Try to get as much liquid off as possible before placing the food on the grill and if using a BBQ sauce, wait until the last 5-10 minutes of grilling before applying it to your food. Using excessive marinade and applying BBQ sauce too early in the grilling process can result in the sugar burning causing a dark color. Kindly compare with the SIZE and MODEL of your original parts before purchasing Care - Preheating your grill to 500-550 F, brushing your cooking grates clean with a stainless steel bristle brush and then adjusting your control knobs to your desired grilling temperature. It is not uncommon for food to stick more to new cooking grates. As you continue to use and clean your grates you will break them in reducing the amount of sticking.
