How to Get Tomato Sauce Stains Out of Clothes

Q: Does hot water set a tomato stain?

Starting with hot water is a poor first move. The American Cleaning Institute’s method begins with a cold-water flush from the back of the stain. Once you have treated and washed the item, you can use the water temperature on the care label, but only put the garment in a hot dryer after the stain is gone.

Scrape off the extra sauce, then run cold water through the back of the stain as soon as you can. The American Cleaning Institute says to work liquid laundry detergent into the spot from the outside in, use a mild bleaching agent only on white or colorfast-tested fabric, pretreat with a stain remover, and wash as usual — but not to put the garment in the dryer until the mark is gone.

Tomato and pasta-sauce stains are a mix of dye from the tomato and, often, oil from the sauce or cheese. That is why a quick rinse from the back of the fabric matters, and why a later trip through a hot dryer can lock in what is left. The steps below follow ACI’s tomato-sauce and spaghetti-dinner guidance, with a separate note for greasy pasta or pizza stains. Check the care label first, and pretest any bleach or stain remover on a hidden seam. For other stains, see our laundry stain removal chart.

Act quickly, and work from the back of the stain

Remove as much sauce as you can with a spoon or a dull knife. Do not rub it deeper into the weave. If the fabric is washable, ACI says to run cold water through the back of the stain as quickly as possible, so the sauce is forced back out of the fabric. Running water through the front can push the stain farther in. ACI’s ketchup advice is the same idea: flush from the backside, and avoid dabbing in a way that spreads the mark.

Start with cold water. ACI’s pizza-stain notes say to start with cold water so a tomato-sauce stain is less likely to set. Save hot water for the wash later, and only if the care label allows it and the red mark has already lifted.

Step-by-step for washable clothes

1. Work in liquid laundry detergent

Rub a liquid laundry detergent into the stained area. ACI says to work it in gently in a circular motion, beginning on the outside of the stain and moving inward. That helps you avoid spreading a ring. Give the detergent a few minutes to sit, then rinse.

2. Use a mild bleaching agent only if the fabric can take it

If the garment is white, or you have tested it for colorfastness, ACI says you can apply a mild bleaching agent. The options it lists are hydrogen peroxide or white vinegar, applied with a sponge, and lemon juice on white fabrics. Rinse well. Repeat the detergent step and this mild bleach step until the stain no longer shows. Hold the area up to the light to be sure it is gone, which is ACI’s check before you move on.

Skip this step on untested dark or bright colors. Do not mix vinegar or lemon juice with chlorine bleach. If you later use chlorine bleach in the wash, rinse the fabric thoroughly first.

3. Pretreat with a stain remover, then wash

Apply a stain-remover stick, gel, or spray and let it sit for at least five minutes, as ACI directs. Then wash with detergent, following the care label. Before anything goes in the dryer, look at the stain again. ACI warns that stains that are dried will often be permanent.

4. If the stain remains, soak and treat again

If you can still see the mark, ACI says to rub detergent into it, soak the item in warm water for 30 minutes, and rinse well. If it is still stubborn, apply stain remover again and launder according to the product directions. You can also add a bleach that is safe for the fabric — chlorine bleach only where the label allows it, or a color-safe oxygen bleach on many washable colors. For how oxygen bleach is used with detergent, see can you use OxiClean with laundry detergent.

Air-dry and check once more. Repeat the pretreatment and wash if needed. Do not use the dryer until the stain is gone.

Pasta sauce, cheese, and other greasy tomato stains

A pasta-dinner stain is often tomato plus oil. Treat the red dye with the cold-water method above. If a greasy film remains, treat that as an oil stain as well. ACI’s pizza-stain advice for cheese grease is to blot first, rinse with cold water, add a little dish soap, pretreat with a stain remover, and let it sit before you launder. Check that the stain is gone before the dryer. Prewash stain removers, ACI’s laundry-basics page notes, work well on oil-based stains such as cooking oils.

Ketchup follows the same first moves as tomato sauce: lift the excess without rubbing, then flush from the back with cold water. After that, use the detergent, stain-remover, and wash steps on this page.

Dried or older tomato stains

An older stain is harder, but it is still worth treating. ACI’s pizza guidance says the longer a stain sits, the more likely it is to need more than one treatment. After washing, let the garment air-dry. If the mark is still there, wash again. Do not put it in the dryer until the stain is gone. You may want to try a bleach that is safe for the fabric; an oxygen bleach can be a good option for colored fabrics, as that same ACI page notes, after you check the care label.

For blood and other protein stains, the first rule is different — cold water, and no hot-water start. See how to get blood out of sheets with cold water. If clothes are picking up marks in the wash itself, see why clothes get stained in the washer.

What to avoid

Hot water at the start. Begin with a cold flush from the back of the stain.
Rubbing sauce into the fabric. Lift or scrape the excess, then flush. ACI’s ketchup note is not to dab in a way that spreads it.
The dryer while the stain is still visible. Heat can make a tomato stain permanent.
Chlorine bleach on untested or non-bleachable fabric. Use a mild agent only on white or colorfast-tested fabric, or oxygen bleach where the label allows it.
Mixing vinegar or lemon juice with chlorine bleach. Keep acids and chlorine bleach in separate steps, with a rinse in between.

Frequently asked questions

Does hot water set a tomato stain?

Starting with hot water is a poor first move. ACI’s method begins with a cold-water flush from the back of the stain. Once you have treated and washed the item, you can use the water temperature on the care label, but only put the garment in a hot dryer after the stain is gone.

Will vinegar or lemon juice take out pasta sauce?

ACI lists white vinegar or hydrogen peroxide, applied with a sponge, as mild bleaching agents for white or colorfast-tested fabric, and lemon juice on white fabrics, after you have worked in liquid detergent. Rinse well, and do not use these on untested colored garments. They are a step in the method, not a substitute for detergent, stain remover, and a proper wash.

What if the stain is already dry?

Treat it anyway. You may need more than one round of detergent, stain remover, and washing. Air-dry between attempts so you can see what is left. ACI says not to use the dryer until the stain is gone, and that a bleach safe for the fabric, including oxygen bleach on many colors, can help on a stubborn mark.

Can I use OxiClean or chlorine bleach?

If the care label allows it, a bleach that is safe for the fabric can be added after the first treatments, or in a later wash if the stain remains. Oxygen bleach is the usual choice for colored washable fabrics. Chlorine bleach is only for fabrics the label says can take it. Do not mix bleach with vinegar or ammonia.
