Whenever I tell someone that I know how to remove blood from carpet, usually without a residual discoloration, they usually ask me if I do crime scene cleanup. Although I have cleaned up after crime scenes, those are not where this skill comes in most handy.
The most common occurrences of blood in carpet seem to come from children and pets. A cut on the underside of a paw or a bloody nose after a rough game of basement football is all it takes to track that reddish-colored liquid onto a light-colored carpet.
But what does someone do to get this out? Blood is one of the most difficult things to get out of carpet. I’ve discovered that the iron in our blood rusts when it comes into contact with the oxygen in the air around us. Naturally, that rusty discoloration is best treated best with rust remover. I get odd looks when I first break out my rust remover to get the discoloration of blood out, but once people see it work, they are fascinated.
The only catch is that this has to be done by a professional with a top of the line direct drive truck mounted carpet cleaning van. Rust remover is a spot treatment that is not meant to be left in the carpet. It needs to be thoroughly rinsed out of the carpet after applied.
