A:Answer I bought the Weber wire brush to use on the grates and it's fine. I think it's the only way to get some carbon bits off them anyway. Small bottle Coleman propane let me heat up and cook for several hours and had to swap out at the very end. So if you were keeping an eye on it, you should get about 6 hours of prep and cook time. If you just needed to light it up for a quick house BBQ dinner, should get 2-3 dinners out of normal cook items like burgers, dogs, chicken, or maybe 2 for something like steaks.
