Chem-Dry of Tampa FL has a great solution for carpet stain removal it's called Stain Out. It involves changing the red stain into a UV color that cannot be seen by the naked eye. The process takes place at the molecular level but you can see it working in the video.
The first step is to clean the spot to remove any loose debris or surface soil. After it has been cleaned and extracted the stain out solution is sprayed onto the stain. Then heat is applied to the solution to act as a catalyst and speed up the chemical reaction. The heat is applied through a steamer that heats up the carpet with, you guessed it, steam. After about 30 seconds most of the stain is gone. More Stain Out is applied and then more heat. Eventually the stain disappears. The last step not shown in the video is to stop the reaction with Stain Out Neutralizer. It stops the reaction and locks the color at its current state.
This process is Chem-Dry of Tampa FL's most powerful stain remover and it's effective on almost any stain. That being said some stains cannot be removed.
