![]() Higher voltages will, in essence, blast off the material that could otherwise have been reconverted. In those cases the lowest possible voltage is generally used, allowing as much iron as possible to "reconvert" back to the original surface. Your concerns about damaging the treated article are valid if you are talking about collector-quality restorations of rusty articles. ![]() Nonetheless, washing soda is much better electrolyte. With the small project shown here, the chlorine doesn't really present appreciable risk since the small volumes of gasses produced are easily dissipated. In fact, you can buy "chlorinators" that use this process to chlorinate your home swimming pool. Just google salt-water electrolysis products if you don't believe. If you use chlorides in the electrolyte mix, you will generate Cl2 gas at the anode. Use cotton swabs to clean out the inside of the drill bit until gunk stops going on your cotton swab. Get around 2 ounces of vinegar and pour it in and watch the reaction take place like the animated GIF above.įifth. Place the drill bit in your sink (i'm using a container in a sink so i can put more baking soda in)įourth. 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 Use steel wool to clean as much as you can, The drill bit was washed forcefully and although it did clean the outside layer of thread, it did not clean the inside of the thread because it is hard to get the rust out of the inside especially when it is sharp and you don't want to cut yourself so i found a solution to this problem.įirst. The pliers was easily washed with steel wool after electrolysis and got rid of all rust but because rust eats at metal, it does leave the metal with mild marks and if it were heavy rust on the pliers it would have left bigger dents trailing across the metal like the screw driver and can be smoothed with sandpaper. 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. And do not use stainless steel tools as it has a poisonous substance it produces. ![]() Also its a good idea to do this experiment outside because hydrogen and chlorine gas is produced and hydrogen can ignite very easily and chlorine is very toxic but i did mine inside because mine was not producing that much chlorine in the process and if you don't want to have the problem with chlorine gas, then instead of using salt as your electrolyte, just use Washing Soda as your electrolyte. ![]() Take a paper clip and unwind it until it has a hook shape that fits the neck of the bottle and attach a wire or alligator clip to to the paperclip like the picture above and make sure that the paperclip is in the solution except for the alligator clip because otherwise your alligator clip will get rusty.Add another alligator clip but this time to the object you want to rid of its rust and bath it completely in the solution and its fine if your alligator clip on the cathode is in the solution because it wont grow rust but always make sure that you dry your alligator clips after use.ĭo not let the two wires touch as it would cause a short circuit which stops the experiment and if you use a lithium battery to power the experiment and the two wires touch then it could literally make the battery explode but your safe without a lithium battery. If you use salt water from the ocean like i am then there is no need for adding salt. Make sure that your container is not going to be used again due to staining the container with dirty rust after use. Choosing the right container and filling it with saline solution (salt water)įill your desired container with water and add salt( the more salt the faster the process and a saturated solution will work best.
