How Ecolab Turned Clean Dishes Into A Contract
Hello Business Enthusiasts,
Welcome back to Business Knowledge, where every week we look at one public company that sells something forgettable and earns serious money from it. We tell the story, then dissect the habit worth stealing for your own business.
- Company in focus today: Ecolab, St. Paul, Minnesota (NYSE: ECL)
- What they sell: cleaning chemicals for kitchens, hotels, and hospitals, plus the people who come in to make sure they work.
- Read this twice if you sell a supply your customers reorder every month, and you keep losing accounts over price.
In today's issue, we look at how a carpet cleaner that barely sold in 1923 taught a St. Paul salesman to sell clean plates by the rack. You'll learn how to package your product around the result your customer gets judged on, all in about four minutes.
The room that sat empty for a week
In 1923, a stained hotel carpet meant a closed room. The rug went out for cleaning, the room earned nothing for days, and a traveling salesman named Merritt Osborn noticed.
His fix was a cleaner that worked with the carpet still on the floor. A room cleaned in the morning could take a paying guest that night.
Osborn rented a basement office in the Endicott Building in St. Paul, hired one assistant, Ida Koran, and called his company Economics Laboratory.
The product was called Absorbit, and it flopped. Ecolab's own company timeline says its limited market became obvious quickly, which sent Osborn looking for something else to sell.
The customer who paid for clean plates
Think about a restaurant owner in the mid-1920s. Dish machines were arriving in commercial kitchens, and the typical owner had no way to judge water hardness or how much powder a load needed. A rack of spotty plates went straight back through the machine, burning hot water and labor on the same wash.
In 1924 Osborn bought a cleaning compound from a University of Minnesota chemistry student, Leonard Englund. It became Soilax, a dishwashing detergent. Then Osborn did the thing that defined the company: he turned his salespeople into dishwashing consultants, and he even shot a sales film called "Dishwashing Dividends" to train them.
The salesman walked into the kitchen, watched the machine run, fixed the mix and left with the reorder. That visit holds the whole company's idea in one line: sell the clean result, and the chemical sales follow.
A kitchen manager's Tuesday, a hundred years on
Now picture the kitchen manager at a busy hotel today. Her health inspection is next week, and the dish machine is leaving a film on every glass. What she wants from a supplier is a person who will own that problem until the inspector leaves.
Ecolab sends that person. The company employs 48,000 people, and more than 25,000 of them work in sales and service, calling on customers in more than 40 industries. On a visit, they check that the systems work, collect data, train staff, and pass on fixes from other sites.
The manager signs off on a program. Detergent, rinse aid, sanitizer, and the visits come as one package, and she stops comparing the price of a drum.
Why a visit protects the price
Any decent chemist can match a dish detergent in a lab. Matching a trained person who already knows the kitchen and the inspector's habits takes years, and Ecolab has that person standing in kitchens across more than 170 countries.
The payoff shows up in the 2025 numbers. Sales grew just 2% to $16.1 billion, yet gross margin rose from 43.5% to 44.5%, which the company put down to strong value pricing. Adjusted operating income climbed 11% on that small sales gain.
A customer buying the result will also accept products that use less stuff. Ecolab's ReadyDose tablets cut plastic packaging by 98.8% against the matching liquid products, and its packaging work avoided 36 million pounds of waste in 2025. A supplier paid by the gallon would have every reason to bury that tablet.
The same visit, scaled up to water
The model kept working when Ecolab moved from dish rooms into factories, cooling towers, and data centers. Its 3D TRASAR system now watches water quality around the clock for data center operators worried about cooling water running short. The customer has changed from a cook to a plant engineer, and the job is the same one Osborn's consultants did: keep the result true and show up when it slips.
Chief executive Christophe Beck put the company's water bet in eight words: "Water is the foundation of life and business."
Selling the result in your own business
Start by finding the number your customer gets judged on. Call three of your best customers this week and ask which number their boss checks every month. A restaurant manager might say inspection scores, and a plant manager might say downtime.
An hour of calls is enough, and you'll know you've got it when two of the three answers point at the same number.
Next, rebuild one offer around that number. Bundle your product with a scheduled check-in and price it as a monthly program, the way Osborn's consultants sold clean plates. Give yourself two weeks to build it and pitch it to one friendly customer.
The signal that it's working is a customer who stops asking for your price per unit.
Then put a person on a schedule. Pick your top ten accounts and book a visit or a 30-minute video call every quarter, where you look at their results before you mention reorders. After two quarters, compare reorder rates for the visited accounts against everyone else.
Finally, test one change that helps your customer use less of your product. It feels backwards for a week. If the result holds and the account renews at the same price, you have proof they're paying for the outcome.
The salesman who never left the kitchen
Osborn's carpet cleaner barely sold. The dishwashing visit he invented next is still running a century later, with more than 25,000 people doing it every day. Find the result your customer needs someone to own, and send that someone.
