WD-40 original and white lithium grease are both in nearly every garage, but they serve different purposes. This comparison explains when to use each and why using WD-40 as a lubricant is a common mistake.
Our Pick
white-lithium-grease
WD-40 Original Formula
WD-40
Pros
- Penetrates corroded or stuck fasteners
- Removes rust and water from metal
- Temporarily lubricates for immediate use
- Cleans grime and adhesive residue
Cons
- Evaporates quickly — not a long-term lubricant
- Leaves residue that attracts dust
- Causes squeaks to return faster on hinges due to residue
WD-40 Specialist White Lithium Grease
WD-40
Pros
- Stays in place — does not evaporate
- Water-resistant for outdoor applications
- Handles mechanical load without breaking down
- Lasts months to years vs weeks for spray oil
Cons
- Visible white residue on dark surfaces
- Not appropriate for loosening stuck fasteners
Two cans sit on the same garage shelf, get grabbed for the same squeaky hinge, and only one of them actually fixes it long term.
WD-40 original and white lithium grease are not competitors. They solve two completely different problems, and mixing them up is the single most common lubricant mistake people make.
This comparison breaks down what each product is actually built for, and when reaching for the wrong can makes a problem worse instead of better.
What WD-40 Original Actually Is
WD-40 original (the blue and yellow can) is a water displacer — that is what the "WD" stands for. It was developed in 1953 to prevent corrosion on missile components. The formula is approximately 50% mineral spirits (a solvent), plus oil and carbon dioxide propellant.
The solvent component is what makes it effective at penetrating corrosion and loosening stuck parts. The same solvent evaporates, leaving a thin oil film that provides very short-term lubrication.
Use WD-40 original for: loosening corroded bolts, cleaning rust from tools, removing adhesive residue from surfaces, displacing water from electronics after moisture exposure.
Do not use for: ongoing lubrication of any mechanism. It will work briefly and then make the problem worse.
What White Lithium Grease Is
White lithium grease is mineral oil thickened with lithium hydroxide soap. The soap structure gives the grease its semi-solid consistency — it stays where applied under load and temperature changes.
Use white lithium grease for: door hinges, garage door tracks, automotive door hinges, drawer slides (in dry environments), and any metal-on-metal contact that needs lasting lubrication.
Do not use for: loosening stuck fasteners, cleaning rust, or applications where invisible residue is required (use dry PTFE spray instead).
The Verdict
For household and automotive lubrication: white lithium grease wins. It lasts, it handles load, and it does not create dust-attracting residue.
Keep WD-40 original for its actual purpose: unsticking corroded or seized parts.
