So i've had my RF for about 6-7 month now and have used it probably close to 5-6 times. Not sure how much it was used before i bought it. Its starting to get a thick coating of char on the baffle plates, the grates are slimy always and the take has flecks of char hanging off. I was in a competition last weekend and inwrapped my ribs on the top shelf and the foil hitting the top made black flakes fall to my ribs. Luckily i had more on the bottom shelf. i'm debating putting a bunch of water pans in it and cranking up the temp really hot and "steaming" some of the crud off. What do you think about that? was also debating putting citrus fruits in the water...i've heard people cleaning house chimneys this way. How do you clean yours? Do i just simply get a hose a scrub brush?
