The best way to remove wrinkles from aluminum foil facing is to use a combination of heat and gentle stretching. First, preheat your iron on a low setting without steam. Place a thin cloth or parchment paper over the wrinkled aluminum foil facing to protect it from direct heat. Then, gently press the iron over the cloth, moving in a smooth, continuous motion. As the foil warms, it will become more pliable, allowing you to gently stretch and smooth out the wrinkles. Be cautious not to apply too much pressure or heat, as this can damage the foil.
