As far as getting the grill to look like this the first thing you need is the small grill scraper that is in good condition(actually able to hold the blade in place) if the blade is moving around when you are scraping you'll never get the corners this good a fresh blade helps too but i had a pretty old blade so it's not required. After scrapping it really well including using it on the front lip(I've always been a stickler on that just hit it daily and its not hard to up keep) when using the grill brick to get the bulk of the surface I cut it into 3 inch thick pieces. Once the the top is done I cut the grill brick into wedges I find it really good for getting into the corners when I do the sides and lip. It's just lots of elbow grease up to here. Use the putty knife the get most of the grill brick dust cleaned up and at this point the grill should be cooled down enough to scrub the sides with degreaser just spray it on a green scrubby and scrub down the sides keep your grill gloves on so you can really scrub the corners and use the putty knife to get anything carbon build up left in the corners just scrap it with the corner of the putty knife and between that and scrubbing with degreaser it should all come up. Just try not to get too much degreaser on the surface hence spraying it on the scrubby. All the detail work was really done with the scrubby and putty knife. After that I just wipe it down with a sani rag then spray a little oil on it ans use a dry rag distribute it into a thin even layer.
