joe blowe and evaperconti, Thanks both of you for your suggestions. Joe I tried the water and it helped but didn't take it away. Then I tried baking powder in the hot water and let it "cook" for about 10 minutes. Again it helped. At least it doesn't smell all the time but when I cook anything I can still smell the odor. Evaperconti, I don't have any lemon but will try that tomorrow when I can get to a store. I know lemon helps with drains, hopefully it will work on this too. My microwave is only 8 months old. I'd hate to have to replace it because of this!!!!!

lpolk, of course, good old vinegar! I knew I could count on GW and Homesite people. Did that as soon as I read this last night and let it sit overnite. Kept the solution and will repeat a few more times. Much better than when I started. Think I'll try lemons too--one of the other google suggestions. Thanks, I never saw that site before and saved it. Sandy

I am no help at all!! I haven't burned anything in mine, but I do have a SS interior and it is impossible to clean!! I have done all of the steam techniques...even the one listed above and nothing works! I called the manufacturer and they sent me a product that PLAINLY states "Do not use on SS microw interiors"....huh????? Lizzie, thanks for letting me gripe on your thread...I apologize for interfering...hanging head in shame.....

I found the instructions, I didn't post it though. Its from allrecipes 4 quarts popped popcorn 1 cup brown sugar 1/2 cup margarine 1/4 cup light corn syrup 1/2 teaspoon salt 1 teaspoon vanilla extract 1/2 teaspoon baking soda 1.Place the popped popcorn into a large brown paper bag. Set aside. 2.In a 2 quart casserole dish, or other heat-proof glass dish, combine the brown sugar, margarine, corn syrup, salt and vanilla. Heat for 3 minutes in the microwave, then take out and stir until well blended. Return to the microwave, and cook for 1 1/2 minutes. Remove from microwave, and stir in the baking soda. 3.Pour syrup over the popcorn in the bag. Roll down the top once or twice to close the bag, and shake to coat the corn. Place bag into the microwave, and cook for 1 minute and 10 seconds. Remove, shake, flip the bag over, and return it to the microwave. Cook for another 1 minute and 10 seconds. Dump the popcorn out onto waxed paper, and let cool until coating is set. Store in an airtight container.
