Seasoning a grill has no relationship to seasoning the steak or eggplant you're grilling. In the latter case, you season to add flavor to the raw food item. But when you season a cast iron grill, you're not adding flavor. It actually refers to the process of coating the grill grate with oil, then heating it, to render it rustproof and create a virtually nonstick surface. Depending on the type of grill you own, you may only need to season the grill the first time you use it and occasionally after that. And with a Weber brand grill, you may not need to season it at all.
Brush your grill grates after every use (inspect for wire brush bristles before cooking), and thoroughly clean them every couple of months, depending on grill usage. And twice a year, you should give your grill a thorough cleaning, which helps it cook better and last longer. The basic process is the same for gas or charcoal grills; charcoal grills just have fewer parts.
While the grill grates and flavorizer bars are removed and soaking, tackle the caked-on gunk in the firebox. Put another bucket underneath the firebox where the grease tray sits to collect debris. The easiest way to start is with a wet/dry shop vacuum, whether full-size or a portable, like Milwaukee’s M18 hand vacuum. Since wet/dry vacs are mostly workshop items, you won’t feel bad about using one to suck up the gunk that’s collected in your grill. You can use the grill brush to help loosen stubborn stuck-on grit. If the deposits are really caked on, dip the wire brush in the bucket of soapy water and get to work. Use a hose to rinse it out when it’s clean.

After reading this guide, you're going to cruise the farmer's market with a whole new outlook on what your grill can do.
Check the fuel lines for visible defects. If any fuel lines have unmistakable damage (like rips, holes, cracks), replace the parts immediately before your next use of the grill. Also be sure that any fuel lines have a smooth trail. You don’t want any of your fuel lines to be bent, because that will prevent the gas from flowing correctly. Check the exterior of the gas tank for any damage as well; things like dents, erosion, punctures, or any evident signs of damage. If you find areas that have obvious damage, you could potentially have a gas leak.
