Yes dilute with water (I don't do it exactly, just put a couple of caps of vinegar in a jug and dilute with water (not too much) for a small area. It gets rid of smell and stain, in fact I use it a lot with general household cleaning. A friend of mine spent about £6 buying a spray that said it did the same in PAH, but the dog kept coming back to the carpet so it couldn't have masked the smell very well. However, I have found the vinegar solution to be really effective.
