Thought I managed to clean the coffee spill effectively; however, few days later the scent is still there. At this stage, what is a suitable way to removed coffee scent off a rugged floor?
Most pet stores, these days, sell enzyme mixtures for eliminating pet odors. These will work on many organic odors, IF you haven't already "set" the stain by hitting it with other chemicals. (Even then, they may help. Nothing will ever eliminate all traces of the previous owner's cat from my persian rug, but it's been knocked down to a level that neither I nor my own cats find objectionable. I did have to treat both top and bottom of the rug rather thoughly, though, since the stain had soaked through.)
