I dont have to clean my grill anymore........... :C
I use a teflon/silicone sheet that I found at the RV show in Quartzsite, I was skeptical at first but some friends bought it and it worked great. You still get the grill marks on the food. It works great for fish as it doesn't stick. Grilling asparagus there is no fear of one falling through. Works great on onion slices. I could go on and on. I bought several and use them at home and on the road.
