What is a good stain remover for blood? I haven't killed anyone but my husband shaves before bed and then leaves tiny blood stains all over the white pillow cases. Googling around, I found [[http://www.amazon.co.uk/Hg-Stain-Away-No4-50ml/dp/B00782M268/ref=sr_1_fkmr1_2?s=kitchen&ie=UTF8&qid=1398343356&sr=1-2-fkmr1&keywords=stain+devil+no.4 THIS]] Anyone tried it, or any better suggestions?
