With care not to scratch the disc, if the disc is already scratched the cleaning will not help
Most home remedies do not work. Since your disc is already unplayable it would not hurt to try anything on the disc that does not leave a film on the on game disc and dirty your disc reader lens. The best solution is to get the disc professionally polished.
I Have the game disc but i'm worried i'll scratch considering they cost £45

Check the back of a disc there might be a scratch on it. If not it might just be your PlayStation is having trouble reading the disc. Finally maybe your PlayStation is having problems.

You need a scratch remover. They can be mighty expensive. Would suggest you go to your local game store and ask them if they could repair your disc. If there's a Play'N'Trade any where around you they will repair it.

A four inch scratch is really big, probably too big for any scratch remover to fix correctly. What you need to do is take your car in to a place that fixes glass. They should have the correct tools to fix the issue.
Banana - No - You fix discs by using a kit with a series of abrasives, from course to light, to wear down scratches - step by step - to a smooth finish. Professional systems use multiple abrasives, consisting of different hardness and shapes (sharp to smooth). Regardless of product or system used, the key is to use a series of abrasives (more than one stage) to gradually bring the plastic back to a polished surface. If you want to remove all scratches on your disc, take a look at the 5-stage Scratch Pro repair kit. It will bring the disc back to its original shine and you will have a kit on hand to fix the next disc. Also do a search for scratch repair to see what is out there in your area.
