WD-40 sells sprays, cleaners, and specialty products that keep tools, machines, and homes working smoothly.
WD-40 is the company behind the little blue-and-yellow can that has lived in garages, workshops, and kitchen drawers for generations. Its core product is a spray that loosens stuck parts, drives out moisture, and stops squeaks — the kind of fix-it liquid people reach for when a hinge complains or a bolt won't budge. The company sells mostly through hardware stores, home improvement chains, and industrial suppliers, and its customers range from factories and tradespeople to ordinary homeowners.
Beyond the famous spray, WD-40 sells a family of related products: specialist sprays for heavy machinery, silicone and white lithium greases, and a line of household cleaners. These are sold under brands like WD-40 Specialist and 3-IN-ONE, and the company has grown its "maintenance products" business while its homecare and cleaning lines have become a meaningful second leg. The business model is simple and highly profitable: WD-40 makes a small, cheap product, spends relatively little on manufacturing, and spends a lot on marketing so the brand stays top of mind. That brand loyalty is the real moat — customers ask for WD-40 by name, not for "a lubricant." Headquartered in San Diego, California, the company earns money all over the world, with a large share of sales outside the United States. It has built a reputation for steady, boring excellence: modest revenue growth, strong margins, and a long history of raising its dividend. Management has also bought back shares over the years, returning cash to investors rather than sitting on it.
The risks are worth knowing. WD-40 depends heavily on a small number of products and on its brand staying beloved, and it faces competition from cheaper generic sprays and from larger chemical and tool companies. It also has to keep its retail shelves stocked and its marketing fresh, because a can that sits forgotten in a garage is a can that stops selling. Still, the company has proven remarkably durable — a rare case of a simple product, sold honestly, that has stayed useful for decades.
