Strong acids will dissolve rust, but they will also dissolve paint, finishes, and sometimes even the metal itself. Baking soda = sodium bicarbonate. Because the natural process of rusting is an electrochemical spontaneous reaction, during the electrolytic derusting, this reaction is put in reverse. Your electrolysis procedure is now complete. My conclusion was that the pitting on a freshly derusted artifact had already existed before derusting. Get a spoon of baking soda and mix it with a few drops of water till it becomes a thick paste and rub it all over the drill bit where you need to clean just like the picture above, Third. I'm not having much luck with vinegar and steel wool. Electrolysis is a way of turning direct current (DC power) into a chemical reaction to produce hydrogen and oxygen and during this reaction the anode is forming large quantities of rust and slowly eats away at the anode while the cathode is doing the opposite and is bubbling hydrogen constantly and during that it cleans away rust which is exactly what we are going to do. Then when the electrolysis starts, a gaseous mixture of Chlorine (Cl2) and Oxygen (O2), begins to evolve bubbling off the anode. Hook up your power supply (i used 5v from an arduino) and your cathode should start bubbling like the photo i have shown while the Anode (paper clip) grows rusty sludge and makes the water turn dirty as you can see by the animated GIF above. What about different types of tools because other tools might be harder to wash with steel wool and i'm going to relate to that with a drill bit and a pair of pliers. The electrolysis CANNOT undo damage caused by the rust.
