What Customers Say After the Switch
From greenwash-burned shoppers to allergy households — here's what changed when they swapped in Sampson.
Our shower glass had a hard-water film I could never get off with my old bleach spray. Sprayed this, waited a minute, wiped — the glass is actually clear again. And no fumes in a closed bathroom, which is the part I didn't know I was missing.
Hard-water town. Calcium build-up on the faucets and around the drain was a constant fight. This is the first cleaner that actually dissolves it instead of just smearing it around. Repeat application on the worst spots and it's gone.
I switched the whole bathroom over to Sampson. Six ingredients I can read, no perfume headache, and it ships unscented so I add the eucalyptus oil myself. Soap scum on the tub wipes off easily now.
Works well on tile, the tub, and the toilet. One note: it's acid-based so I had to be careful around the marble vanity top — a quick read of the label would have saved me a spot-test. On everything else it does the job without the bleach smell.
What you're spraying in a small, closed room at close range
Soap scum is a mineral problem. Bleach was never the right tool for it.
Conventional bathroom cleaners are built on bleach or ammonia and a fragrance blend to mask both — sprayed at close range in the smallest, least-ventilated room in the house. But soap scum and hard-water build-up are fatty-and-mineral deposits, not germs; the chemistry that dissolves them is acid. Sampson Eco Bathroom Cleaner is six named ingredients built around citric and lactic acid.
Indoor VOC levels are 2–5× higher than outdoor — up to 10× during cleaning, concentrated in small, poorly ventilated rooms like bathrooms (EPA TEAM)
Phthalates hide under the single word "fragrance" — no disclosure is required, and nearly 100% of people tested carry detectable phthalate levels (CDC NHANES)
Spray cleaning products can be 63–99% VOC by weight — what doesn't land on the surface evaporates into the breathing zone (Aerosol & Air Quality Research)

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
Powered by Acid Chemistry. Engineered by Engineers.
Citric and lactic acid, paired and balanced by Diana and Angelo Diadelfo, M.Eng. — environmental engineers since 2010.
Acid dissolves the mineral build-up
Citric and lactic acid react with the calcium and mineral deposits left by hard water, breaking down the scale that holds soap scum to shower glass, tile, and fixtures.
Chelation keeps the acid working
Sodium citrate binds the hard-water ions in your tap water so the acids aren't spent neutralizing the water itself — they stay available to dissolve the build-up on the surface.
Surfactant lifts the loosened scum
The plant-derived glucoside surfactant and lauramine oxide break the surface tension on the loosened fatty residue, lifting soap scum, mildew film, and rust marks off the surface so they wipe away.
Wipe, rinse, break down
Wipe the surface and rinse anything porous or skin-contacting. The surfactants and acids are water-based and biodegradable to OECD 301D — they break down in wastewater treatment instead of persisting in the watershed.

Format Matters
Three bathroom cleaners, three very different labels
What "bathroom cleaner" actually means depends entirely on the chemistry behind it. Here is the comparison, ingredient by ingredient.
| Sampson Eco Bathroom Cleaner | Conventional bleach/ammonia bathroom cleaner | "Eco" / greenwashed bathroom cleaner | |
|---|---|---|---|
| Named ingredients on label | 6 (full list disclosed) | Partial — "fragrance" undisclosed | Often partial disclosure |
| Cleaning chemistry | Citric + lactic acid (dissolves mineral build-up) | Bleach or ammonia (oxidizer, not a descaler) | Mixed, often weak acid or none |
| Bleach | None | Often the primary agent | Sometimes |
| Ammonia | None | Common | Sometimes |
| VOC content | None — water-based | Variable, often high in spray form | Sometimes disclosed |
| Surfactant origin | Plant-derived glucoside | Petroleum-derived | Mixed; rarely sourced |
| Scent | Ships unscented; choose from 20+ natural essential-oil fragrances | Strong 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.
