How to remove mustard stains before the yellow sets

Step by step: how to remove mustard stains before the yellow sets

Safety first. Never mix hydrogen peroxide or vinegar with chlorine bleach. If you use bleach in the wash, rinse the fabric well first so no vinegar or peroxide is left in it.

1. 1

   Scrape, do not wipe

   Lift the mustard off with the edge of a spoon, a fork or a dull knife. Wiping with a napkin pushes the yellow paste sideways and into the weave, so the stain doubles in size.

2. 2

   Flush cold water through the back

   Turn the garment inside out and hold the stain under a cold tap for a minute. Water from the back pushes mustard out of the fibers instead of further in. Avoid hot water until the color is gone.

3. 3

   Work in detergent with a few drops of vinegar

   Mix a little light-duty liquid detergent or dish soap with a few drops of white vinegar, work it into the stain with a soft toothbrush, and rinse well. The soap lifts the paste, and the mild acid keeps the turmeric yellow instead of turning it red.

4. 4

   Pretreat with an enzyme detergent

   Pour a liquid laundry detergent that contains enzymes onto the stain, rub the fabric together gently, and leave it 5 to 10 minutes. The yellow should look noticeably paler before you move on.

5. 5

   Dab hydrogen peroxide on leftover yellow

   On white or colorfast fabric, test 3% hydrogen peroxide on an inside seam first, then dab it onto the stain with a white cloth. Leave it about 10 minutes and rinse. Skip this on colors that fail the test.

6. 6

   Wash in the warmest water the label allows

   Wash with detergent. Add chlorine bleach for bleach-safe whites, or a color-safe stain remover for colors and for whites that contain spandex.

7. 7

   Air dry in sunlight and inspect

   Hang the item in direct sun to dry. The pigment in turmeric fades in light, so the sun often removes a faint shadow. If yellow remains, repeat the pretreat before the item goes in the dryer.

Why is mustard such a hard stain?

Mustard is hard because its bright yellow comes from turmeric, a dye that is not water-soluble and bonds quickly to cotton. The rest of the paste, ground mustard seed, vinegar and water, washes out easily; the dye is what stays.

Tide calls mustard one of the most stubborn stains because of its high turmeric content and says to act before it sets. Clorox warns that the turmeric in mustard is a yellow dye that can become permanent, and recommends an enzyme detergent and washing right away. Consumer Reports adds that curcumin, the turmeric pigment, is very sensitive to sunlight, which is why sun drying helps.

Turmeric turns reddish when it meets alkaline cleaners like baking soda or some soaps. That is not a new stain; it turns yellow again with a little vinegar. Our turmeric stain guide covers the chemistry in more detail.

Yellow, Dijon and brown mustard: which stains worst?

Classic yellow mustard stains worst because it is colored with turmeric; Dijon and many spicy brown mustards contain little or no turmeric and come out more easily.

Check the label of the jar: if turmeric is listed, treat it as a dye stain and do not let it dry.

How to remove dried or set-in mustard stains

Dried mustard usually needs a long pretreat and a second wash, but it can still come out. Tide’s set-in method is to scrape off the excess, soak the stain in cold water, spread liquid detergent over it, wait 10 minutes, rinse with warm water, and wash as usual.

OxiClean says its stain remover spray can be left on for at least 5 minutes or up to a week before washing, but no longer than 5 minutes on fabrics prone to color change. The University of Georgia Extension finishes with 3% hydrogen peroxide if a stain remains and stresses treating mustard immediately.

Mustard on dry clean only clothes, leather, carpet and upholstery

When you cannot wash the item, remove as much as possible and keep moisture to a minimum.

• Dry clean only, silk and wool: scrape, blot with a damp white cloth, and take it to a dry cleaner the same day, naming the stain.
• Leather: wipe with the suds of a mild soap on a sponge, then a damp cloth, dry it, and apply leather conditioner.
• Carpet: scrape, apply a carpet-safe oxygen cleaner for 1 to 5 minutes, and blot with a white towel without letting it dry. See how to remove stains from carpet.
• Upholstery: blot with a solution of 1/4 teaspoon dish soap in 1 cup of warm water, then with plain water, and let sunlight reach the spot if possible.

Mistakes to avoid

• Wiping mustard with a napkin, which spreads the dye.
• Rinsing with hot water before the yellow is gone.
• Scrubbing with baking soda or ammonia-based cleaners, which turn turmeric red and can push it deeper.
• Putting the item in the dryer with a faint yellow left, which can make it permanent.
• Waiting until laundry day; mustard sets fast.
