I bought a Wii off my friend a while ago, but 2 of the games are scratched pretty bad, and are basically unplayable.
I can't play through a game of Mario Party 8 because certain minigames give me a disc read error, and I can't get play Twilight Princess anymore because I get a disc read error when one of the cutscenes starts.
My friend bought it about 5 months ago, so I can get them repaired/replaced by Nintendo.
I was just wondering what the most effective way of cleaning/repairing a disc was. Preferably something homemade-ish. I don't want to go out and buy a whole disc cleaning kit.
