WD-40 Original Formula Multi-Use Spray 11 OZ 12-Pack - Smart Straw

In this review the WD-40 Original Formula Multi-Use Spray is examined for homeowners, mechanics, and light industrial users who need a single, reliable product for lubrication, moisture displacement, and cleaning. The single biggest reason to buy is its versatility: the can both lubricates moving parts and drives out moisture to help prevent short circuits and rust, all while offering a permanently attached Smart Straw that sprays two ways for precision or broader coverage. For anyone who wants one multipurpose aerosol on the shelf, this product delivers consistent, familiar performance.

Key Features

• Drives out moisture: Quickly dries electrical systems to reduce the risk of moisture-induced short circuits and helps restore equipment after exposure to water.
• Corrosion inhibitor: Forms a protective film that shields metal from moisture and corrosive elements to slow rust formation on tools and parts.
• Frees stuck parts: Loosens rust-to-metal bonds and helps release frozen or seized fasteners and hinges for easier maintenance.
• Removes sticky residues: Cuts through grease, gum, tar, sap and sticker residue for cleaning surfaces before repair or repainting.
• Lubricates moving parts: Reduces friction on hinges, wheels, pulleys, rollers, chains and gears to restore smooth operation.
• Smart Straw sprays 2 ways: A permanently attached straw flips up for a precision stream or folds down for a regular spray to suit the task.

Who It's For

This product is well suited to homeowners, hobbyists, and tradespeople who need a single, compact spray that covers lubrication, moisture displacement, and cleaning tasks. It works particularly well for routine tasks like quieting squeaky doors, protecting hand tools from surface rust, and freeing stuck bolts during small repairs.

Those needing heavy-duty industrial lubrication or oil-based long-term bearings grease should look elsewhere, since WD-40 is a multi-use spray designed for many tasks rather than a dedicated, heavy-load lubricant. Also, if precise long-term lubrication specs are required for critical machinery, a specialty lubricant may be more appropriate.

Pros & Cons

Pros

• Versatile: combines moisture displacement, corrosion inhibition, lubrication and cleaning in one can.
• Smart Straw design: permanently attached straw offers both precision stream and regular spray without losing a nozzle.
• Effective for household tasks: customers report strong performance on squeaky doors and protecting tools from rust.

Cons

• Not oil-based: some users expect an oil-like lubricant and note mixed results for heavy lubrication tasks.
• Perceived value and nozzle durability: a few customers comment that spray nozzle quality and value for money can feel mixed on frequent use.

Specifications

Our Verdict
