Why is it so difficult to clean blood from carpet?

As a porous material, carpet is challenging to keep clean under the best of circumstances. And if the carpet is present at a bloody crime site in Orlando, it’s impossible to sanitize it properly. One of the reasons why blood cleanup is so difficult is that it usually has time to settle into the carpet before it’s cleaned. If someone suffers a serious accident in the home or a violent crime occurs, cleaning a carpet stain is not a priority—and it might even be considered obstruction of justice if evidence of a crime is destroyed. This gives the blood plenty of time to thoroughly soak the carpet fibers, carpet padding, and matting. In substantial amounts, blood can even saturate the subfloor.
This means that even if you can remove blood stains from the fibers, the floor will still harbor blood. Blood cleanup can be a dangerous task that is best left to professional cleaning companies. It can contain pathogens that may cause infectious diseases, including HIV and hepatitis. Professional cleaners protect themselves with specialized gear as they remove the affected carpet, padding, and subfloor, and restore the area to its original condition.
