I'd buy that for a $: Retro bargains

They'd look at you like you've two heads if you asked if they opened it to check.

CeX used to charge €1 for cleaning a disc, I think this was to deter people selling in DVDs that they'd get 10c for as they were crap. Then they decided to clean discs for free to improve store buys. It's all a numbers game. They'd still reject laser burn 360 discs.

Unfortunately when a till is busy buying 50-100 DVDs it takes a lot of time and also space behind the till. They wouldn't be able to clean many discs but should use good judgement or at least the fingernail test.

There was times where a disc was cleaned before sending out but was too bad then I'd have to source a replacement or refund. Before in-store refunds on online orders was a thing we'd get a ton of media back that even Stevie Wonder could see was scratched.

When people sent orders into the office for us to buy I'd happily sit there cleaning 20-30 discs. If there wasn't too many discs I'd give them a clean for minor scratches. It's satisfying to do and always fun seeing how well they can clean up. Usually a 30 second clean, 1 minute for a good few scratches. Laser burn on 360 discs does actually come out on a 5 minute cycle.

Anytime a 360 disc came back as unreadable I'd clean it then install it to the hard drive to ensure it 100% works as just booting to the menu could still freeze an hour into the game.

The older green/black cleaning machines were fairly problematic. They'd clog with polish solution, the pads would wear quickly or the tray the disc sits on would get dirty and end up scratching the picture side. It would also throw up random errors and you'd have to Google the error code to turn off and on again and give it a slap to work. The newer blue/grey machines are much better.

Sorry for the long post over cleaning discs haha.
