Hi
Did one on a large white rug about 2 weeks back, dog had walked it in, another splodge elsewhere and 2 tracks marks had gone across the rug.
Applied a solvent with a cloth to get most of it out, pre spray the whole rug and clean with my EnviroDri machine (had my red cape on as well :
)
Came up a treat, my only regret is that I forgot my camera!
Regards
Martin
