Eco Window Cleaner - 1L is backordered and will ship as soon as it is back in stock.
"After 25+ years cleaning up polluted soil and water, we turned that same science on the products inside your home."

What Customers Say After the Switch
From greenwash-burned shoppers to allergy households — here's what changed when they swapped in Sampson.
Two ingredients. After 15 years of buying glass cleaner with an INCI list longer than a bread label, this is the obvious answer. Mirrors and stovetop are spotless, no chemical smell.
I have asthma. Conventional glass cleaner has been a trigger for years — I'd hold my breath while spraying mirrors. This one I can use without a single reaction.
Works as advertised. Wish it was sold in a refillable concentrate format — going through the 1L quickly on big windows. The 3.6L helps.
Glass stovetop, mirrors, the toaster oven door, the patio doors — same bottle, no streaks anywhere. The smell is just clean — actually clean, not perfumed clean.
What you're spraying into the air you breathe at face height
Glass cleaner is the wrong place to learn what "ammonia exposure" feels like.
Conventional glass cleaners are ammonia-based and applied as a fine spray — at face height on mirrors, onto stovetop glass that heats the fumes, inside bathrooms with the door closed. Sampson Eco Window Cleaner is two ingredients: water and one plant-derived surfactant. No ammonia, no phthalate-carrier fragrance, no VOCs.
Ammonia is listed by Health Canada as a respiratory irritant — airway inflammation rises with chronic low-level exposure (Health Canada)
Indoor VOC levels are 2–5× higher than outdoor — up to 10× during cleaning (EPA TEAM)
Conventional glass-cleaner SDS sheets list 6–12 components plus an undisclosed "fragrance" blend that can hide phthalates (Industry SDS review)

We Spent 30+ Years Cleaning Up Contamination. Then We Checked Under the Sink. Nous avons passé 30+ ans à décontaminer des sites. Puis nous avons regardé sous l'évier.
Diana Trasente and Angelo Diadelfo are environmental engineers with Master's degrees and over 30 years remediating contaminated soil and water across Canada. They know industrial chemicals intimately — PCBs, heavy metals, synthetic surfactants, petroleum solvents. Diana Trasente et Angelo Diadelfo sont des ingénieurs en environnement avec des maîtrises et plus de 30 ans d'expérience en décontamination de sols et d'eau au Canada.
Then they started reading the labels on their own household cleaners. The same classes of synthetic chemicals they spent their careers cleaning up were sitting in their kitchen, bathroom, and laundry room. Puis ils ont commencé à lire les étiquettes des nettoyants ménagers chez eux. Les mêmes classes de produits chimiques qu'ils passaient leur carrière à nettoyer se trouvaient dans leur cuisine, salle de bain et buanderie.
In 2010, they founded Sampson Eco Shop — applying the same scientific rigor to household cleaners that they applied to environmental remediation. Every product starts with one question: What's actually in here, and is it safe to put down a drain? En 2010, ils ont fondé Sampson Eco Shop — appliquant la même rigueur scientifique aux nettoyants ménagers qu'à la décontamination. Chaque produit commence par une question: Qu'est-ce qu'il y a vraiment dedans, et est-ce sécuritaire de l'envoyer dans un drain?
“Every cleaner we make starts with the same question we'd ask on a contamination site: what's actually in here, and what happens when it goes down the drain?” “Chaque nettoyant qu'on fabrique commence par la même question qu'on poserait sur un site contaminé: qu'est-ce qu'il y a vraiment dedans, et qu'est-ce qui se passe quand ça va dans le drain?”— Diana Trasente, M.Eng. — Diana Trasente, M.Ing.
The Method
How Sampson Eco Window Cleaner Cleans With Two Ingredients.
Four steps. Water and one plant-derived surfactant. No ammonia, no VOCs, no phthalate-carrier fragrance. Streak-free on cold glass.
Break the surface tension of the oily film
The plant-derived glycoside surfactant breaks the surface tension of the oily film that holds fingerprints, kitchen splatter, and water-spot residue to the glass.
Lift, suspend, carry away
Water carries the lifted soil away from the surface — no propylene glycol carrier, no isopropanol, no ammonia. Glycoside and water doing what they evolved to do.
Evaporate without a film
Both ingredients evaporate. No soap-film residue, no surfactant haze, no streak-forming carrier — the streak problem on glass is solved by removing what causes it.
Wipe and walk away
Microfibre cloth or squeegee finishes the job. No rinse, no second pass. Avoid hot glass in direct sun — the water evaporates before you wipe and leaves a faint mineral mark.

Format Matters
How Eco Window Cleaner Compares to What's On The Shelf
Glass cleaner is the simplest job in the cleaning aisle — water and a surfactant solve it. Everything else on the label is doing something other than cleaning glass.
| Sampson Eco Window Cleaner | Conventional ammonia-based glass cleaner | "Eco" / greenwashed glass cleaner | |
|---|---|---|---|
| Named ingredients on label | 2 (water + decyl octyl glycosides) | 6–12 plus "fragrance" undisclosed | Partial disclosure typical |
| Ammonia | None | Yes (primary cleaning agent) | Sometimes |
| VOC content | None — water-based, no solvent carrier | Variable, often high (isopropanol common) | Sometimes disclosed |
| Cleaning system | Plant glycoside surfactant + water | Ammonia + petroleum surfactant + glycol ether | Mixed |
| Surfactant origin | Plant-derived (coconut + corn) | Petroleum-derived | Mixed |
| Scent | Ships unscented; choose from 20+ natural essential-oil fragrances | Synthetic — phthalate carrier likely | Single "natural" scent, source rarely disclosed |
| Biodegradable to OECD 301D | Yes (disclosed on label) | No | Sometimes claimed |
The format is the difference. Same plant chemistry, same engineering rigor — without the bottle, the water weight, or the synthetic add-ons.
