Comments about Meguiar's Meguiar's Mirror Glaze Plastic Cleaner #17:
I've been using this product to retore scratched CDs and DVDs for years. There is simply no better product out there. As long as you don't have a damaged data layer, this product can work wonders. After I use this, I use a coat of spray-on Janvil "Plastic Shine" in the 8 oz. bottle. [...] I've brought hundreds of rental DVD's back to life with this method. Remember to use soft applicator and application.
