WD-40 - Case of 12 (18 Oz Cans)

WD-40 is multi-purpose — it lubricates parts, penetrates stuck components, protects metal from rust and corrosion, and displaces moisture. It also cleans grease, grime, and other marks from most surfaces, making it useful well beyond simple lubrication in both automotive and machine shop settings.

Moisture displacement means WD-40 can push water out from metal surfaces, crevices, and parts, which is key to preventing rust and corrosion that form when metal stays wet. This makes it especially valuable after exposure to rain, condensation, or fluid spills in a shop environment.

WD-40 protects metal from rust and corrosion and penetrates stuck parts, suggesting it can help free components already seized by corrosion while also providing a protective coating going forward. It is not described as a dedicated rust-removal product, so heavily corroded surfaces may need additional treatment.

WD-40 is suited for light to heavy automotive or machine shop use, making it well-suited for high-frequency professional environments. Buying a case of 12 cans ensures a consistent supply for ongoing shop operations without frequent reordering.

In addition to protecting metal, WD-40 cleans grease, grime, and other marks from most surfaces, indicating it can be used more broadly than just on metal parts. The product does not specify every compatible surface type, so testing on an inconspicuous area is advisable on sensitive materials.

A case provides 12 x 18 oz cans, offering a significantly larger total volume that is practical and cost-effective for shops or facilities with ongoing needs. Having a full case on hand reduces the frequency of reordering and ensures product is always available for lubrication, cleaning, rust protection, and penetration tasks.
