A maker known as Dennis has released the RGR ezBuff polishing machine as open source, offering a DIY way to buff scratches out of optical disks. The project leans on practical limits—too much buffing can ruin a disc, and polishing won’t fix genuine disk rot—wh
There’s a moment every optical-media owner knows: you pull a once-smooth disk from the pile. hold it up to the light. and realize it’s too scratched to use. No amount of hope fixes a groove cut by wear. mishandling. or the kind of damage that some consoles are famously linked with—like the circular scarring associated with the Xbox 360.
For years, disk cleaners were easy to find in the 90s. Today, the shelves are filled, but trust is harder to come by. That gap is exactly what the RGR ezBuff polishing machine is trying to close. Built by [Dennis]. who posts as [RetroGameRevival]. the device does what its name promises: it buffs disks to a polish. easily.
The approach is simple enough that it still feels like it could have been built for the garage. not a warehouse. The machine is described as being 3D-printed in spirit—though the build still requires the basics: a motor and controller. There’s no crank-powered nostalgia here; if you were to turn it by hand. the project jokes it would just be a Buff polishing machine. no ez.
But the open-source nature doesn’t remove the reality check. Polishing works by taking the top layer of material off the disk to smooth out scratches. That means there’s a line between rescue and damage. The machine can’t make miracles out of every problem: too-aggressive buffing can ruin a disk beyond repair. and some scratches are simply too deep to save. And even with the best polishing setup, genuine disk rot can’t be reversed by buffing.
Still, the maker’s optimism has a practical basis. In their experience, scratched disks are more common than rotten ones—so polishing is often aimed at the problems people actually run into.
The project is also framed as a community gift. It was apparently released on Dennis’s birthday, turning a personal milestone into something other collectors and retro players can use when their own discs end up in the “maybe trash” pile.
That timing lands on a bigger shift. With Sony getting out of the disk game. physical media is becoming more precious than ever—so tools that can extend the usable life of existing discs feel less like a hobby and more like preservation. There’s even a playful suggestion tucked into the discussion: if you really want disks to last. maybe it’s time to bring back CD caddies.
The tip for the project came from [Dean], via timeExtension.com, and now the ezBuff polishing machine joins the growing roster of open builds aimed at keeping old technology functioning—one scratched disc at a time.

So it just grinds the scratches off? feels like a hack but whatever.
I don’t get how this helps if the disk rot is already there. Like if it’s “too scratched” then it’s too scratched? Idk maybe for surface stuff only.
Wait is this for Xbox 360 ring scarring discs? Cuz my buddy said that’s permanent or whatever. If this is open source I might try but I’m scared it’ll just make it worse and then I’m out like 20 games.
Open source polishing machine sounds cool but also sounds like another way to destroy stuff at home. The article was kinda all over the place saying “buffing takes off the top layer” so how is that not damaging? Also Sony getting out of disks?? feels like everything is disappearing lol. I’m just saying CD caddies should’ve never died, that’s the real fix.
