Why Does Vinegar Remove Rust
You will not find a single metallic object that doesn’t get rust.
After each rainfall or snowy winter, you will find rust on your motorbike handles, tools, pipes, even in the car too.
What is the solution to get rid of this problem? Yes, you can give a paint coating on some metallic objects but not on all objects.
You will be surprised when you will come to know that there is one solution that is available in your hand distance.
Don’t wrinkle your eyes. The solution is white vinegar.
Now, I believe one question is playing in your mind; why does vinegar remove rust?
In this article, you will get the answer to this question. Also, I will discuss the process of removing rust using vinegar too. Hang on with me.
What is Rust?
Rust happens when metal or metallic objects come in contact with water for an extended period. And combines with oxygen following the oxidation process. As a result, metal gets corroded by the process, and a chalky-reddish substance appears on the metal that is known as rust.
The best way to get rid of rust is, keeping the surface of metal away from water and keeping it dry. But this offer is impractical. You can’t always do it.
From the market, you can buy rust removing products to get rid of rust, but those products are not environment-friendly, as well as you have to keep them away from children.
Except for those rust removing products, there are some other solutions available. And the good news is, those solutions are available in your home too. If not, purchase it from your nearest store. Out of some available solutions, white vinegar is one of them. White vinegar is a great solution removing rust from any metal.
How White Vinegar Works on Metal to Remove Rust?
If you are irritated enough for stubborn rust, use white vinegar.
Rust gets removed if it comes in contact with acetic acid. And white vinegar is a good source of acetic acid. It is acidic enough that can dissolve rust with an immediate effect.
Smaller things like earrings, keys, rings, bolts, screws, and many more items can get rid of rust if you apply vinegar on them.
Dip the small items in vinegar, or you can pour vinegar on those items. Then use an old cloth to wipe the rust out. Make sure; you have given a thorough rinse after taking it out from the vinegar. Because if vinegar remains on those items, the surface may get damaged.
Step by Step Process: Removing Rust Using Vinegar
Step 01: Preparing the Vinegar Solution
Take the Large container and fill it up with 1 gallon of distilled white vinegar.
Remember, the container should be made of a non-reactive material like plastic or glass. Take a cup of table salt and mix it well with the white vinegar.
Do you know what’s the responsibility of salt in this solution? Adding salt will confirm increasing the acidic potency of the white vinegar. And the solution will be much more effective on rust. For smaller objects, you can mix 1 – 2 cup of salt to 1 – 2 gallons of white vinegar.
You are all done preparing the solution.
Step 02: Soaking the Object
Take the rusty object and give it a well-soak to the vinegar and salt solution. The object needs to be well-submerged. Now you have to give a rest to the item for the next 12 hours to a few days based on the level of the rust. If the rust level is less, 24 hours’ rest is enough to remove the rust. But if the rust level is severe, you may need to wait for a few days.
Don’t think that after dipping, you don’t need to do anything except waiting. Look at the item periodically to know how much rust has been removed by the solution from the metal.
Note: Vinegar doesn’t show the same characteristic to all metal type objects. Let me give you an example. Aluminum items have a protective oxide coating on them, and vinegar removes this coating before it starts to corrode the aluminum itself. It means, if you soak aluminum to vinegar for an extended period, aluminum will start damaging.
That is why it is advisable to check the item periodically that is submerged into the solution.
Step 03: Take the Object out from the Solution and Scrub it
Take a pair of rubber or latex gloves and wear them on to save your hands from rust. You will find some loosened rust attached to the item. Take a rough item and scrub the loosened rust from the object. The rough item can be steel wool, a brass-bristle brush, or even wrinkled aluminum foil. You can use anything available with you.
Step 04: Rub the Item with a Pad
Take another big container where you need to make a solution with water (1 gallon) and baking soda (1 cup). Take the rust-free object and soak it to the solution. Then wait nearly 10 minutes. This way, the acid of the vinegar will neutralize.
After 10 minutes, take the item out from the solution; if required, scrub it again using an abrasive item. There might be some additional moisture available with the item that needs to be removed. To do this, soak a pad to denatured alcohol and rub the item down.
Finally, to keep the item free from rust in the future, use light machine oil and rub it again.
Once you finish the process, don’t forget to give a well-rinse and an air dry. If the item remains wet, rust will attack again. And I believe you don’t want this.
Following the above effective process, you can keep a lot of small items safe from rust. It is a scientifically proven process that will work 100% successfully. Don’t forget to give a pat to your back after a successful D.I.Y. project.
