Some People Say you can put tooth paste on it
and others say you can steam it i would put tooth paste on it.
Also if you have several scratches on your disc just simply try putting alcohol on it. Preferably a strong one.
If it didn't it wouldn't be an xbox 360 disc cleaner
clean it with a soft cloth.
Gamestop will clean some xBox 360 game discs.
I dont think you can sorry
yes you can
You need 2 restart your console and then go clean ur disc with a Nintendo DS screen cleaner that is really soft or go 2 your car and rub the disc on the top of the inside of your car!
insert the disc mabye?
yes
download the updates from the official xbox 360 website then burn them on to a data disc then put the disc into your xbox 360 and install the updates.
It is to hard or risky to do it yourself. I suggest you go to a gamestop where they have a disc cleaner.
buy disk cleaner from the store.
yes just damp a cloth or something and wipe it softly but if it a circle around the disc you're scrwed
