I’ve found that I like to get it done and over quickly then vac the dust and put it all back together after I’ve eaten, that way it’s ready for the next cook. I always spray my grates with grill grate spray after cleaning, it’ll stay on until the next cook. I like to clean my grates while they are still warm, everything comes off easily. I’ve got a big sink in my outdoor kitchen so it makes it easy. It’s too hard to clean them after everything sits for days on end. I used to wait and sometimes have to use the pressure washer on them. I buy some 3M paint stripping pads, they are heavy duty and they have a hand held holder they attach to to make it easy. I spray the grate with degreaser and let it sit about 20 minutes while I vac the grill and clean things up.
These are the pad I use
