FAQs

How long should I wait for the product to work?

The penetration time can vary. For light rust, a few minutes may suffice. For heavy rust, wait 15-30 minutes or even several hours for best results.

Can I use it on electrical components?

While it is generally safe for most applications, it is not specifically designed for electrical components. If you must use it near electrical components, ensure the power is off.

Is it safe for plastics?

It is generally safe for many plastics, but it is always best to test it on a small, inconspicuous area first, as some plastics may be sensitive.

What should I do if the nozzle clogs?

Try cleaning the nozzle with a pin. If that doesn't work, replace the nozzle with a new one.

Does it prevent future rust?

It helps to protect against future corrosion but is not a permanent rust inhibitor. It is best to follow up with other corrosion protection methods if long-term protection is needed.

Can I use it upside down?

Yes, thanks to the 360° valve, you can use the spray in any orientation.

What is the shelf life?

The product has a long shelf life when stored correctly. Check the can for an expiration date, but typically it is several years if stored properly.

Troubleshooting

Seized part still won't budge after application.

Reapply the spray, allow more time for penetration (up to several hours), and try again. Use gentle force, and consider tapping the part lightly with a hammer to help the penetrant work its way in. Heat may also help.

Spray nozzle clogs.

Clean the nozzle with a pin or replace it with a new one. Ensure the can is shaken well before each use.

Spray leaves a residue.

Wipe off any excess product with a clean cloth. For delicate surfaces, use a solvent-based cleaner.

Setup, Compatibility & Care

  1. Preparation: Clean the area to be treated of any loose debris.
  2. Application: Shake the can well. Apply the spray directly to the rusted or corroded area, ensuring complete coverage.
  3. Penetration Time: Allow the product to penetrate the rust and corrosion. The time needed varies depending on the severity, from a few minutes to several hours for heavily corroded parts.
  4. Action: After the penetration time, attempt to loosen the part or remove the rust. Reapply if necessary.
  5. Compatibility: WD-40 Specialist Penetrant Spray is compatible with metal, alloys, rubber, plastic, and most paints. However, it's advisable to test on a hidden area first, especially on sensitive plastics or painted surfaces.
  6. Care: Store the can in a cool, dry place away from direct sunlight and heat sources. Keep the can upright when storing.
