Delta Carbona Biodegradable Oven Cleaner - 16.8 fl oz | Heavy-Duty Degreaser for Stovetops, Racks & Kitchen Appliances | Safe for Home & Commercial Use

I had mixed results and would give the product 3 1/2 stars, if that were an option. Do not be fooled. There are fumes, just not as strong as with traditional oven cleaner. The gel does stay in place, which I love. Most of the burnt-on grease wiped away easily, (as per instructions, I let it sit for 4 hours then used gloves, a sponge and a bucket of warm water). Some, however, acted as though it were completely immune to the cleaner. In particular, the top half of the oven window wiped clean, but the bottom half remained stuck like glue. Very strange. A second treatment did not help. Most of the debris on the inside walls and bottom came off, though. I was concerned about residual smells upon the first use after cleaning, but with a thorough wipe-down, experienced no problems. To sum up, I now have a much cleaner, though not entirely clean oven, and it was easy and less smelly.
