Fix Rusty Nuts and Bolts With WD-40®!

Rusty nuts and bolts can be a significant obstacle in the maintenance or restoration of any device or object. However, there are ways to loosen and remove a rusted nut or bolt with some simple methods. Let’s look at a few solutions to fix this!

Things required to fix rusty nuts and bolts:

cleaning equipment 1

  • Propane torch or a source of heat
  • WD-40
  • Metal brush or a standard brush
  • Vice grip
  • Hollow tube about two feet long
  • Wrench-sized according to the bolt/nut

Method 1 (Spray WD-40 on the rusted nuts and bolts)

  • Spray WD-40 around the rusty nuts and bolts. Wait at least ten minutes for the oil to soak in.
  • Stick the wrench in the hollow tube, and put the head of the wrench around the rusty nuts and bolts, giving you a longer wrench through which more pressure can be applied to the bolt.
  • If the box end wrench does not work because the head of the nail is damaged, replace the wrench in the hollow tube with a vice grip and try to loosen the bolt.

Method 2 (Use WD-40 and a hammer on rusted nuts and bolts)

  • Take a metal brush/normal brush and remove as much rust as you can manage.
  • Use a thread, wrap it around the bolt and spray some WD-40 until they’re completely saturated. Wait 30 minutes.
  • Strike the rusty with a hammer to try and unscrew the bolt.
  • Use a wrench to try and unscrew the bolt.

Method 3 (Use only a propane torch on the rusted nuts and bolts)

  • Take a propane torch and heat the rusty nuts and bolts by keeping the flame an inch to an inch and a half away from the bolt head. Heat the bolt for 15 – 20 seconds, and then heat the nut in a similar way.
  • Alternate between the nut and bolt for about 2 minutes, then use your wrench to try and unscrew the bolt
  • The heat should remove the corrosion that is causing the nail to stick.

Note – Do not spray WD-40 when using a propane torch as it is flammable.
