Using Regular Detergent

In order to clean a fresh blood stain from your sweater, first rinse it in cold water. This can help prevent the stain from setting and making it harder to remove. Next, apply liquid detergent directly onto the stain and let it sit for about five minutes. After that, scrub the area with a soft brush or sponge, then rinse the detergent away. In some cases, you may need to repeat these steps until the stain is gone.

Removing Dried Blood Stains

If you’ve discovered a dried-on blood stain on your sweater, you may need to use more aggressive techniques. First, rinse the stain in cold water to make sure that it is fully saturated. Fill a bucket with two gallons of lukewarm water and add one cup of white vinegar. Soak the stained garment in this mixture for 15-20 minutes, then rub the stain gently with a soft brush or sponge. Rinse out the vinegar, then follow up with regular detergent and cold water.

Using Household Products

In addition to regular detergent and white vinegar, there are some other common household items that can help with removing blood stains from your sweater. Hydrogen peroxide can help to break down the proteins in blood and make it easier to remove. Just make sure that you test it on an inconspicuous spot on your garment first to make sure it won’t cause discoloration. You can also try using baking soda or a combination of lemon juice and salt.

Using a Store-Bought Stain Remover

If none of the above methods work, there are a number of store-bought products available that can help get rid of tough blood stains. Look for products specifically designed for removing organic stains such as blood, and follow instructions listed on the label. Before using any type of product on your garment, always read the care instructions to make sure it is safe.
