In following article, procedure of polishing the glassy carbon electrode is described.

Polishing of your electrode can be accomplished by putting a few drops of water/1.0 micron alumnina slurry onto a polishing pad. The electrode is polished using a figure 8 motion to avoid grooving the electrode. In cases where the electrode has larger scratches, 1, 3, 5, or 15 micron diamond paste can be used, first working down incrementally until the 1 micron alumina can be used. Once the electrode has been polished, it should be rinsed with water, then sonicated in acetone, ethanol or distiiled water for few mins to remove any residual particulate matter if present. Hope this helps!!
