Only one way to get that foul smelling bacteria from the folds of your carpet, locallised hot water application with something as ususal as your regular washing up liquid. Don't listen to con merchants flogging miricale cures, hot water fairy liquid. rinse with more water, keeping the damping to a minimal area (obviously) leave if that option is available but anyway get it with a vacuum cleaner then a hair dryer. DON'T DAB AT IT WITH A POURUS MATERIAL you'll bleach out the dye, and any thing you do try to mop up that stain with, work inwards and contain it.
