Erase DVD

Anyone know of a small util that will erase DVD-/+RW?

After I have been messing around testing various DVD burns I simply want to be able to erase them so I don’t end confused which I want to keep and which I can overwrite, at the moment I am having to burn a file called blank.txt to DVD to get it erased,

I want a small standalone util (if possible) and don’t want to have to install some bloatware just to erase my media,
