Sometimes it’s very hard to remove grease from pots and pans, especially the brown spots on metal pans. You can erase these and any other greasy areas by mixing 3 teaspoons of cream of tartar with 1 teaspoon of water, making a paste. Spread it on the affected areas and leave on for 15 minutes. Then, scrub the pan and the spots should have disappeared. Your pots and pans will look like new!
