How To Remove Grease Splatter And Gunk

This is a common but spectacular occurrence when a bake element fails. You can go to your local appliance parts store with your model # and they may have a replacement element in stock.
Remember to rinse the baking soda out prior to using the oven.

I poured a little amonia and used a heavy duty scrub brush to take off some of the same types of spots from a boil over. It took a little bit of elbow grease but it ewas the only thing that took it off after trying 6 or 7 different things. I hope this helps

1. Buy an empty spray bottle and some baking soda.
   You'll find that baking soda is cheap -- especially if you buy in bulk.
   
2. Using a funnel, place 3 heaping teaspoons of baking soda into the spray bottle.
   If the baking soda clogs the funnel, unclog it with water.
   
3. Wash the baking soda into the spray bottle by running water into the funnel.
   Fill the bottle with water. After the bottle fills, you'll notice undissolved baking soda that has settled at the bottom of the bottle.
   
4. Shake the spray bottle so that all the baking soda dissolves in the water.
   Unless all the baking soda is fully dissolved, some of it gets left behind in the bottom of the bottle as a residue.
   
5. When the oven is cold, spray the baking soda and water solution on to the black stuff. Do this one or more times a day.
   It is important to work on a cold oven for two reasons:
   
   • Safety. You can't burn your hands if the oven is cold.
     
   • Containment. You'll get baking soda all over the house if you start with a hot oven. I know. I've done it.
     Starting with a cold oven solves the problem.
     
6. Use your oven as you normally would. Keep spraying wet baking soda on to the top and sides of the interior of the oven between meals.
   Wet baking soda will break up the carbon sticking to the sides of the oven. Keep spraying baking soda on to the black stuff between meals until it is all gone.
   Don't worry about getting baking soda in your food. Baking soda is one of the prime ingredients of many recipes such as corn bread. It is safe to add it to your food should you do so inadvertently.
   Using this technique, the black carbon that was stuck to the sides of your oven will flow to the floor of your oven and settle there as a black carbon powder that can be wiped away.
   Your oven will look like a mess while this is in process. Choose a good time to do this.
   
7. At your convenience, when the oven is cold, wipe your oven with a damp cloth.
   Eventually, you will have to wipe down your whole oven with a damp cloth. The black carbon and baking soda will will settle together on the bottom of your oven. Both are easily removed with a damp cloth.
   In theory, you will have to apply the spray bottle many times but you should only have to wipe down your oven once. Try not to wipe down the oven prematurely as this removes the active ingredient that makes the whole thing work -- the baking soda.
   Important! Let the baking soda accumulate so that it can do its job.
   
8. Repeat, repeat, repeat until all the black carbon is gone.
   

Use Baking Soda and water and form a paste. Use this to clean the top of your stove. If food is really baked on, you might also consider using a single blade razor to scrape the mess off. Rinse well.

I want to say that since I posted my original problem with black spots appearing on the Schott Ceran top, I took pictures of the top and attached them to a complaint sent to Maytag. Approximately 3 days later, a Maytag representative phoned and offered a brand new top-basically stating that there is a fault with the tops. They would not pay for the labor to replace the top. My husband downloaded the instructions from Maytag website and installed it himself. These spots actually appear from within the surface and are not the result of a boil over, etc. The spots on my burner grew to the width of the burner. If you search the internet, you will see many others with the same problem with the Schott Ceran tops. I will never buy another!
