JML reckons it has the best solution in the form of the Disc Clinic. Out in November – yes, that is rather a long time away, isn't it? – the Disc Clinic combines a clean wash spray and the 'clinic' device itself. Insert the disc inside, turn the handle a few times, and your disc should be as good as new.
Sceptical? Well yes, we've seen the odd device like this over the years and haven't been convinced ourselves, but we'll just have to wait and see if this one is the answer to our surface scratch nightmares...
The Disc Clinic will set you back a tenner and will be on sale from ASDA, Boots, Debenhams and Woolworths, as well as online at www.JMLdirect.com.
