CD/DVD cleaning for dummies?

Does anyone know of a safe and reliable method for cleaninh CDs or DVDs using items one might find around one’s house, or, failing that, something reasonably easy to aquire?

Toothpaste. Wet the disc with a damp rag/paper towel, then take toothpaste, and put it on the wet rag. Rub the rag together till it foams, then rub it along the disc.

Always worked for DC games.

I just use furniture polish :P.

Could try a cottonball with a bit of alcohol, let it air dry and then check the cd again.

Go to a store and buy a cleaning kit. They’re like, $10.
