DH spilled a full latte on our living room rug 2 days ago and now it smells like death. Turns out he attempted to clean it by pouring clean water over it repeatedly and soaking it up with towels. 
Obviously I'll LTB. But also...can it be salvaged? Is it worth scrubbing with fairy liquid? Is there another trick?
(It's taken me this long to locate the source of the smell because it doesn't smell like coffee - it's sort of a sour pooey smell, and I hadn't been able to isolate it to this spot in the living room. So I've been hunting the house for rogue nappies / wipes; cleaning pram and scooter wheels; inspecting shoe soles etc.)
