Clean pan bottom
Once again, my son was a guest and put a pan in the next pan and this in leftover fat and this great mix in the morning for his fried eggs on the glass ceramic stove.
The stove went clean. But the pan: Beautifully crisp and dark brown, the part was about 20 minutes in rinse water and then I sprinkled because of lack of cleaners, some crystalline citric acid (baking ingredient) and salt over it.
The whole thing after about 15 minutes of exposure, rubbed off with a cleaning sponge and was thrilled with the result! I tested it on an old pan again. It worked wonderfully.
