10 Practical Ways To Remove Rust From Hand Tools

Working with rusty tools is a drag. Rusty tools look unprofessional and they might even make the job you are working on harder. The only way to deal with the problem is to find a way to remove the rust.

What you see as rust is just a coat of iron oxide hydrate that can occur on both iron and steel. Iron oxide hydrate is actually a chemical that forms when a metal is exposed to moisture. The level of moisture doesn’t even need to be extreme to cause rust. Just leaving tools exposed in hot, humid weather can lead to rust if they are not used regularly.

Rust is caused by a chemical process known as oxidation. Without getting too technical, oxidation occurs when oxygen and water react with a metal surface to create what is known as hydrated oxide. If it all sounds too technical, don’t worry. Removing rust from your hand tools might be easier than understanding the chemistry behind rust.

Safety Considerations

It is crucial to place safety at the forefront when addressing rust removal from tools, especially when it involves the usage of chemical substances. While these methods can be highly effective, they come with certain risks that must be addressed to ensure your well-being.

Protective Equipment

When working with potent chemicals such as oxalic acid or commercial rust removers, wearing appropriate protective gear is a non-negotiable step. Start by donning rubber gloves to safeguard your hands from any direct contact with the substances. Often, these chemicals can cause skin irritation or, in more severe cases, burns. Furthermore, protect your eyes with safety goggles. Accidental splashes can result in serious eye injuries. Wearing a long-sleeved shirt and an apron can shield your torso and lower body from potential spills.

Ventilation

Ensure proper ventilation in your workspace. This is a critical factor often overlooked. Many chemical rust removers release fumes that can be harmful if inhaled in large quantities. Working in a well-ventilated area or outside can help disperse these fumes and minimize inhalation risks. If adequate ventilation isn’t possible, consider using a face mask or respirator suitable for chemical fumes.

Safe Handling and Storage

Always read and follow the manufacturer’s instructions for the safe handling and storage of chemical rust removers. These substances should be kept out of reach of children and pets. After use, make sure to securely seal any containers to prevent unintentional spills or exposure.

Remember, safety doesn’t compromise effectiveness. Prioritizing these considerations allows you to accomplish your task without risking your health. Your tools may be invaluable, but your safety is irreplaceable.

Material Considerations

When it comes to rust removal, it’s crucial to remember that not all tools are created equal. The material composition of your tool can significantly impact both its propensity to rust and the best method for rust removal.

Iron and Steel Tools

Most hand tools are made from iron or steel due to their durability and strength. Unfortunately, these metals are particularly prone to rusting when exposed to oxygen and water. This susceptibility is due to the chemical reaction known as oxidation, as outlined earlier in this article. In the case of rust removal, virtually all the methods discussed – from vinegar soaks to chemical rust removers – can be applied to iron and steel tools. However, always remember to consider non-metal parts, such as wooden handles or rubber grips, which may react negatively to certain removal solutions.

Stainless Steel Tools

Stainless steel tools, on the other hand, have a lower risk of rusting due to their chromium content. This doesn’t make them entirely immune to rust, but it significantly decreases their vulnerability. Consequently, these tools require less aggressive rust removal methods. Mild solutions like baking soda or a simple scrub with sandpaper should suffice. Using harsh chemicals on stainless steel may lead to unnecessary damage.

Copper and Brass Tools

Although less common, some hand tools are made from copper or brass. These metals don’t rust in the traditional sense but can experience a similar process known as patination, leading to a greenish layer known as patina. This is not always undesired as it can add an antique charm to the tool. However, if you wish to remove it, a vinegar soak or scrub with salt and lime should do the job.

Always remember, the key to successful rust removal is understanding the material of your tool. A one-size-fits-all approach won’t work here. Choose your method wisely and give your tools the proper care they need. In this way, you can ensure your tools stay rust-free and functional for the longest possible time.

Rust Impact on Tool Performance

Everyday tools, whether they’re hammers, pliers, or wrenches, are often comprised of iron-based metals, making them susceptible to rust. Unfortunately, rust isn’t just a cosmetic issue; it has significant impacts on your tool’s performance.

Degradation of Material Strength

Firstly, rusting effectively eats away at the metal, causing a decrease in the tool’s structural integrity over time. The weakening of the tool can result in compromised performance and even outright failure. For instance, a rusted wrench could break during use, potentially causing harm or delaying your project.

Reduced Operational Efficiency

Secondly, rust can greatly hinder a tool’s operational efficiency. Tools with moving parts, like pliers or scissors, can become stiff or stuck due to rust. The rust adds friction, inhibiting smooth movement and making the tools harder to operate. Furthermore, rust can result in an uneven or pitted surface, which is particularly problematic for tools that require a clean, sharp edge such as chisels or knives.

Corrosion and Longevity

Finally, the long-term effects of rust can drastically shorten a tool’s lifespan. The corrosion caused by rust will continue to progress if left untreated, ultimately rendering the tool useless. As such, a proactive approach to rust removal and prevention is essential for preserving your tool’s performance and extending its lifespan.

Understanding how rust impacts tool performance underscores the importance of regular maintenance, including rust removal and prevention. Remember, maintaining your tools isn’t just about keeping them looking nice; it’s about ensuring their longevity and reliability for years to come.

In the following paragraphs, I outline 10 ways to remove rust from tools. Note that this applies mainly to hand tools. Check out one of our other posts to learn how to remove rust from power tools.

1. Soak in White Vinegar

White vinegar is a pretty popular rust removal solution for DIYers. It is cheap, it is effective, and it is completely safe to use. It works on rust by dissolving the iron oxide in place. What doesn’t come off in the vinegar can be rinsed away with water or wiped off with a rag.

Ideally, soaking a rusty tool in vinegar is the way to go. But there are certain things to consider. You wouldn’t want to completely submerge a wood-handled hammer for the simple fact that the wood won’t play well with the vinegar. If you are trying to clean a pair of needle nose pliers with rubber handles, you don’t want to submerge the rubber either.

The goal is to soak all of the metal parts in vinegar for 24 hours. Then simply rinse them with cold water and wipe away any remaining rust. If you are working with tools that you cannot submerge, you have another option: use a piece of tinfoil to apply white vinegar directly to the metal. The tinfoil doubles as a tool for scrubbing away the rust. This sort of spot cleaning doesn’t work as well as soaking, but it should do the trick in most cases.

2. Treat with Salt and Lime

The combination of salt and lime cleans up some tools just as well is white vinegar. With this solution, you will not be submerging your tools in a jar. Rather, you are going to sprinkle salt over the rusted metal and then squeeze lemon juice over the top of that. Let the tool soak for up to five hours and then scrub the mixture off.

Repeat this process as many times as necessary to get the entire tool clean. This method is a bit slower, especially since you might have to rotate the tool multiple times to treat all of the surfaces. At any rate, you can rinse away the lime and salt mixture with water and then dry the tool afterward.

3. Scrub with Baking Soda

Baking soda is an abrasive material and one that reacts well with iron oxide. To clean your tools with it, you will need a toothbrush and a small container in which you can make a paste. Note that there is no secret formula here. Just start with some baking soda and add enough water to create a paste.

With your toothbrush, apply the paste to the metal and then leave it alone long enough to set up and harden. While you’re waiting, a chemical reaction between the baking soda and metal should be taking place. You will eventually brush the hard material off with your toothbrush and rinse your tool with water.

4. Scrub with Citric Acid

A bit of citric acid in powder form can accomplish the same thing as the baking soda paste. Best of all, you can buy citric acid at most grocery stores. You will find it in the baking section. It is also fun to work with.

To start, combine a decent amount of citric acid with hot water in a bowl. You don’t want to make a paste here. Rather, you want a bubbly liquid that you can soak the tools in. And yes, you will see the bubbles form as soon as you add the hot water. Soak the tools overnight and then rinse them clean in the morning.

For some reason, this solution works best when you cover the tools overnight. So be sure to use a container with a lid. In the absence of such a container, at least cover the container with a towel or rag.

5. Clean with a Potato

I am not exactly sure about this one, but some people swear by potatoes. They say you can clean rusty tools with the cut end of a potato and a little bit of dish soap. Apparently, you cut a potato in half and apply dish soap to the exposed end. Then place the potato on the rusty tool and let it sit for a few hours. Rinse, wipe, and repeat the process until all the rust spots are gone.

6. Polish with Sandpaper or Steel Wool

If none of these liquid solutions work well enough, you can always remove rust from your tools with a little elbow grease. Try a piece of heavy grit sandpaper or steel wool. Remember, all you are trying to do is remove a layer of iron oxide. It shouldn’t be extremely difficult unless you’re looking at a very thick layer of rust.

Just use your sandpaper or steel wool to polish through the rust and down to the bare metal. You can use a damp rag to remove the iron oxide dust as you go. With a little bit of effort and a few minutes of your time, you can have your tools looking shiny and new.

7. Use a Grinder

From time to time you might be looking at tools that are so rusty that even sandpaper and steel wool won’t help. What’s the solution? A grinder. Your typical workbench grinder can handle hand tools like sledgehammers, chisels, crowbars, and so forth.

Keep in mind that using a grinder can be dangerous. Be sure you know what you’re doing before you start. Furthermore, wear protective safety gear. Protect your eyes with goggles; wear leather gloves on your hands; wear an apron to cover your torso.

8. Clean with Oxalic Acid

Another fairly aggressive solution is oxalic acid. It should do the trick on pretty stubborn rust, but you really need to be careful. Never work with oxalic acid without rubber gloves, an apron, and proper eye protection. And never let children anywhere near oxalic acid.

This solution dictates that you start by washing your tool to remove loose dirt and debris. Next, soak the tool in a 10-to-1 mixture of warm water and oxalic acid. You should only need to soak your tool for 15-30 minutes. If the rust is especially stubborn, you may have to hit the tool with a wire brush.

Finally, wash the tool with soapy water and rinse. Then dry it thoroughly. You should be all set if things went according to plan.

9. Try a Rust Converter

You can buy chemicals known as rust converters at most DIY and auto parts stores. A rust converter is intended to create a protective coating that prevents future rusting. However, it can be effective in removing small amounts of rust in areas inaccessible by toothbrushes and steel wool.

Using a rust converter is as simple as spraying your tool. Spray it on, let the tool sit for a couple of minutes, then wipe it down with a rag.

10. Use a Chemical Rust Remover *

Finally, you can always turn to a chemical rust remover if all else fails. These chemicals can be harsh, so you have to be careful with them too. An off-the-shelf product is likely to be made of oxalic or phosphoric acid. Take the proper precautions as printed on the bottle.

Rusty tools typically have to soak a while in chemical rust removers. They might also have to be scrubbed with a wire brush or steal afterwards. If you aren’t sure that your particular job requires a chemical product, you might want to try all the other suggestions described in this post first.

* Please be extremely careful when using these types of products as they are caustic and can cause injury. Be especially careful around children and pets and ensure they cannot get at, or come into contact with, any of these chemicals.

Environmental Impact of Rust Removal Methods

Rust removal, while crucial for extending the life of your tools, can present various environmental challenges, depending on the methods used. Understanding these impacts can guide us to make responsible choices that respect both our tool’s performance and the environment.

Natural remedies for rust removal, such as white vinegar, salt, and lime, baking soda, or even potatoes, tend to have minimal environmental impacts. These substances are biodegradable and typically do not introduce harmful chemicals into the environment when disposed of properly. In fact, substances like vinegar, baking soda, and citric acid are often used in eco-friendly cleaning solutions. However, one should also consider the resource cost of using food products like potatoes and limes for rust removal.

Chemical Rust Removers

On the other hand, more aggressive rust removal methods involving chemical solutions, such as oxalic acid, rust converters, or off-the-shelf chemical rust removers, can have a more significant environmental footprint. These chemicals may pose a hazard when disposed of improperly. They can contaminate groundwater and negatively affect soil and plant life if they seep into the ground. In addition, the manufacturing process of these chemicals can also contribute to pollution and resource depletion.

The Power Tool Approach

Using power tools for rust removal, such as grinders or wire brushes, can create dust particles that are harmful when inhaled and may contribute to air pollution. Moreover, energy consumption for operating these tools also factors into their environmental impact.

Preventive Measures

Prevention, as they say, is better than cure. This adage holds particularly true when it comes to hand tools. While there are numerous ways to remove rust from tools, adopting preventative measures can save you time, effort, and the potential expense of replacing your cherished set of tools.

Storing Your Tools

Good storage habits can go a long way towards preventing rust. Consider investing in a tool chest or cabinet that provides a dry, clean environment for your hand tools. Keeping tools in a damp or dirty place can encourage the formation of rust. If a tool cabinet is not an option, at the very least, use a tool roll or bag to protect your tools from direct exposure to harmful elements.

Cleaning Tools After Use

A simple yet effective measure is to clean your tools after each use. Sweat, dirt, and moisture left on tools can contribute to rust formation. Use a rag to wipe down your tools thoroughly after use, making sure no moisture or grime remains. An occasional wipe with a light oil can also help to create a barrier against moisture.

Using Protective Coatings

Finally, consider the use of protective coatings. Various rust-inhibiting sprays and waxes are available on the market that can provide a protective layer against rust. These products often work by repelling water and forming a barrier against moisture. It’s an extra step, but one that can prolong the life of your tools significantly.

By implementing these preventive measures, you can keep your hand tools in excellent shape for years to come. Not only will this ensure they’re always ready for the task at hand, but it can also enhance your efficiency and safety when working.

Post-Treatment Care

Once you’ve successfully removed rust from your tools, it’s crucial to know how to take care of them moving forward. Ensuring your tools are maintained properly after treatment will not only prevent rust from recurring but also extend the life and functionality of your tools.

Storing Your Tools Correctly

Proper storage is often overlooked, but it’s one of the most effective ways to prevent rust. Always aim to store your tools in a dry, cool environment, ideally away from concrete floors and walls, which can introduce moisture over time. Toolboxes lined with a moisture-absorbing material, like felt or wool, are a great option. If these aren’t available, consider using silica gel packs, the kind you often find in new shoe boxes, as these are designed to absorb excess moisture.

Regular Cleaning

Routinely cleaning your tools after each use can do wonders in keeping rust at bay. Simply wiping your tools with a dry, clean cloth can remove any moisture, dirt, or grease that may have accumulated during use. For tools that come into contact with sap, resin, or any other sticky substances, use a cloth dampened with a bit of mineral spirits or rubbing alcohol to clean them.

Applying Protective Coating

A protective coating, such as a light oil or wax, can create a barrier against moisture. WD-40 is a popular choice, but even a thin coat of car wax can work. For hand tools, a wipe down with a cloth lightly dabbed in oil can keep them rust-free. Do this once you’ve cleaned them and right before you put them away.

Regular Inspection

Finally, don’t forget to regularly inspect your tools. Catching rust early on can prevent a small problem from becoming a big headache. If you spot any rust during these inspections, take immediate action.

Implementing these post-treatment care methods can save you time and money in the long run, and most importantly, it will ensure that your tools are always ready to perform at their best when you need them.
