WD-40

Known as “the can with thousands of uses,” WD 40 protects metal from rust and corrosion, penetrates stuck parts, displaces moisture and lubricates just about anything . Keep a can in your workshop to loosen bolts, stop squeaks and protect tools. Toolcraft stocks the full WD 40 range, from classic spray cans to specialist degreasers and penetrants.

What makes WD‑40 Multi‑Use Product so widely trusted?

WD‑40 was originally developed in 1953 for aerospace rust prevention, with its name standing for “Water Displacement, 40th formula” – the result of extensive formulation trials. It combines lubrication, penetration, moisture displacement, rust protection, and residue removal in a single formula, and is now sold in over 176 countries. With nearly universal recognition, the brand is often described as the tool you turn to if something that shouldn’t move, does—or vice versa.

What’s the difference between WD‑40 Multi‑Use Product and WD‑40 Specialist®?

While the original WD‑40 Multi‑Use Product is a general-purpose lubricant and protector, the WD‑40 Specialist® line offers advanced formulations tailored to specific maintenance tasks (e.g. gel-lubricants, penetrants, degreasers) for trades and industrial users. These specialist sprays deliver enhanced performance for more demanding applications.

What are some creative uses, and are there places WD‑40 shouldn’t be used?

Users have documented more than 2,000 uses—from loosening rusty bolts and removing sticker residue to silencing squeaky hinges and repelling pests. However, caution is advised: WD‑40 isn’t suitable for locks (use graphite instead), bicycle chains (it attracts dirt), painted surfaces, garage door tracks, or electronics—where it can cause harm rather than help.
