As far as I know, this is by far the best and easiest way to get rid of hard to remove blackened cooked on debris from your DCS cooking grid. However, these tips that I am about to share with you will work on any cooking grid whether it be stainless steel or enamel. The blackened gunk will literally just fall off.
1) Take note and make sure that the grill is not hot.
2) Remove as much of the blackened cooked on gunk from the DCS cooking grid as possible with a wire-brush.
3) Keep using the wire-brush to clean the surface that is coated with the blackened cooked on gunk.
4) Do your best to remove the gunk, but keep in mind that it does not have to be cleaned perfectly.
5) Put the DCS cooking grid inside of a garbage bag or some type of seal-able container (preferably plastic).
6) You’ll then want to add at least six to eight ounces of ammonia.
7) Close the container and let it be for at least twelve hours or overnight, it’s up to you.
Remove the DCS cooking grid from the container and proceed to remove the remaining hard to remove gunk with the wired-brush used earlier.
9) Rinse the DCS cooking grill with water and that’s it, you’re done. The remaining gunk should literally fall off the cooking grid.
