It’s important to note that even the best CD repair kits can’t work miracles. They are capable of improving the condition of abused or neglected discs, but this may not be enough to retrieve the contents without some level of degradation. The kit comes with three different polishing solutions: 1 is a cleaner that removes dust, debris, and static from your discs. 2 is a light abrasive that can remove fine scratches (and will probably do the trick for most CDs). And 3 is the strongest abrasive, for use on deep scratches. The trick to using this kit may seem obvious, but it’s worth stating: read the instructions and follow them carefully. Unlike motorized CD-cleaning machines and other automated disc repair devices, this kit requires elbow grease and patience. But if you’re willing to put in some time to manually polish your damaged media, users swear by this product’s effectiveness. And because it’s an all-purpose acrylic polish, you can use the Novus kit to restore your car’s headlights, plastic fish tanks, plastic furniture, and much, much more. The SkipDr is designed to repair minor scratches that cause skipping or otherwise affect the media’s readability. It will not be effective on more severely damaged or deeply-scratched discs.
