GizmoJoeApr 21, You say you only have the anode on the bottom of the container? Since the process is line of sight you could get a better job if you added another anode or two to the container to surround the part more. Too much sacrificial steel though and you'll need lots of amps to do the job. Slower less amps is better to retain the strength of the part to be cleaned.
Hydrogen embrittlement is a bit of an issue too with high amps. There is a fair bit of discussion about that in the tech articles too. Cooking the part for a while is usually advised for manifolds and parts that need a high amount of strength. The main reason I flipped on you is because I saw someone read a post like that and actually try it. NOT pretty.
Enough DC amps through the water can be nasty if you grab the anode and cathode while the juice is flowing. Seen that too. Man did his eyes light up! John Candy was one of the best ever Giz OK, I'll add another rod to the other side.
That manifold is sort of awkward too. I've got mine tied up with tie wraps and a wood stick.All Rights Reserved. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Hottest Questions.

Many elements are discovered by electrolysis, many technological processes are based on electrolysis. Asked in Chemistry Who invented electrolysis?A rusted fuel tank can pose a considerable problem for any vintage motorcycle enthusiast, especially as replacement tanks are becoming increasingly difficult to obtain. To combat this, many enthusiasts use a method called electrolysis to introduce an electrical current into a solution that fills the tank.
The current displaces the rust from the tank's interior, which is then attracted to a piece of sacrificial steel anode. The entire process is fairly straightforward, but does require some preparation to ensure the best results. Expect the entire project to take a minimum of 48 hours to complete. Remove the fuel tank from the motorcycle and drain out any remaining fuel. Remove the fuel valve from the tank, either by unscrewing it directly from the tank or by removing its mounting screws with a screwdriver.
Flush the tank out with fresh water to remove any traces of fuel. Seal the portion of the tank that connects to the fuel valve. If your tank uses a bolt-on valve, then use a strip of rubber as a gasket then screw a piece of aluminum over the mounting point. Use a threaded rubber or plastic cap to seal a screw-on valve's spigot. Create a sacrificial anode using either a length of steel rod or a wire coat hanger. Bend the wire or rod into an L-shape that will extend into the fuel tank.
Select a rubber plug that will fit into the fuel tank's filler neck to act as an insulator to separate the anode from the fuel tank. Cut a small hole into the plug using a sharp knife. Push the anode through it until it extends at least three inches above the plug. Place the sacrificial anode and its rubber plug into the fuel tank's filler neck.
Move the anode around to ensure that it does not come into contact with the sides of the fuel tank. Remove the anode and plug and make any adjustments as needed.
Prepare the electrolytic solution that will fill your fuel tank, using percent sodium carbonate washing soda and water. Mix one tablespoon of washing soda for every gallon of water needed in a separate container. Make enough solution to fill your tank completely.
Insert the sacrificial anode into the fuel tank until the rubber cap is seated lightly against the tank's filler neck. Move the anode around slightly to ensure that it does not touch the sides of the fuel tank. Connect a volt automotive battery charger to the sacrificial anode and the fuel tank.
Clip the battery charger's positive alligator connector to the extended portion of the anode, then clip the charger's negative alligator clip onto a section of the fuel tank. Turn the battery charger on to begin the electrolysis process. Allow the process to continue for a minimum of 24 hours, then turn the battery charger off. Withdraw the sacrificial anode and remove and rust deposits with a steel brush.
Reinsert the anode and continue electrolysis for another 24 hours. Repeat as needed until rust deposits do not form on the anode. Turn the battery charger off and disconnect its alligator clips from the fuel tank and the anode. Drain the electrolytic solution from the fuel tank, then rinse the tank thoroughly with fresh water. Rinse the tank again, using acetone to remove any moisture from the fuel tank's interior.Electrolysis can get costly if the services of a skilled electrologist are used to remove hair on large areas of the body.
Doing electrolysis yourself the homemade way can be cost-effective. However, it's important to choose the right tool and learn correct techniques for home electrolysis. Electrolysis is considered the most permanent method of hair removal. However, if you can't find a skilled electrologist in your city or lack the financial means to pay for electrolysis treatments, home treatment can be effective.
However, this means acquiring the required skills so that you don't injure your skin and cause infection and scarring. Before you decide that home electrolysis is for you, consider the area that you're treating. If it's a small area, such as the chin or upper lip, you might come out ahead by seeking the services of a professional. Home electrolysis for facial hair is ill-advised. Electrolysis practitioners charge by the hour. Small areas of hair, such as the brow or upper lip, can effectively be treated in an hour.
Often, consumers confuse home electrolysis devices with electric tweezers, which are a dubious method to remove hair, as hair is a poor conductor of electricity. As early asthe U. Federal Trade Commission removed some brands of electric tweezers due to deceptive advertising--in other words, the product did not work as it claimed.
A home electrolysis device uses an intricate, barely-there probe needlewhich is inserted through the skin next to the hair follicle.
The device delivers an electric jolt to kill the hair root. The probe is on springs that allow it to enter the skin at a certain depth and no further.
It usually takes about 20 seconds to treat each hair follicle--five seconds to locate the hair root and another 15 seconds to deliver enough electricity to kill it. Home electrolysis devices can be purchased online under brands such as One Touch Home Electrolysis. Some people buy professional electrolysis machines.
But be aware that in some states, it's illegal to purchase and use these machines if you are not a trained electrologist. If you've never performed electrolysis on yourself before, practice on a small area of skin, such as on a leg or thigh. The American Medical Association's Committee on Cutaneous Health and Cosmetics recommends that you only treat areas of the skin that are accessible, such as the lower arms and legs.Ancient Origins has been quoted by:.

In our desperation, we'll even gamble on exotic potions and remedies that promise to cover, neutralize, or eradicate the stuff. While our threatening arsenal of abrasives and chemicals vow to undo decades of decay, they may just reassign the damage to our own fragile innards. When elbows up in some caustic bath or hours into breathing pulverized silica, it's easy to wonder if there's a better way.
There is. For some time now, restorers who work with relatively delicate objects like clocks and antique tools have very effectively removed rust from intricate steel mechanisms and massive iron castings without damaging either the parts or themselves.
Unlike caustic, acidic, or abrasive techniques, this process doesn't generate a toxic aftermath. Nor is it expensive. In fact, you could probably do it right now with the stuff in your garage. The process is called electrolytic rust removal, and while it's been around for some time, it's probably one of the least-known methods.
While it has its limitations, it's safe for both parts and the environment see "Safety and Disposal" sidebar. It also has something else going for it that no other method can reliably duplicate: It can break the tenacious bonds that otherwise freeze rusty mechanisms and fasteners in their place. The newly converted often marvel at how easy parts disassemble after even a brief treatment.
Read on. How It WorksRust is the byproduct of an electrochemical reaction between positively and negatively charged electrodes in the presence of an electrolytic solution.
In our case, the electrodes are the metal components of our cars. The electrolytic solution is nothing more than a fluid that facilitates an electrical flow. In this case, the electrolytic solution is the salt-laden water melted snow and road salt or mildly acidic solutions carbon dioxide and water in which our cars operate.
For rust to exist, two things need to happen: oxidation and reduction. When oxygen combines with iron, it takes electrons from the iron.
When that happens, we say the iron oxidizes gains a positive charge and the oxygen reduces gains a negative charge. Once that reduced oxygen encounters a lesser- or negatively charged part through the electrolyteit will surrender its spare electrons. When that happens, we say the oxygen is reducing the other metal.
Even though this reduction is unfamiliar, it's pretty cool and we can use it for our purposes. As outlandish as it sounds, it means the reduction process actually converts the oxidized material that clings to good steel back to a simple iron compound.
While this converted metal skin won't replace lost metal and isn't as strong as the metal below it, it's stable and will take paint without rusting any further. After all, the unstable rust is gone. To pull this feat off, we just need to conjure up electrons. That's easy; we just have to intentionally oxidize a piece of scrap material.
True to our earlier claim, the process itself is very simple. Since electrolysis on this scale requires very little wattage or amperage, an ordinary six- or volt car battery or battery charger does the trick although the battery method requires an ammeter. Our electrolytic solution consists of nothing more than a basic mix of one to two tablespoons of sodium carbonate, otherwise known as washing soda, per gallon of plain ol' water.
Any non-metallic container that holds both water and the part you'd like to scrub will do. The process requires scrap ferrous metal to act as an anode positive charge ; the part you'd like to clean becomes the cathode negative charge. There's also another, in this case sixth, element to this equation: time. While this type of conversion in this case, reduction won't take as long as it took for oxidation to pock the edges of that Stromberg baseplate, it will take a few hours of waiting on your part.
Personal experience has proven that this is a process best left to an overnight plunge once again, see "Safety and Disposal" sidebar for additional information. If you can fight your instant gratification urges, you'll reward yourself with a near-effortless means to effectively eliminate rust without damaging yourself, your parts, or the world around you.Electrolysis is the act of driving a chemical reaction with DC current.
Inside a simple electrolytic cell, current usually passes through a conductive liquid to cause a chemical reaction to take place. Electrolysis of fresh water is used to produce the pure gasses hydrogen and oxygen. If a solution contains metals then electrolysis can be used to isolate and to purify those metals or to coat an object with a metal. This process is called electroplating or electrophoretic deposition.
Anodizing as well is a process that uses electrolysis to increase corrosion resistance. The body of an anodized aluminum flashlight for example, was dipped in an electrolytic cell in which the polarity is reversed from normal electroplating. While normal electrolysis is often used to remove rust from antique artifacts, rust patinas can actually be deposited upon items like roof sheathing or automotive parts using the reverse polarity — anodizing process.
Galvanization, electroplating and anodizing are preformed daily by industry but can also be accomplished at home on a smaller scale. Shortly before the American and French revolutions two contemporary Italian professors were having a disagreement about what electricity was and where it came from.
The symbol for a battery is a stylized representation of a voltaic pile. One of the most popular introductory scientific experiments for school children is to construct a voltaic pile using a stack of copper coins and aluminum foil — separated by paper and with an electrolyte of lemon juice or brine solution.
Normally electrolytes are liquid but occasionally can be either gaseous or solid too. Franklin somehow associated a line of connected Leyden jars crated in a tray — with a line or battery of cannon protruding from the side of a warship. Leyden jars had only been invented, independently, a couple of years beforehand by a German and a Dutchman.
Leiden is a city in the Dutch province of South Holland.
Electrolysis of Water
Conversely, in an electrolytic cellvoltage is applied to the electrodes and electrical energy is converted to chemical energy. Negative ions anions are attracted to anode; positive ions cations are attracted to the cathode.
In a voltaic cell however the polarity of cathode and anode are reversed. This discrepancy is attributable to the theory that an anode should release electrons and undergo oxidization, whereas the cathode should undergo reduction. Rust is caused by iron giving and oxygen taking electrons — the iron oxidizes or looses some of its surface electrons to atmospheric or surrounding oxygen which is very reactive and ever hungry for more electrons.
Reduction is the gain of electrons or a decrease in the oxidation state of an atom. In the rust removing electrolysis process water is oxidized at the anode, oxygen is produced as the anode corrodes and ions or salts of metal slowly enter suspension within the electrolyte.
At the negative terminal — the DC power source supplies electrons to the cathode where reduction occurs water and rusty item accept electrons or ions and lots of little hydrogen bubbles are produced. Acids like vinegar acetic acidhydrochloric or phosphoric acid can be used to remove iron oxide from rusty items. Acids in this application however can be destructive to rusted antiques and artifacts and this is where simple electrolysis might be preferable.
Many carbonated soft drinks will remove rust to a degree also. There are in essence, two kinds of rust. Red rust exfoliates or expands. Black rust can be reclaimed and reduced back to metallic iron. Any deep pits beneath a badly rusted surface will not be filled up, but the surface magnetite will be stabilized — its molecules invigorated with new electrons to reform iron.
After drying off, rusty objects cleaned this way will quickly regain rust so therefore should immediately be protected with oil, paint, varnish or something similar. Stainless steel contains chromium and should be avoided for use at the anode because poisonous gasses and dangerous chromates could be produced in the electrolyte.
This electrolysis process also produces small amounts of pure oxygen and hydrogen so the project should be preformed in a well ventilated area and any sparks or flame should be avoided.
Since fresh water is such a poor conductor of electricity it needs to be amended with other substances before it will conduct, and therefore participate in electrolytic ion exchange.
