How to Lubricate and Protect with WD-40

WD-40 is a multi-purpose product known for its ability to lubricate, protect, and clean. It is a staple in many households and workshops due to its versatility and effectiveness. Whether you need to stop a squeaky hinge, protect metal surfaces from rust, or clean sticky residues, WD-40 can be an invaluable tool. This article will guide you through the best practices for using WD-40 to lubricate and protect various items around your home and workshop.

Understanding WD-40

What is WD-40?

WD-40 stands for “Water Displacement, 40th formula,” developed by the Rocket Chemical Company in 1953. Its unique blend includes lubricants, penetrants, water-displacing agents, and cleaning agents, making it suitable for a wide range of applications.

Key Properties

  • Lubrication: Reduces friction and wear on moving parts.
  • Penetration: Loosens rusted or stuck components.
  • Water Displacement: Prevents rust by repelling moisture.
  • Cleaning: Removes grease, grime, and adhesive residues.
  • Protection: Leaves a protective barrier against rust and corrosion.

Household Applications

Lubricating Door Hinges

Squeaky door hinges are a common annoyance. WD-40 can quickly silence these squeaks and ensure smooth operation.

Steps to Lubricate Door Hinges

  1. Identify: Locate the squeaky hinge.
  2. Spray: Apply WD-40 directly onto the hinge.
  3. Move: Open and close the door several times to distribute the lubricant.
  4. Wipe Excess: Wipe away any excess WD-40 to prevent dirt attraction.

Protecting Metal Surfaces

Metal surfaces, especially those exposed to moisture, can rust over time. WD-40 provides a protective barrier that prevents rust and corrosion.

Steps to Protect Metal Surfaces

  1. Clean: Ensure the metal surface is clean and dry.
  2. Spray: Apply a light coat of WD40 to the metal surface.
  3. Wipe: Use a clean cloth to spread the product evenly, leaving a thin protective layer.

Removing Adhesive Residues

Removing adhesive residues from stickers, labels, and tape can be challenging. WD-40 effectively dissolves these residues, making surfaces clean and ready for new applications.

Steps to Remove Adhesive Residues

  1. Spray: Apply WD-40 to the adhesive residue.
  2. Wait: Let it sit for a few minutes to break down the adhesive.
  3. Wipe: Use a clean cloth to wipe away the residue.
  4. Clean: Follow up with a mild detergent and water to remove any remaining WD-40 residue.

Automotive Applications

Loosening Rusty Bolts and Nuts

Rusty bolts and nuts can be difficult to remove. WD-40 penetrates and loosens these fasteners, making removal easier.

Steps to Loosen Rusty Bolts and Nuts

  1. Spray: Apply WD-40 to the rusted bolt or nut.
  2. Wait: Allow it to sit for a few minutes to penetrate the rust.
  3. Turn: Use a wrench to turn the bolt or nut. Reapply WD-40 if necessary.

Protecting Battery Terminals

Corrosion on battery terminals can lead to poor electrical connections. WD-40 helps prevent corrosion and ensures reliable performance.

Steps to Protect Battery Terminals

  1. Clean: Remove any existing corrosion with a wire brush.
  2. Spray: Apply WD-40 to the battery terminals.
  3. Reconnect: Reattach the battery terminals and ensure they are secure.

Lubricating Car Locks and Hinges

Car locks and hinges can become stiff, especially in cold weather. WD-40 keeps them functioning smoothly and prevents freezing.

Steps to Lubricate Car Locks and Hinges

  1. Spray: Apply WD-40 to the locks and hinges.
  2. Move: Operate the locks and hinges to distribute the lubricant.
