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.
The uses shown and described for WD-40 Multi-Use Product were provided to WD-40 Company by the users themselves.
