Crash Course: Rust Remover

There’s no denying that rust is a nuisance. It commonly occurs on hand tools, auto parts, antiques, outdoor grill grates, cast iron cookware, and so much more. According to Wonderopolis, rust (the common name for iron oxide) occurs when the iron in metal objects reacts with the oxygen in water or moisture in the air.

Usually, the metal material containing the iron or iron alley must be exposed to both the oxygen and the moisture for a long period of time for rust to appear. Now that you know a little about how rust forms, let’s look at how rust removers work and which characteristics you must look for in these products.

What Is a Rust Remover?

There are a wide variety of types of rust removers as well as different methods. Among the most common methods are sanding/grinding, rust conversion, and direct application. All of the rust removers discussed above fall into the direct application category. You apply them directly to the rusted surface, usually by spraying or wiping them. Another option is to soak the rusted item in the solution. Many rust removers also treat stains other than iron oxide.

For example, almost all of our favorite rust removers work well on a variety of other household stains, such as water stains. All of our top five favorite rust removers are non-toxic. Although some of the most powerful industrial or commercial rust removers are toxic, it’s important for most homeowners to look for a safe, non-toxic product.

Rust Remover Benefits

There are a lot of different reasons to use a rust remover. These include:

  • Remove Stains – Removes the rusted stain from the object.
  • Prevent Stains – Can help prevent rust from occurring in the future.
  • Increase Usability – Sometimes rust limits the function of a tool, auto part, piece of furniture, or another object. Removal of the rust can help increases the function of that object.

In addition to these benefits, the direct application of a rust removal product is typically much cheaper and less time consuming than sanding or grinding the rusted object.

Types of Rust

You might think there’s only one type of rust – but that’s not the case. Identifying the specific type of rust you’re dealing with will help you select the correct rust remover for the job. Here are the main types of rust:

  • Flaking – Often found in a thick layer near the transition of an object.
  • Flash – Occurs from water contact in a single, direct spot on an object.
  • Pitting – Occurs in cavities of an object (such as a hinge on a pair of pliers) where moisture is trapped.
  • Stable – Uniform in appearance and occurring over a longer period of time, often covers the entire object.

Remember that most rust removers also help fight other types of common stains, such as water stains in bathtubs and showers.

How to Use a Rust Remover

There are a lot of different ways to use a rust remover. Start by reading the manufacturer directions on the product packaging. Many products can be used straight away as they come while others require dilution for the best effects. Typically, the next step involves applying the rust remover directly to the rusted object.

Scrub the area with a brush or rag. Wipe the area free of rust and rinse with water. Continue to repeat these steps until the rust is gone. For serious rust, it’s often more effective to fill a receptacle with the solution. Then soak the rusted object in the solution for 10 minutes or more before rinsing with water. Remember to completely dry the rust-free object before storage. You might also consider applying a penetrating oil or similar lubricant to prevent rust from occurring in the future.

Wrap Up

You’re sure to be happy with any of our top five rust removers. Each and every one of them is easy to use, performs well on a variety of surfaces, and is affordable to boot. That said, the clear standout is Iron Out.

As a rust removal spray, this was slightly surprising compared to full-strength liquid rust removers that you can actually dip rusted products into. But Iron Out performed well in every category. The powerful spray gel dissolves rust on first contact with little, if any, scrubbing required.

Not only does it work well on tools, auto parts, and metal surfaces, but it’s also the most efficient option for home surfaces such as the bathroom, kitchen, and even rusted carpet. Coming in second place as the clear runner up is CLR.

Short for Calcium Lime Rust, this versatile rust remover is capable of efficiently cleaning a wide variety of surfaces, including stainless steel, glass, cement, brick, fiberglass, and much more.

One nice thing about CLR is that it’s a full-strength solution. You can either mix it with water (the recommended dilution level is 50% CLR, 50% water) or use it at its 100% full-strength. Diluted is best for home applications while full-strength is best for nuts and bolts as well as tools.

Finally, we have to give one last nod to WD-40. Since it’s not a dedicated rust remover, it’s not as efficient as Iron Out or CLR, but it still works well for most applications. Plus, it has a variety of other uses, including as a penetrating oil, that make it among the most versatile products reviewed above. Keep a can of WD-40 in your toolbox and you’ll surely be thankful. No matter the exact rust remover you end up selecting, you can’t go wrong with any of the top five products from above. What rust remover will you use to bring items back to life?
