IMO mate if iwas to correct that carpet i would: use neat industrial TFR in a trigger bottle, cover the boot carpet very generously, give it five minutes, use an industrial jet wash which u can turn the water temperature up on, which also has a very good pressure, aswell as heat (so industrial really), go for the hottest setting you can, and steam the life out of it! use a wet-vac to suck the water out, then hang it somewhere to dry if you were nearer i would do my best for nothing for a fellow ford enthusiast but as said ur not local i assume?
