How to Get Rid of a Detergent Stain Without Damaging the Fabric

You see blue or white marks on your clothes after washing. These are detergent stains, caused by undissolved detergent or too much detergent. They look bad but can be removed easily. Here’s how to get rid of detergent stains without damage.

A detergent stain on clothes is a residue mark caused by undissolved detergent or excess detergent that didn’t rinse out. Detergent stains appear as blue, white, or gray marks on fabric. They’re caused by using too much detergent, using cold water that doesn’t dissolve detergent, or overloading the washer.

To get rid of detergent stains, re-wash the clothes in warm water with half the usual amount of detergent, add vinegar to the rinse to dissolve residue, and dry normally. For stubborn stains, soak in warm water with vinegar for 30 minutes before re-washing. Don’t use more detergent, don’t use hot water on protein stains, and don’t put clothes with detergent stains in the dryer until the stains are gone.

Step-by-Step: Removing Detergent Stains

Step 1: Identify the Stain

Detergent stains look like blue, white, or gray marks or streaks on fabric. They often appear in patches or streaks where detergent was poured directly on clothes.

Step 2: Soak in Warm Water with Vinegar

Fill a tub with warm water and add 1 cup of white vinegar. Submerge the clothes and soak for 30 minutes. The vinegar dissolves the detergent residue.

Step 3: Re-Wash

Re-wash the clothes in warm water with half the usual amount of Tide Free and Gentle. The warm water dissolves the remaining residue.

Step 4: Add Vinegar to the Rinse

Add half a cup of white vinegar to the fabric softener dispenser. The vinegar removes residue and brightens.

Step 5: Check Before Drying

Check the clothes before putting them in the dryer. If the stains remain, soak again and re-wash. Don’t put clothes with detergent stains in the dryer.

For Stubborn Detergent Stains

Use Baking Soda

Add half a cup of Arm and Hammer Baking Soda to the wash. Baking soda helps break down detergent residue.

Use OxiClean

Spray with OxiClean Max Force Spray. Let it sit for 10 minutes. The enzymes help break down the residue.

Rub with Dish Soap

Apply a small amount of Dawn Ultra Dish Soap to the stained area. Work it in gently. The surfactants help break down the detergent residue. Rinse and re-wash.

How to Prevent Detergent Stains

Use the Right Amount of Detergent

The most common cause of detergent stains is using too much detergent. Use 2 tablespoons of Tide Free and Gentle per regular load. Don’t use more than the recommended amount.

Use the Right Water Temperature

Cold water doesn’t dissolve detergent as well as warm or hot water. If you wash in cold water, make sure to use a detergent formulated for cold water.

Don’t Overload the Washer

Overloading the washer prevents clothes from moving freely and detergent from dissolving. Fill the washer no more than 3/4 full.

Don’t Pour Detergent Directly on Clothes

Pour detergent into the dispenser or into the water before adding clothes. Don’t pour detergent directly on clothes, as it can cause concentrated stains.

Use Liquid Detergent Instead of Powder

Liquid detergent dissolves more easily than powder, especially in cold water. If you use powder, make sure it dissolves before adding clothes.

Use an HE Detergent in HE Machines

Use HE (high-efficiency) detergent in HE machines. Regular detergent produces too many suds and can leave residue.

Add Vinegar to Every Rinse

Add half a cup of white vinegar to the rinse cycle to remove detergent residue and prevent buildup.

Clean the Machine Monthly

Use affresh Washing Machine Cleaner monthly. A dirty machine can transfer residue to clothes.

What Not to Do

Don’t use more detergent. Using more detergent makes the problem worse. Use less detergent and add vinegar.

Don’t put clothes with detergent stains in the dryer. Dryer heat can set the residue. Always re-wash first.

Don’t use hot water on protein stains. If the clothes also have protein stains (blood, sweat), use cold water. Otherwise, warm water is fine.

Don’t use fabric softener. Fabric softener can leave its own residue. Use vinegar instead.

Don’t rub the stain. Rubbing can work the residue deeper into the fibers. Soak and re-wash instead.
