After I'd done this, my problem with intermittent reading faults on my CD player is much improved. Once you figure all this out, the actual cleaning on track 8 seems to work okay, though you may need to run it several times to get it to complete. The problem is that the English instructions (track 2) tell you to jump to Track 9, meaning you miss out Track 8 the actual 40 minute cleaning track. Tracks 9 is the completion message in English, and tracks 10-14 in other languages. Track 8 is the actual cleaning track and it runs for 40 mins. Tracks 3-7 are instructions in various other languages. There are 14 tracks on the disc Track 1 is just an intro. From looking at pictures of the Wii U cleaning disc it looks different to the Wii cleaning disc and more like a regular CD/DVD cleaning kit. Problem is that if your CD lens is particularly dirty it won't play the disc properly, and it takes several goes until the lens is sufficiently clean to read it properly. Some people have tried using a can of compressed air to clean the drive when it gets dirty and I think that would be your best bet. The idea is to add a drop of the cleaning fluid to each brush and then put the cleaning CD into your CD player and play it. The right section of the package is a cleaning CD disc with two small brushes embedded in the surface. This works just fine for cleaning a CD disc, especially if you use the supplied cleaning fluid. Here is how it actually works: The left section of the package is simply a manual CD disc cleaner, comprising a plastic holder for a CD disc and a round brush for cleaning it. Instructions were inadequate and misleading.
