To make the mop, in a medium pan over medium heat, heat the oil. Add the onion, garlic, and chili. Cook for about four minutes, stirring often, until the onion is soft. Add the Apple juice, vinegar, catsup, and Worcestershire sauce, soy sauce, and hot sauce. Mix well and cook for 10 minutes, stirring occasionally. Let rest for 15 minutes to steep. Strain the mop mixture through cheesecloth or small strainer, then transfer to a spray or squeeze bottle. Set aside.
