Despite this, more and more people are starting to recognize the importance of maintaining a DVD and Blu-ray collection as the transition to digital media sparks concerns and conversations about personal media ownership. Before you assume a scratched DVD is beyond saving, though, it's worth trying a few methods that many collectors and thrifters — like those on Reddit's r/PS3 forum — rely on. They're some of the more accessible home remedies for scratched DVDs, but it's important to keep in mind that their effectivity varies depending on how bad the scratches are. So, when you clean the scratches off the DVD, you're simply polishing the plastic layer to make the data layer readable again. Moreover, you should wipe using soft materials like cotton balls or microfiber cloth, and not abrasive materials like terrycloth or kitchen towels.
