1) Our grill brushes go through extreme testing before they reach your hands to ensure that all bristles are securely fashioned. However, it is always possible for a single bristle to slip out after years of use. Be sure to always check your grills surface before cooking to ensure that metal bristles never end up in your food.
2) Your grill will always be easiest to clean while hot, so either clean directly after grilling, or after preheating.
3) Since brass bristles are softer than steel, they are perfect for those porcelain enamel and non-stick grates.
