When boiling milk, it only takes a second for the milk to boil over and burn on the cooktop. It's imperative to clean it as soon as possible because it can interfere with heating and can cause smoke.
There are several cleaning options. Simply follow the tips that match your type of cooktop to remove the burned milk without damaging the surface.
Glass and Ceramic Cooktops
Burned milk on a glass or ceramic cooktop can be a seriously smokey problem if not addressed quickly. To fix the problem, follow these steps.
Step 1 - Making the Paste
First, pour as much baking soda as you'd like into a bowl. You will be making a paste which can be stored in an airtight container. Next, add small amounts of warm water to the baking soda and stir until you form a paste.
Step 2 - Cleaning the Cooktop
Mix a small amount of detergent with water until soapy, then clean the cooktop with a paper towel. Dry the cooktop off with a lint-free towel, and then rub the baking soda paste over the burned milk on the cooktop. Wait about an hour, then use the razor scraper to remove the paste like you're shaving. Make sure the razor is as flat as you can get it.
If the burned milk is still hanging around, you can repeat this step.
Step 3 - Buffing and Finishing
Once the burned milk is gone, you can buff the cooktop so that it looks good as new. Mix white vinegar and warm water at a 1:2 ratio. Dip a paper towel into the solution and scrub the cooktop down. This is a slow process, but it is important if you want that "new-looking" shine back.
Finally, dampen the lint-free towel and wipe down the cooktop to remove the vinegar and any residue. Do not use the cooktop until it's completely dry.
Metal and Standard Cooktops
Milk and other things that are spilled and burned on standard cooktops are much easier to clean than they are on glass or ceramic models, but there are more cracks and crevices to deal with. Here's how to proceed.
Step 1 - Burners
Fill your sink with warm water and add a cup of baking soda, stirring until the baking soda has dissolved. Place the metal risers into the water, allow them to soak for about an hour.
After the burners have soaked, remove them from the water and set them on top of a towel, letting them air dry with the baking soda mixture coated on. Then rinse off with normal water, gently rubbing off any loose food materials with paper towels.
Step 2 - Cooktop and Underneath
Mix water and dish detergent at a ratio of 2:1, and fill a spray bottle with it. Add a drop of vinegar for those tougher spills. Spray the solution onto the cooktop, and let it sit for ten minutes. Use the scouring pad to scrub the sprayed area and remove the burned milk.
Next, use a damp, lint-free towel to wipe off any residue. Lift the top of the oven up to reveal the burners and reservoir area, then repeat the same procedure you applied to the cooktop. Lower it back down once it is thoroughly cleaned, and replace the metal risers.
