WD-40 Original Formula Multi-Use Product 12 OZ 6-Pack - Smart Straw

In this review the WD-40 Original Formula 12 OZ 6-Pack is assessed as a versatile household and shop staple; it is best for homeowners, DIYers, and technicians who need a reliable multi-use spray that lubricates, displaces moisture and helps free stuck parts. The single biggest reason to buy is the permanently attached Smart Straw that SPRAYS 2 WAYS, letting users switch quickly between a precision stream and a wider spray without losing the straw. The review examines day-to-day use, ease of application, and how well it lives up to common maintenance tasks.

Key Features

• Smart Straw SPRAYS 2 WAYS: The permanently attached straw flips up for a precision stream and folds down for a regular spray, saving time and reducing lost parts.
• Drives Out Moisture: Quickly dries out electrical systems to help prevent moisture-induced short circuits and restore wet mechanisms.
• Corrosion Inhibitor: Forms a protective layer to help shield metal surfaces from rust and other corrosive elements after application.
• Frees and Loosens: Penetrates rust-to-metal bonds and helps release stuck, frozen or rusted metal parts for easier repairs.
• Removes Sticky Residue: Gets under grease, gum, tar, sap, super glue and sticker residue to clean multiple surfaces without aggressive scraping.
• Lubricates Moving Parts: Reduces friction on hinges, wheels, pulleys, rollers, chains and gears to restore smooth operation.

Who It's For

WD-40 Original Formula is ideal for homeowners who maintain doors, garage hardware and outdoor fixtures, and for mechanics or hobbyists who need a general-purpose lubricant and moisture displacer. The six pack suits those who want spares for the workshop, toolbox, garage and utility closet.

It is not targeted at precision machine lubrication where specialty oils or grease are required for long-term high-load bearings, nor is it a substitute for products formulated specifically for high-temperature or food-grade applications.
