Charcoal grills do not have a lot of benefits, but they are not without their disadvantages. The main disadvantage is that charcoal grills produce an uneven cooking surface and can be difficult to clean. This is because the heat from the charcoal burns off the grease and drippings on the grill grate, so you will need to clean your grill more often. Charcoal is also difficult to ignite, so you may end up with lumps or small pieces in your food if you don’t use them properly.
