Blood stains are one of the most difficult stains to remove from upholstery because it seeps into the fabric and quickly penetrates the fibers. It's also a major source of bacteria, which can be harmful to your health and the safety of your loved ones.
First, act quickly to try and prevent the stain from setting into the fabric. If it does set into the fabric, it will leave an unsightly mark that will be permanent.
Sponge the area with cold water. Heat of any kind will make the stain set, so using cold water is essential.
Rinse well to remove the detergent from the seat fabric, then use a clean cloth towel to dry out excess water. This will allow the seat to dry properly and avoid a resale problem.
A simple spray bottle with a mixture of cold water and a teaspoon of salt will work wonders for removing a blood stain from your car seats. The salt will help absorb the excess blood, while the water helps to break up the blood fibers.
Another great way to get blood out of your car seats is by putting hydrogen peroxide into a spray bottle and saturating a rag with it. This will then be applied to the stained area and allowed to sit for a few minutes before being rinsed off.
After a few minutes, you should be able to see that the blood stain is gone. However, it may take a few applications to completely eliminate the stain from your seat's upholstery.
