How do I avoid getting grease stains on my aluminum foil facing after cooking with it?

To avoid grease stains on your aluminum foil facing after cooking, consider the following tips: Use a double layer of foil to increase protection, ensuring the foil is large enough to fully cover the cooking surface. Preheat your foil before placing it on the cooking surface to reduce the chance of grease sticking. Clean the foil immediately after use with warm soapy water to remove any grease before it sets. Alternatively, you can use non-stick spray or a light coating of oil on the foil before using it, which can help prevent grease from adhering.
