Regardless of the type of barbeque you have available, you can choose whether to clean cold or hot. Let's see the differences of these two modes. Hot cleaning: Before the grill cools, you can rub it with an onion or half a lemon. Obviously, be very careful not to get too close to avoid burning yourself: skewer them with a fork and rub the grill to remove encrustations. Alternatively, you can also use a special metal brush to remove excess fat, always taking care not to burn yourself. Cold cleaning: If, on the other hand, you have chatted with friends and the grill is now cold, completely remove the ash or charcoal and roughly remove the grease encrustations using special metal brushes. Alternatively, you can use a little crumpled foil to scrub the grill and remove excess fat.
