Boy, this answers my questions about using aluminum foil on the bottom of my new self cleaning oven. My coils are underneath. I was looking around and just read somewhere that a woman just ordered another bottom from the manufacturer for her oven. Her husband thought he was helping to keep the bottom clean by putting foil there.She paid about $45 for the new bottom. She did it herself (or her husband did). There are two screws they removed and lifted out the old bottom and replaced it with the new one. Done deal! Check out the manufacturers of the unit and just replace that piece. It sounds like it was worth it. She was digusted every time she used the oven with the aluminum foil stuck to it.......This may also include any silicone liners too. You will have to check with your manufacturers......Roxy

Just this past weekend, I did a full cleaning of my CC. I was inspired by seeing the brand spanking new Culinarians on the Chopped previews. I just soaked the grates in hot water and dish soap for a bit and them scrubbed them with green scotch pads. If you have thick grease on them, you can boil some water and soak them in that for a while. We use to use boiling water to clean soiled grates and burners in the restaurant and it works wonders.

Well, taking a second look, even though there was mucho rust after using the self-clean oven approach, I saw a lot of gray underneath - a good sign. So, after watching a few You-tubes on the subject - I rinsed out the pot with hot water - thoroughly dried with cloth and over gas burner, put on American Idol, and tackled it with absorbent cloths, oil, shortening and salt. I just kept cleaning and cleaning - never got it quite all off, but finally applied the recommended grapeseed oil and let it preheat in a 400 degree oven. Got engrossed in Idol - so it probably stayed in the oven for an hour. Happily, the grapeseed oil sealed it up quite solidly - and the cloth wiped over it comes out perfectly clean! The pan bottom almost matches the lid again (which had not been affected). I will do another couple of cycles of oiling and preheating. (Will post my phone photos if and when I can find the proper cable to upload.) Thanks to each of you for the input.

You should place a call to samsung tech services and ask about it. I doubt you're the first person with the issue.
