VERY difficult and messy to clean!
The grill grates have thousands of "pin holes" that are used in the Infrared cooking design. These holes are very easily plugged and get blocked from grease and juice 'run-off" from grilling. When they get plugged, the cooking is dramatically affected (cooking time is increased, reduction of heat, unevenly distributed heat, etc.).
A grill brush does not reach down in the crevices of the grates to effectively clean the grease & debris to open up the "pin holes".

suggested following instructions to cook on high for 15 minutes, this did not help, it turned everything to ash and that mixed with the grease forming a thick sludge that REALLY plugged the holes. I had to let cool and poke every hole with a skinny framing nail to clear the plugged "pin holes". Still, some of the sludge remained and I had to use a high-pressure washer with very hot water to get most of the sludge off. As soon as I wiped it, the remaining sludge plugged the holes again!
This is a lot of work, it is very messy and time consuming. AND it has to be done after every grilling, or this grill will not perform as designed.
In my opinion, THIS grill IS the poorest designed grill. Very inconvenient when you simply want to grill a steak and some burgers.
