No need to stress, there are some blood stain removal techniques that you can use to help you remove blood stains from clothing and materials easily and quickly.
Ok, first of all, if the blood stain is still fresh you must wet as soon as you can with fresh, clean water to dilute the blood and make it easier to remove with detergents. If the blood stain is on a white material you should immediately soak it in COLD water with a couple of caps of bleach.
Do not use bleach for blood stain removal if the stain is on material surface and the material is of a colour other than white, as bleach will typically discolour the material and make things a whole lot worse for you.
If the blood stain is reasonably fresh you can wet one piece of fabric and get another dry one, appkly the dry fabric underneath the blood stain and place the wet fabric over the top of the blood stain and the bottom piece of fabric will soak up the blood stain automatically.
Also, you can try wetting the blood stain and immediately applying hydrogen peroxide to the blood stain and let it start foaming. Once the foaming stops, remove hydrogen peroxide from the stain with water and see if the stain still remains, if the stain is still there, repeat the process once again with more hydrogen peroxide once more.
Using salt water also works really well on getting rid of fresh blood stains so you should also try this.
It can be a little bit tricky to remove aged blood stains but hydrogen peroxide should help you with this, test a little drop of it on a small piece of the fabric you are intending to use it on first, just to make sure that the hydrogen peroxide does not ruin this sort of material.
Actually, there is an exellent guide on stain removal that I can recommend to you called the Granny's Stain Removal Secrets.
I really hope that these blood stain removal tips will help you get rid of those blood stains.
