What is rust?
Rust is the mixture of oxygen, water and steel and other varies metals. The reaction creates iron oxides and given enough time will react heavy enough with steel to turn it in to pure rust. The easiest method of preventing rust is to use stainless steel or other metals that do not rust such as aluminum or and titanium. Alternatively you can coat layers of steel in zinc by hot dipping it. The most widely known and common way to prevent rust is to simply paint the metal before use. Ever wonder why your car rusts when the paint chips? It’s because the raw and stainable steel is now exposed to water and oxygen.
Galvanizing steel tubes in order to prevent them from rusting
Rust is one of the worst stains to have on any surface. Rust can form inside of your house on sinks and toilets, or it can pose a nightmare to your gutters, driveway and even your plants. Before attempting to clean rust off of any material you should research how first. That is because unlike most stains rust can actually be worsened depending on what chemical you use. Bleach is one of the worst things to use because the oxidation causes the material you’re using it on to rust even faster.
How current flows form the metal to the water when metal is oxidizing
Once you notice a rust stain you should tend to it as fast as possible. Over time the rust will build up, the patch will get bigger, thicker, and harder to take care of next time you want to clean it. Another downside to not cleaning rust spots is it rubs off on everything and can stain things near the stain as well. If I have rust on my basketball hoop the rain will wash it off on to my driveway and now I will have two stains to clean up. It also poses a third problem because if I brush up against my basketball poll I will have a rust stain on my fabric cloths, along with the other two stains! This is why by catching a rust stain early can save you a lot of time in the future.
Light surface rust that should be cleaned before it spreads further
Rust originates on metals, but can stain many almost any surface. You may have rust in your toilets and sinks from metals in the pipes and faucets along with the metals in the water. It can drip on to concrete from cars or equipment. It can even stain your clothes and countertops. Rust is everywhere, and here’s how to clean it.
How to remove rust from garden tools
This video goes over removing a layer of rust on an axe. He uses only a few simple materials such as WD40, steel brush, steel wool, and a rag. You should start by running the steel brush over the blade to remove any loose particles off of it. Then spray the blade with WD40 and rub it with the steel brush again. Rub it down with the rag, and spray it once more with WD40 and then scrub it with the steel wool. This final scrubbing of the metal will remove any fine rust that’s on there, while simultaneously polish the blade. Remember, if any corrosion remains, the steel will continue to oxidize.
Remove rust
Another great and easy way to remove rust is with electrolysis. While this technique may only be viable with people for a large amount of metal needed rust removed, it is definitely the easiest and safest way to do it. This method involves removing the rust with electricity instead of acid based liquids and some elbow grease. This diagram shows the most common way to start electrolytic rust removal. On one end of the container you have your anode; on the other end you have the cathode. These are hooked up to the positive and negative terminals on the battery charger. The anode and cathode are simply pieces of metal designed to move either towards the center, or away from it depending on how big the tool is that you need to clean. Next you would put the piece of steel you need to clean on two pieces of wood sitting on the bottom of the container. You need just enough wood or another material to get the metal off of the bottom of the tank. Move the anode and cathode as close to the tool without touching it as possible, and connect the negative lead of the battery charger to the rusted tool. The last step is to simply turn on the battery charger and let the rust and corrosion fall right off. After just a few hours the water will turn extremely rusty and foamy and your tool or metal is now rust free. It will have a fine black coating on it which can be rubbed off with a towel and water. Make sure to dry and add rust prevention chemicals to the new steel or it too will start to rust. I recommend you try Zero Rust after it’s cleaned and dried.
Prevent rust
If you take care of your metal, preventing rust is fairly easy. The best way to eliminate rust formation is to coat your metal with paint or some form of protective layer. Since rust is formed by the oxygen in water reacting with the metal, putting a layer of protection between the water and metal is a sure fire way to prevent rust from forming.
You can also take better care of your metal. Simply stopping water from sitting on your tools, golf clubs, or other metal objects is a great way to stop rust. While water will not instantly rust a metal object, it will if it’s left to sit for extended periods of times. Wiping down metal edges on your snow board or golf club will prevent rust from ever getting a chance to form.
