You can purchase "Jinx Killer" products at most occult shops or online. These are basically just versions of Uncrossing formulas, if not just artificially scented oils. However, you can make your own version. Jinx Killer gets it's name because it is believed that the liquid, when poured over a trick that has been laid for you, will "kill" the trick, even reverse it back to the person who laid it. I've decided to share my recipe for Jinx Killer. Most old-school workers know this and I myself was taught this by an older worker.
Jinx Killer Recipe
Take a bottle with a lid. Add some water and 3 capfulls of ammonia. Add a pinch of salt and red pepper. Put the lid on the bottle and shake it up while praying that the Lord destroy all evil that has been laid in your path. Next take the bottle and pour the liquid over the trick that has been laid for you outside. If you don't know where the trick is hidden then you will pour a circle of the liquid around your home.
Note: This stuff can kill your plants, so be careful using it. Since it is primarily ammonia, please show proper caution. Pure ammonia can burn the skin and it cause lung damage if inhaled.
