I think this is quite an old recipe, it's been used in my family for a long time. I like it because there are no chemicals, it's inexpensive and it smells good! This can be used as an air freshener or as a personal freshener on a hot day. Try spraying your poor hot feet after a hot day of shopping. I use it to spray on my hands after dishes or housework, the vinegar is a natural skin softener.
