In lieu of fully re-seasoning your grill with each use, there are simple steps you can take to maintain and care for the condition of your grates. After each use, take a moment to run the wire brush quickly over the grates to clear away any immediate drippings. The heat in this case is helpful for removal when in smaller portions and in the moment. In the same step as above, use a pair of kitchen tongs and a paper towel to coat a layer of high heat oil over the cleaned grates before closing the grill top to cool.
Clean the bottom of the grill with a soapy sponge. Once all the chunks are gone, scrub the bottom with a sponge or scouring pad and soapy water to remove any built up grease or grime. Lots of drippings and food scraps tend to build up under the burners of the grill. Pay close attention to this area and clean it as much as possible to avoid corrosion.
