Yes. Every chart is public Google Trends data, pulled 13 June 2026. The ranking is a five-year average; the season circles are five-year monthly averages; the December lines are five years of weekly data; the CleanTok line is monthly since January 2004. Worldwide. The stains themselves come from our own Stain Index.

Trends only makes queries comparable when you pull them in the same request, on one shared 0–100 scale. So the stains were pulled in overlapping groups that all shared “coffee stain” as an anchor, then rescaled onto a single axis using that anchor. That’s the honest way to say “blood beats red wine”, instead of comparing numbers Google never lined up for you.

Because almost nobody searches “super glue stain”. They search “how to remove super glue”. We held every stain to the same “___ stain” wording so the contest was fair, which means a few messes that aren’t usually called stains score near zero. It’s a quirk of phrasing, not proof those messes are rare.

“Paint stain” is contaminated by wood stain and deck stain (the product, not the accident), so it crowds out the real laundry stains. We dropped it for the same reason we left out car-oil and driveway stains: different kind of mess, wrong chart.
