WD-40 Multi-Use Product with Smart Straw Sprays 2 Ways - 8 OZ 6-Pack

In this review the WD-40 Multi-Use Product with Smart Straw stands out as a compact, multi-purpose spray ideal for homeowners, DIYers, and light trades who need a single can that lubricates, displaces moisture and helps free rusted parts. The permanently attached Smart Straw that sprays two ways is the single biggest reason to buy: flip it up for a precise stream or flip it down for a wider spray, so the same can works for tight mechanisms and larger surfaces without losing or misplacing a straw.

Key Features

• Dual spray Smart Straw: The permanently attached straw flips up for a precision stream and down for a regular spray, saving time and preventing lost parts.
• Moisture displacement: Drives out moisture and quickly dries electrical systems to reduce moisture-induced short circuits.
• Corrosion inhibitor: Leaves a protective film that helps shield metal from rust and other corrosive elements over time.
• Penetrating action: Loosens rust-to-metal bonds to free stuck, frozen or corroded parts without excessive force.
• General lubrication: Lubricates hinges, wheels, pulleys, rollers, chains and gears to reduce friction and quiet squeaks.

Who It's For

The WD-40 Multi-Use Product is best for homeowners, handypersons and hobbyists who want a small, portable can for routine maintenance tasks like lubricating door hinges, freeing stuck bolts and protecting exposed metal from moisture. It is also useful for workshop benches or toolboxes where a single multi-function product replaces several specialized fluids.

Those who need heavy-duty industrial-grade lubricants, long-term heavy load bearings, or precise food-grade lubricants for commercial kitchens should look elsewhere, since this formula is designed for general maintenance rather than specialized industrial or food-contact applications.

Pros & Cons

Pros

• Versatile and multi-functional for lubrication, rust release and moisture displacement.
• Smart Straw design prevents losing the straw and provides both precise and wide spray patterns.
• Compact 8 OZ can size that is easy to carry and store for everyday use.

Cons

• Some users report mixed spray effectiveness with occasional cans that fail to spray reliably.
• Not a substitute for specialized industrial lubricants or food-safe products.

Specifications

Our Verdict

The WD-40 Multi-Use Product with Smart Straw is a practical, good-value maintenance spray for everyday household and workshop tasks thanks to its dual spray convenience and multi-function formula. Buy it if you want a reliable all-purpose lubricant and rust-release product in a handy 8 OZ can; consider a specialty fluid only if you need industrial or food-safe performance.

Frequently Asked Questions

Can the Smart Straw be lost?
The straw is permanently attached and flips up or down, so it avoids the common problem of misplacing a separate straw.

Is this safe for electrical use?
Yes, it is designed to drive out moisture and quickly dry electrical systems to reduce moisture-related shorts, but ensure power is managed per safety best practices.

Will it remove rust completely?
It helps loosen rust-to-metal bonds and frees stuck parts, but heavy corrosion may require mechanical cleaning or specialist rust removers.
