WD-40 Original Formula Multi-Use Spray 3-Pack - Smart Straw Precision

In this review of WD-40 Original Formula, the bottom line is simple: this multi-use spray is for homeowners, hobbyists, and maintenance pros who need a reliable lubricant and moisture displacer in a single can. The reviewer found the permanently attached Smart Straw convenient and praised the spray two ways design for both precision and broad coverage. For anyone who fixes squeaky doors, frees stuck bolts, or protects metal from corrosion, this product stands out for its combination of penetrating action, lubrication, and corrosion inhibition.

Key Features

• Drives Out Moisture: Quickly dries out electrical systems and displaced moisture to help prevent short circuits and restore functionality.
• Corrosion Inhibitor: Leaves a protective film that helps shield metal surfaces from rust and other corrosive elements after treatment.
• Frees and Loosens Parts: Penetrates rust-to-metal bonds and loosens frozen or stuck components so hinges, bolts, and fasteners move again.
• Lubricates Moving Parts: Reduces friction on hinges, wheels, pulleys, rollers, chains, and gears for smoother operation.
• Smart Straw Sprays 2 Ways: Permanently attached straw flips up for a precision stream and down for a regular spray, reducing lost parts and speeding use.

Who It's For

This product is ideal for homeowners doing routine maintenance, garage tinkerers, and light industrial users who want a single solution for lubrication, moisture displacement, and corrosion protection. The spray works well on door squeaks, mailbox hinges, lawn equipment, and small electrical contacts where moisture is a concern.

Those who need heavy-duty industrial greasing or food-grade lubricants for machinery with close food contact should look elsewhere, as this is a multi-use aerosol lubricant intended for general maintenance rather than specialized industrial lubrication systems.
