Fuel Purchasing and Storage
With a gas grill, you need just a propane tank for fuel, and perhaps a back-up tank. A standard 20-pound propane tank fill can last for 20 cooking hours or more. For charcoal grills, you must store bulky bags of charcoal, and take care that they are in a dry storage location. Most bags of charcoal also have only a handful of grilling sessions’ worth of fuel in them.
After cooking with a gas grill, one needs only to turn the burners on high for a few minutes, then scrape down the cooking grate to remove any cooking remnants. A thorough cleaning of the grill is only necessary every six months or so. With a charcoal grill, in addition to cleaning the cooking grate, you must wait until the charcoal has thoroughly cooled, then remove the charcoal ash before the next cooking session. This can be quite a messy operation and can result in a face full of dirty ash as you clean up.
