Surface tension is an important factor in lubricant penetration, as it dictates which fluid will win in a direct competition for space, important when you’re trying to displace moisture from joints, hinges, screws and other tight spaces to improve movement.
WD-40 has a lower surface tension than a number of competitor products.
We placed a drop of WD-40’s Multi-Use Product next to a drop of competitor product on a flat sheet of metal, to show how WD-40 will push back against the competing liquid, forcing it out of the space rather than mixing with it.
The outcome? Proof that WD-40 will penetrate faster and further than competitor products.

Unlike its Smart Straw predecessor […]
Our triggers video is a nod to our engineering heritage as much as anything. WD-40 has been synonymous with two things in its history – the blue and yellow can, and the little red straw. Our red straws provide precise and direct application in hard to reach places, allowing users to target very specific areas […]
