What You'll Learn
Soak in white vinegar
So, you want to remove rust from screw heads, eh? Well, you've come to the right place. One of the best ways to do this is to soak the screws in white vinegar. This method is tried and tested, and it won't cost you a fortune in fancy equipment or chemicals. In fact, you can pick up white vinegar cheaply from any supermarket.
Here's what you'll need to do:
Step 1: Prepare the Vinegar Solution
Get yourself a bucket or container big enough to fit all your screws. Pour in enough distilled white vinegar to completely cover the screws when they're placed in the container. The amount of vinegar you'll need will depend on how many screws you're cleaning. For reference, one gallon of vinegar should be enough to soak a small item. If you're cleaning something larger, you may need more.
Step 2: Add Salt (Optional)
If you want to increase the potency of the vinegar, you can add some table salt to the solution. The general rule is one cup of salt for every gallon of vinegar. Stir the mixture until the salt has dissolved.
Step 3: Soak the Screws
Place the screws into the vinegar solution, making sure they are completely submerged. Leave them to soak for at least 30 minutes, but no more than 12 hours. Check the screws periodically—the amount of time needed will depend on how rusty they are. For heavily rusted items, you may need to leave them to soak for a few days.
Step 4: Scrub the Screws
Once you've removed the screws from the vinegar solution, it's time to scrub off any remaining rust. Put on a pair of latex gloves to protect your hands, then use a scrubbing brush to dislodge the loose rust.
Step 5: Neutralise the Vinegar
To neutralise the acid in the vinegar, mix a gallon of water with one cup of baking soda. Stir the solution, then soak the screws for about ten minutes.
Step 6: Rinse and Dry
Rinse the screws with clean water, then dry them thoroughly with a towel. Make sure the screws are completely dry before putting them away.
And that's it! Your screw heads should now be free of rust and good as new.

Use a wire brush
Using a wire brush is an effective way to remove rust from screw heads. It is a straightforward method that does not require harsh chemicals. Here is a step-by-step guide:
- Choose the right wire brush for the job. Consider the type of surface you are working on and the level of rust. For irregular surfaces or light-to-medium rust, a crimped wire brush is ideal as it provides good flexibility and reduces the risk of damaging the metal. For heavy rust removal, a twist knot wire brush is more suitable due to its aggressive action against the surface.
- Select the appropriate brush shape. Cup brushes are suitable for cleaning large surface areas, while wheel brushes are ideal for smaller, tighter spaces. If you need to reach holes or other tight spots, opt for end brushes.
- Consider the type of metal you are working on. Use a steel brush for ferrous metals (containing iron) such as carbon steel, cast iron, or wrought iron. For stainless steel and non-ferrous metals like aluminium, tin, and zinc, choose a stainless steel brush.
- Prepare the screw head by applying a rust removal spray or a lubricant spray. This will help loosen the rust and make it easier to scrub. Let the spray sit for a few minutes to allow it to penetrate the rusted areas effectively.
- Start scrubbing the screw head with the wire brush. Apply firm pressure, but avoid pressing too hard, as this can cause the wires to heat up and reduce the brush's lifespan. Target the rusted areas, including the areas where the screw head meets the installed surface and any washers present.
- After scrubbing, apply the rust removal or lubricant spray again and wipe off the excess with a dry cloth. This step will help remove any remaining rust particles and leave the screw head clean.
- Inspect the screw head. If there is still some rust remaining or stubborn spots, repeat the process as needed until the screw head is completely free of rust.
- Once the rust is removed, you can further treat the screw head to prevent future corrosion. Apply a touch of oil or grease to act as a protective layer. Alternatively, you can paint over the screw head to achieve a fresh finish.
Using a wire brush is a practical and efficient way to remove rust from screw heads. By following these steps and choosing the appropriate brush type and technique, you can effectively eliminate rust and restore the functionality and appearance of the screws.

Try a commercial rust remover
If you're looking for a quick and easy solution to remove rust from screw heads, a commercial rust remover could be your best bet. These products are designed to effectively remove rust from metal surfaces without the need for harsh chemicals or time-consuming methods.
One popular option is Naval Jelly, which is said to remove rust from any surface. Simply apply it to the affected area, let it sit for a few minutes, and then rinse it off. However, it's important to note that you should avoid getting it on paint, as it can be too caustic.
Another option is Rust Oleum Rust Remover, which comes in a gel form and is applied with a trigger sprayer. This product is also effective in removing rust from screw heads, but be aware that it may leave a grey finish.
If you're looking for a more natural commercial solution, you can try using white vinegar. Soak the rusty screws in a container filled with distilled white vinegar for about 24 hours. After soaking, simply scrub the screws with a wire brush, rinse them with clean water, and dry them thoroughly. For extremely rusty screws, you may need to repeat this process.
In addition to these commercial options, there are also various DIY methods you can try, such as using a wire brush, electrolysis, or household items like cola or lemon juice. However, if you want a more reliable and faster solution, a commercial rust remover is a great option.

Use a soft drink containing phosphoric acid
Phosphoric acid is a popular choice for removing rust from screw heads. It is a colourless and odourless mineral acid that can be found in foods and drinks, including Coca-Cola. However, it is crucial to handle it with care as it can be dangerous if not used responsibly. When phosphoric acid comes into contact with corrosion, it releases poisonous fumes, so it is important to use it outdoors or in a well-ventilated area. Additionally, it can cause severe damage to skin, eyes, mouth, and respiratory organs, so it is important to wear protective gear, such as a face shield, safety goggles, and pants that cover the skin.
When using phosphoric acid to remove rust, follow these steps:
- Use a paintbrush to apply the acid in the form of a jelly, which usually comes in a can, onto the corroded screw heads. Cover even the non-corroded parts to protect them from potential corrosion.
- Let the jelly sit on the screw heads for about five minutes or as instructed by the manufacturer.
- Scrub the rusty parts with steel wool or a wire brush. If the rust is persistent, leave the jelly on for a few more minutes before scrubbing again.
- Rinse the screws with water using a garden hose, being careful not to let the acid touch your skin.
- Coat the screws with baking soda, scrub them with a brush, and rinse them with water again.
- Leave the screws to dry outside.
If you accidentally come into contact with phosphoric acid, take immediate action. If you inhale the fumes, find fresh air and seek medical attention. If the acid gets into your eyes, wash them and go to the hospital. If it touches your skin, rinse the affected area with water and seek medical help.

Cut a new groove into stripped screws
If you're dealing with a stripped screw, there are several methods you can use to cut a new groove into it. Here are some detailed, step-by-step instructions:
Using a Flathead Screwdriver and Hammer:
- Place the tip of a flathead screwdriver on the top of the stripped screw.
- Lightly tap the end of the screwdriver handle 2-3 times with a hammer to dig into the screw head.
- Try turning the screwdriver to see if the screw loosens.
- If dealing with a rusty screw, spray a rust penetrant before tapping the screwdriver to help break apart corrosion.
Using a Rotary Tool:
- Load a cutting disc onto a rotary tool that's made for cutting metal.
- Position the disc vertically and turn on the tool so it starts spinning.
- Lightly press the tool into the screw head to make a straight line across the surface.
- After cutting a line in the screw, fit the end of a flathead screwdriver into the slot and turn it counterclockwise to loosen.
- Wear safety glasses and avoid working near anything flammable when using a rotary tool.
Using a Screw Extractor:
- Install the cutting bit of a screw extractor (a specialty drill bit with one end that cuts and one end that bites into the metal) onto your drill.
- Run the drill in reverse to bore into the middle of the screw.
- Flip the extractor to the pointed side and drill into the screw to loosen it.
- Screw extractors are reusable, so they're a good investment for your toolbox.
Using a Drill:
- Install a left-handed drill bit that's just smaller than the screw's diameter onto your drill.
- Lightly press the end of the drill bit into the middle of the screw.
- Set your drill to reverse and slowly squeeze the trigger.
- The tip will catch on the damaged screw and continue to loosen it.
Using a Dremel Tool:
- Use a Dremel tool or a similar rotary tool with a cutting attachment.
- Cut a new slot in the screw head by placing the cutting wheel on top of the screw and turning on the tool.
- Guide the wheel carefully to create a new slot.
- Once the new slot is cut, use a flathead screwdriver to turn the screw counterclockwise and remove it.
