Just wipe with rubbing alcohol. Do NOT use toothpaste to fill in scratches. Not unless you want your DVD player or CD player gummed up from it. DVD and CD players use a laser to read the disc, meaning that it will heat up any toothpaste on the disc causing it to drip into the inner workings which will cause bigger problems in the long run. Instead, if you have some with scratches, don't throw them out. Get the SkipDr (my kids call it the Doofensmirtz evil de-scratchinator). It costs about $45 but it pays for itself on the first use at least it did for us since the first thing we salvaged was a $50 video game. We've since salvaged several more video games and movies. This is a good thing to have until they figure out how to make DVD's and CD's and video game discs more durable.
