to the wash cycle to help kill any remaining mildew spores.

3. After washing, hang the sheets outside in the sun to dry. Sunlight can help further kill mildew and remove any remaining stains.

4. If the mildew stains persist, create a paste using equal parts hydrogen peroxide and baking soda. Apply the paste to the stained areas and let it sit for 30 minutes before washing again.

5. Repeat the process until the mildew is completely gone.


If sheets are left damp for a long time, they will eventually develop mildew, especially in warm weather. Mildew not only causes a bad smell on the sheets, but it can also leave stains. Simply washing the sheets with detergent is usually not enough to remove the mildew odor or stains. It is best to address mildewed sheets as soon as you notice them, but even if you don’t notice right away, there is still a chance to remove the mildew.

White Sheets

Step 1

Place the mildewed sheets in a sink or washing machine and fill it with enough water to cover the sheets. Add chlorine laundry bleach at a ratio of 2 tablespoons per quart of water, following the advice from the Michigan State University Extension.

Step 2

Let the sheets soak in the bleach and water solution for 15 minutes. Then, wash the sheets in hot water using your regular laundry detergent.

Step 3

Hang the sheets outdoors in direct sunlight to dry. If there are any remaining mildew stains after drying, repeat the soaking and washing process.

Colored Sheets

Step 1

Place the mildewed sheets in a sink or on a table. In a bucket, mix 2 tablespoons of an oxygen bleaching agent or a color-safe bleach with sodium perborate with 1 pint of hot water.

Step 2

Put on rubber gloves and use a sponge dipped in the solution to wipe over the mildew stains on the sheets. Let it sit for at least 30 minutes.

Step 3

Rinse the sheets with warm water and wash them with your regular detergent. Then, hang them to dry or use a clothes dryer.
