I have heard of using this trick but using ammonia instead. My Grandfathers friend in Illinois did this and shot a monster some years back. My grandpa did this and ended up shooting a buck at the rag hung in the tree soaked with the ammonia. My Grandfather said when he went to gut the deer it was excited, if you know what I mean. I haven't tried it and don't think Grandpa does anymore either but I just might have too!!!
