Try to look in a past Field and Stream magazine. I remember seeing something like what you speak of in an August or September article. I was going to try it, but the price for spray in the store ended up being about the same price as making it myself. Good luck. I think the main ingredients were something like unscented shampoo, distilled water, baking soda and something else. Try and find that article in Field and Stream though. I would give it to you, but I threw that month out. Let us know how it turns out if you do it.
