How to Clean the Surface
Stainless steel surfaces - Follow these instructions or watch the video tutorial on the left starting at 0:20. Clean stainless steel areas by using mild soapy water and a soft cloth. Wipe in the direction of the stainless steel grain when washing and drying. Rinse with water and wipe dry to avoid watermarks. Do not use cleaners that are abrasive or contain chlorine since both are corrosive to stainless steel. For added shine, apply a stainless steel conditioner and wipe off the excess with a soft cloth.
Stainless steel conditioners and cleaners can have negative effects on materials other than stainless steel. Do not apply stainless steel conditioners and cleaners to control labels, logos, smudge-proof or black stainless steel, and appliance interiors.
The Thermador Stainless Steel Conditioner is available for purchase in the Thermador Accessories Store.
Porcelain surfaces - Immediately wipe up acid spills like fruit juice, milk, and tomatoes with a dry cloth. Do not use a damp sponge or cloth on hot porcelain. When the porcelain is cool, clean it with hot, soapy water and a soft cloth. Rinse and dry. It is normal for porcelain to show fine lines with age due to exposure to heat and food.
Painted surfaces - Wash with hot, soapy water and a soft cloth. Rinse and dry. Do not use powdered cleaners, steel wool pads, oven cleaners, and other abrasive cleaning materials.
How to Clean the Grates
Follow the instructions below or watch the video tutorial on the right to learn how to clean the grates as well as other parts of the cooktop.
Turn off the cooktop. Remove all pots, pans, and utensils. Carefully remove the heavy grates once they have cooled down. Clean them with a mild cleaner and a soft cloth. Rinse and dry.
Acidic and sugar-laden spills deteriorate the enamel, so remove these spills as soon as safely possible.
Abrasive cleaners can mar the grates. Do not clean them in a self-cleaning oven.
If you find rust stains on the grates, try cleaning them with melamine foam. If that does not work, the grates should be replaced. New grates can be purchased online in the replacement parts section of the Thermador Store.

Burner bases - Make sure the cooktop has cooled completely before cleaning the burner bases. Clean the burner bases with hot water, mild detergent, and a soft cloth. Use a stiff nylon toothbrush to clean the port openings and do not scratch or gouge them. Rinse and dry thoroughly.
Gas igniters - After the igniters have cooled down, carefully wipe the igniters with a cotton swab dampened with water. Gently scrape the soil off with a toothpick. Avoid exposing the igniters to excessive water, as a damp igniter may not light up. Remove any lint that may remain after cleaning.

How to Clean and Season My Rangetop’s Grill and Griddle
Cleaning and seasoning your griddle, grill and grill grates can help improve cooking results and preserve the non-stick coating.
More Cleaning & Care Tips
Which cleaners should always be avoided when cleaning gas appliances?
Do not use flammable cleaners.
How do I protect the wood block accessory cover for the griddle from absorbing stains?
Protect the wood from harboring soil and bacteria by applying unscented mineral oil to the surface. Use small amounts of oil and repeat until the surface does not allow the soil to penetrate. Do not use any other types of oil for this function, as it will turn rancid over time. Reapply after scrubbing with detergent and hot water.
How do I clean the ceramic briquettes and the tray I purchased for my rangetop?
Tray for ceramic briquettes - Wash the tray with hot water and mild detergent. It can also be washed in the dishwasher.
Ceramic briquettes - Here's how to clean the ceramic briquettes:
- 1. Gently place the grease-saturated ceramic briquettes in a 6-quart or larger pot.
- 2. Fill the pot with clean water so that all briquettes are covered at least ½" deep.
- 3. Bring the water to a steady boil and then continue to boil for 10 minutes.
- 4. Remove the pot from the heat and let it cool to a safe temperature.
- 5. Remove the briquettes from the water and pat them dry with old towels or paper towels.
- 6. Allow the briquettes to air dry for at least two hours. Some visible grease stains may remain on them after cleaning.
- 7. Reassemble the clean, dry briquettes back into the tray.
CAUTION: The ceramic briquettes must be replaced when they begin to turn black. This means that they are saturated with fat and may smoke heavily during operation or the fat may catch fire.
The ceramic briquettes and the tray can be purchased in the Thermador Accessories Store.
Over time, the grates become shiny.
This is caused by using inexpensive, non-coated, aluminum pans. The texture of the grates can remove bright, shiny aluminum from the pans because the pans are non-coated. The shiny aluminum fills in the areas on the grates and makes them shiny. There is nothing wrong.
If you use non-coated, bright, non-colored, aluminum pans, try to gently clean off the shiny spots with a clean, new Scotch-Brite abrasive pad or a coarse, steel wool pad.
