In one sentence, describe what the following article is about:

Move the spatula around the stain with small circular motions.  This will loosen the debris that forms the stain and make the color fade. Mix four tablespoons baking soda and one or two tablespoons of water.  Smear the baking soda on the burned area with your finger or with a sponge.  Cover the area with a warm, damp rag.  Wait 30 minutes. After 30 minutes has elapsed, use a damp sponge or cloth to wipe the stained area.  If some of the stain remains, re-apply the baking soda paste and the damp cloth, and try again. The best cloth to wipe the area with is a microfiber cloth.  These cloths are specially designed with more fibers than a normal cloth, meaning they can absorb more of whatever you’re trying to wipe up than regular cloths.
Rub the stain with a silicone spatula. Make a baking soda paste. Wipe the area clean.
