Blood Stain Removal

The sofa above was covered in blood and is constructed with natural fibres I tried all the chemicals I had on the van and I still couldn’t remove the stains . I then created my own mixture using warm water and ariel actilift, once I had rinsed the area with cold water I applied the mixture and agitated it in gently then waited 10 minutes and extracted with cold water.90% of the  stains were gone . All that was left was a slight orange outline,this is caused by iron in the blood ,I removed this with rust remover , which you can get this from all carpet cleaning suppliers
