I simply turn off the grill. Before the next cook I turn the burners on high and scrape and brush the grates while they are hot.
I might clean the drip tray at the end of the year. I empty the small catch tray when it looks like it's getting full, if the raccoons haven't gotten there first.

Hey guys. What’s everyone doing to clean your gas grill after your done cooking? I keep the heat on high so I can use a wire brush and clean the racks then wipe off the nobs and outside down with a warm dish cloth.
