Not only is this technique simple and inexpensive, but it has also become the best-kept secret of many DIYers, mechanics, and restorers. Are you ready to find out why this mix has gone viral and how you can take advantage of it at home?

Why mix WD-40 with salt?

But by bringing these two common elements together, it unleashes a hidden power capable of removing rust, cleaning deteriorated metals, and bringing back to life tools you thought were lost.

• Properties of WD-40:
  • Remove rust.
  • Displace moisture.
  • Lubricate hinges, locks and mechanisms.
  • Clean sticky residue and accumulated dirt.

• Properties of salt:
  • It is abrasive yet gentle, ideal for rubbing surfaces without damaging them.
  • Helps enhance the cleaning action of WD-40.
  • Absorbs moisture, helping to prevent oxidation.

Materials Needed

• 1 bottle of WD-40
• 1 tablespoon cooking salt (preferably coarse salt)
• Microfiber cloth or soft-bristled brush
• Protective gloves (optional)
• Rusty or dirty surface to test

Step-by-Step Procedure

1. Prepare the surface

• Clean the surface where you will apply the mixture. Make sure it’s dry.

2. Apply the WD-40

• Spray a generous coat of WD-40 directly onto the affected area.

3. Add the salt

• Sprinkle the salt over the sprayed area, while the WD-40 is still wet.

4. Rub gently

• Use the cloth or brush to rub in circular motions.
• You will notice how the rust or accumulated dirt comes off.

5. Leave it on (optional)

• For very strong stains, leave the mixture on for 5-10 minutes before rubbing.

6. Wipe Off Excess

• Wipe with a clean cloth to remove the remains. If necessary, repeat the process.

Where can it be used?

• Rusty tools
• Old locks and hinges
• Deteriorated metal surfaces

Helpful Tips

• Test a small area before applying to the entire surface.
