There are a lot of ways to "skin a cat" (so I've heard - I've never actually done it) so most people try this and that product and eventually come up with a combination that work for them. I have had good luck with the Vacaway line of encapsulizing stain treatments, and have a box of these products sent off with each of my Packages. You can also do online searches using such search terms as "remove blood stain from carpet" and find a lot of useful information in this manner as well.
