Well, you know, here in Canada, skunks are a very common sight when you live outside the city. At night they all come out from under garden sheds and roam around. If you're unlucky, if you go out at night to check if you locked the car doors and one happens to be eating grubs in the front lawn, you're in for it
This is a formula I got from Adam Savage and I can say that it works on most anything with a funky smell. And it's particularly effective on skunk spray, much more than the commercial stuff. They can't sell this formula because it breaks down very rapidly. You can't store it.
I'm lucky to never have been skunked, though the neighbor's dog has... and the neighbors tried to wash him with tomato juice... poor thing.
The original skunk-out formula is a simple 1+1+1 using baking soda, dish soap and hydrogen peroxide. When you mix the peroxide and the baking soda, it releases a lot of oxygen that attack the bacteria and molecules that cause the smell to break them down. And since skunk smell contains a molecule that stinks more when you add water and an oily substance to make it all stick, the dish soap breaks down the oil. Once it's foamed and covered the zone where there is spray, you just rinse with water and the smell is gone.
I've used it on smelly jars I wanted to re-use and you'd be surprised at how good it is. You'll actually wonder what nothing actually smells like!
