We're managing to avoid the big grill scrub this year as we just purchased a new Smokey Joe on Sunday (ours was stolen last summer!) but for those doing the cleaning task tomorrow, here is a recipe from Mrs. Meyers for a green way to get the grate ready for the portabellas without resorting to harsh chemicals...
Step 1: Place the grate on the ground, remove any big pieces of cooked on stuff with a grill brush.
Step 3: Use a paintbrush to paint this paste on the grate.
Step 4: Let sit for 15 minutes, then use a strong stream of water to remove the mixture. Follow up with a scrubbing sponge or brush.
