Add about 1/2 inch of Hydrogen Peroxide to the pot. Add about 1-2 tsp of baking soda.
Heat until it starts to bubble up.
It needs the heat to start the reaction.
Simmer about 10 mins..and brush with a green scrub brush.
Repeat as needed.
It gets into the bond of the carbon and lifts it of the pan.
It will bubble and stink, so turn on your vent.
But it won't harm the enamel.
For my Creuset, I use dishwasher detergent. Make sure you buy a brand that contains enzymes (you have to read the ingredients on the label). Dissolve the detergent in hot water and let the pan soak overnight. It always works for me.
"Use a laundry detergent (like Tide or another brand with enzymes) mixed as one part detergent to three parts water in order to fill the vessel. Boil for 5-7 minutes. Allow the vessel to cool, then use a nylon or plastic scrubby as needed.
After cleaning, coat the interior lightly with white vinegar on a soft cloth or paper towel. This helps return some of the sheen back to the glaze. The longer the vinegar stays on the enamel, the more of the sheen it will return. Your vessel can be stored with the vinegar on it until next time. Wash and dry before using."
The best thing I've found is soaking the pan overnight with baking soda and hot water. Scrub the pan in the morning with a dish brush and repeat if necessary.
Try simmering some white vinegar in there and give it a little wooden sppon scrub now and again. Then when that doesn't work try salt / lemon / ice and swish it around (waitress trick for burned coffee pots) and when I say swish I mean put your back into it!
鹽可清除鍋上焦垢?
烹煮過後,鍋內留下頑固鍋漬,除了使用化學清潔劑,使用鹽也有清潔功效。有傳加鹽入鍋,開火乾炒,當鹽變黑,用廚房紙擦拭,便能清除焦垢。
專家解畫﹕「加鹽在鍋中,透過炒的動作,鹽像磨砂清除焦垢,是物理上發揮的作用,若加上化學作用,除垢效果會更理想。
食物殘留的焦垢,分酸性、鹼性和油性,
酸味食物造成的焦垢通常屬酸性,
苦的食物屬鹼性。
酸性食物污垢,可加入鹼性的梳打粉及鹽一起炒,可發揮物理及化學上的清除焦垢功效。
而鹼性食物焦垢,則可用醋或檸檬汁加鹽清除,開火加熱,有助加速化學反應。
至於油性污垢,可用梳打粉加水及鹽開成膏狀,塗在焦垢上,再用百潔布擦拭。」
