Mustard is one of our most popular condiments, yet one of the most annoying stains to remove, especially due to the yellow dye of turmeric. Because it sets so quickly, dealing with it right away is absolutely necessary. If the stain is dried, your only chance may be soaking and a color safe oxygen bleach.

What You Need to Remove Mustard Stains

Gather these household tools to remove your mustard stains:

  • Dull knife or spoon
  • Liquid laundry detergent
  • Stain remover stick, gel or spray
  • Color-safe oxy bleach

Removing Fresh Mustard Stains on Washable Fibers

  1. Remove as much mustard as you can. Use a dull knife or a spoon to gently scrape away as much mustard as possible. Be careful not to scrape so forcefully that you damage the fibers of the clothing. Don't skip this step or you'll risk getting mustard on other parts of the clothing and creating a new stain.
  2. Rinse in cold water. Rinse through the back of the stain to force the mustard back out of the fabric. Heat is going to set the mustard, so cold water is a must. 
  3. Add liquid laundry detergent. Rub liquid laundry detergent onto the mustard stain and allow the clothing to sit for up to 10 minutes. Rinse the stained area thoroughly. Repeat this step until no mustard stain is left. If you don't have liquid laundry detergent, try a dish soap as a backup. Laundry detergent is preferred, especially since this is a tough stain.
  4. Add a stain remover. Following the directions, apply a stain remover to the mustard stain. A gel or liquid stain remover is going to soak in better than a stick. Wash normally with liquid laundry detergent. Before drying the clothing, check to make sure that all of the mustard has been removed. If any hint remains, repeat the steps above. It likely won't all disappear on the first try and most of the time you'll have to repeat these steps again.

    Removing Fresh Mustard Stains on Non-washable Fibers

    Follow these steps for acetate, triacetate, rayon, silk, wool, and burlap. You'll need some additional tools to clean non-washable fibers.

    1. Lift off any excess mustard with a dull knife or spoon.
    2. Apply a stain remover to loosen the residue with a cleaner like Afta Cleaning Fluid.
    3. If the fabric is strong, use a brush (a new toothbrush works well) to make light strokes on the fabric (tamping) and then blot the excess with an absorbent pad. You can also use a dull tool to scrape the caked-on stain.
    4. Flush with the dry-cleaning solvent.
    5. If stain remains, use a sponge or pad dampened with water and make light strokes, moving outward from the center of the stain. Then apply a wet sponge with few drops of white vinegar.
    6. Tamp again to loosen stain and flush with water.
    7. If the stain is still visible, moisten the area with 3% hydrogen peroxide plus a drop of ammonia (except on silk and wool). Do not bleach longer than 15 minutes, then flush with water let it dry.

    Dried Mustard Stains

    Dried stains need to be soaked in cool water with a color safe oxygenated bleach for 30 minutes to as much as an hour before washing normally. Dried mustard stains are one of the toughest stains on the planet to remove and there's a very good chance that you will need to soak the item several times for best results. You can alternate with the steps above for fresh stains. This stain takes a lot of work to fully remove, but it can be done with patience and persistence
