I will just leave this here


 
Just cleaned up the first of 2 grates from the Summit S420. I purchased different grates to put in that Grill and I will be repurposing these for one of my keeper grills. Almost as good as new. Close enough for me. Now I will clean the second one but I like to do a before and after pic side by side.

Really nice job. What is your method and how long did it take?
I kind of lose track of time but I would say probably about an hour. Using my DeWalt XR impact gun with a variety of wire wheel attachments first and then washing with simple green and Dawn dish soap.

I'd say these grates are good quality and thickness. But the spacing of the bars is not quite as good as 9930s or QuliMetal 9mm.
These Summit S420 grates have 13 bars per 11 3/4 grate and 9930s and QuliMetal have 15 bars per 11 3/4 grate. Here is a pic of all three

Don't get me wrong these Summit s420 grates are definitely excellent in my opinion. I'm very happy to have them and honestly even though the gap between bars is wider than some of my favorites it's definitely not noticeably wide gaps.
 
Josh, you sure do make those old grates look fantastic!

I do think the 3rd generation Summit grates are still worth the effort. Thick stainless that had minimal magnetic reaction back when I tested. Myself, I seldom use my grill for anything so small as to worry about items falling through. So, like I said in my old write-up I think the slightly wider spacing is actually good for doing crosshatch grill marks. If you do a lot of slender vegetables, though, these may not be as suitable.

I definitely agree with your original assessment 100% 👌🏼

josh, we need a proper tutorial from you. I have a set of 9930's that are 80% clean but need the extra sparkle that you get. thanks in advance!
 
@Josh Dekubber - What other grills do the s420 grates fit?
I'm finding they need modification for all my grills with my Genesis 330s being the closest fit. Fitting front to back but not side to side. With my Genesis ii 300 series grills they are only about 1/4" too big in both directions. I'll most likely cut them down for one of my Genesis 1000 restorations though.
They could be cut/modified to fit quite a few grills.
 
I was curious if they’d fit the 1000’s/silver B grills. I’ve eyeballed them and thought they were workable. But never tried or fit them to anything.
