Cleaning RNase - How do i clean out the RNase from my genomic DNA (Sep/28/2010 )

How do i clean out the RNase from my genomic DNA before restriction digestion. I just realised that the amount of RNase i added was not enough after runnibg a few AFLP gels. I am highly suspecting the amount of RNase i used. I also diluted the RNase very much.Is there a way of getting rid of this RNA without doing another extraction

Do another RNAse digestion with the correct amount? Why do you need to remove the RNAse before restriction digestion?
