Sterilizing with alcohol?

Please excuse the attached if I have chosen the wrong newsgroup.

I need to sterilize some electrodes.  If memory serves, a biologist 
friend once told me that 70% alcohol works well as a disinfectant.  
Is this true?  If so,

(1) ethanol or isopropanol?
(2) why 70% instead of 100%?

Thanks in advance for your help,

Ben Feldman
