How to stay safe when you remove a rusted screw

When you’re removing rusted bolts and screws, it is important to take some key safety precautions.

  • Always wear protective gear. This should include gloves as well as eye goggles and a surgical mask to prevent you breathing in rust particles if they come loose as you remove the screw.

  • Take care when using strong rust removal products. Always follow the manufacturer’s instructions, and work in a well-ventilated area.

  • If you’re using heat to remove the rusted screw, wear leather gloves and ensure there is a fire extinguisher to hand in case of an emergency.

  • Make sure children and pets are kept well away from the place where you are working to remove the screw.

Two hacks for rusty screw removal: remove a stuck screw with our simple guide

Here are our top hacks for how to remove a stuck screw that’s crusted up with rust:

1. Use a hammer and screwdriver to remove a rusted screw

  • Wear gloves to protect your hands if you slip, and goggles and a surgical mask in case of rust shards or particles which may come loose during this process.

  • Strike the screw 2-3 times with a metal hammer. This will break the rust seal causing the screw to be stuck.

  • Spray on a commercial rust penetrant. This will soak the screw and help to loosen the rust and act as a lubricant.

  • Using the hammer, tap the screw a few more times, and the area around the screw too.

  • Using the screwdriver (ensuring it is the right one for the screw type) you should now be able to remove the screw.

  • If it is still stuck, use a gripping paste to keep your screwdriver in place. Always follow the manufacturer’s instructions for products such as these.

2. Removing rusted bolts and screws with heat

  • Use a water-based degreaser to wipe down the screw.

  • Make sure the area is fully cleaned, as you do not want anything flammable going up in flames unexpectedly.

  • Wear leather gloves and keep a fire extinguisher close by.

  • Heat the screw using a blow torch until it begins to smoke.

  • At this point, add cold water immediately.

  • Repeat this heating and cooling process 2-3 more times. The heat makes the screw expand, the cold causes it to contract and together they help the screw to become loose.

  • Once you have checked the screw is cool enough to touch after this process, use a screwdriver to remove it.
