Smudginess?

People spend hours staring at their screens every day, but they rarely notice how dirty they are. Windex’s campaign used a simple black screen to reveal the invisible problem of smudges, turning dirty screens into an unmissable ad and driving a massive boost in sales.

The goal was to launch Windex Electronic Wipes to a younger, ad-skeptic audience that typically ignores the glass-cleaning category. The challenge was to make this invisible problem—smudged screens—impossible to ignore and drive purchase intent for a product they didn’t know they needed.

People spend hours staring at their screens, but the constant light and bright colors make smudges and grime invisible. This insight revealed a cultural blind spot: the dirt was right in front of their faces, but they couldn’t see it.

The campaign turned dirty screens into the ad itself. A pure black static image was launched on social media, acting as a mirror to reveal the smudges on viewers’ screens. Paired with the simple message, "Smudginess? Wipe it," the campaign created a wake-up moment that couldn’t be ignored. It wasn’t just an ad to watch—it was an experience that made the problem visible and drove immediate action.

The campaign delivered extraordinary results. Windex Electronic Wipes saw a 67% year-over-year increase in sales on Amazon, driving a 31% overall brand sales increase. Additionally, the campaign generated a +791% surge in brand website views, successfully turning an overlooked problem into a commercial success. By leveraging a cultural blind spot, Windex created a campaign that resonated with a younger audience and delivered measurable business growth.
