Step 8: Save CDs
Put a small dab of toothpaste onto the scratched side of the disc. With a soft, clean towel, rub the toothpaste over the entire disc in concentric circles, as though you were the needle on a record player*. Wipe any remaining toothpaste off with a slightly-damp towel. You could be listening to "Tubthumping" on repeat in no time.
*Ask your grandparents what a "record" is.
