Clean the bent CD. Rub the CD with a soft, micro-mesh cloth. Apply light to medium pressure and wipe until the entire surface area is free from dirt and dust.
Preheat an oven on the "Warm" setting - about 100 degrees. Position the CD at center on a cookie sheet. Place the cookie sheet into the oven. Remove the CD once it is flat.
Place the CD between two glass plates. Rest a 10 pound weight – or a large, heavy book – on top of the glass plates. Drape a cloth over the top plate, before placing on the weight, to protect the glass.
Allow the weight to sit undisturbed for 48-72 hours. Remove the weight and glass, clean and play the CD.
