All-purpose cleaners: what is in the bottle and what the claim costs

Strip the front label and an all-purpose cleaner is water plus a short list of functional classes. Surfactants let water wet and carry oily soil. A solvent handles what water alone will not dissolve. A chelating agent holds the calcium and magnesium in hard water so the surfactant is not spent on them. An acid or an alkali sets the pH. A preservative keeps the bottle stable, because anything with water in it can grow something. Then fragrance and colour, which do no cleaning at all.

ECOS prints exactly that structure on its own product page, giving every entry a CAS number and a function: water as solvent, caprylyl/myristyl glucoside as surfactant, propanediol as solvent, potassium sorbate as preservative, natural fragrance, denatured alcohol as solvent and citric acid as pH adjuster 3. Read a few lists in that format and the same molecules keep appearing across price points. Decyl glucoside and lauryl glucoside, both sugar-derived surfactants, sit in Method’s all-purpose spray 1, in Mrs. Meyer’s 4 and in the Branch Basics concentrate 7. Seventh Generation uses the closely related octyl/decyl glucoside and labels it, on its own page, as a plant-derived cleaning agent 2.

The differences sit further down the list. Method adds potassium hydroxide and sodium carbonate, which push the pH up 1. Seventh Generation and Mrs. Meyer’s both carry benzisothiazolinone and methylisothiazolinone, two preservatives that recur across water-based cleaners 2 4. Branch Basics goes the other way and publishes a seven-item list with no named preservative and no fragrance, the trade being that its bottle is a concentrate you dilute yourself 7. A shopper who has decided that sugar-derived surfactants are the thing they want is choosing between several bottles that already contain them, and the decision has moved on to something else.

Three formats share the shelf. A ready-to-use bottle is finished cleaner, so you buy the water. A liquid concentrate is the formula with most of the water taken out, and you put it back at home. A tablet takes that to its conclusion and removes the bottle as well: Blueland sells a reusable bottle with two tablets for $16, and each tablet makes 24 fl oz of cleaner 5 6. Branch Basics sells 33.8 fl oz of concentrate for $55 and puts the all-purpose dilution at one part concentrate to eleven parts water 7.

Working that through on the prices the brands publish, per finished ounce of cleaner:

• Blueland Multi-Surface Cleaner: refill tablets from $2.25, each making 24 fl oz, so about 9.4 cents an ounce 6.
• Branch Basics The Concentrate: $55 for 33.8 fl oz at one part in twelve, so about 405 fl oz of spray and about 13.6 cents an ounce 7.
• Method All-Purpose Cleaner, Lime and Sea Salt: $4.59 for 28 fl oz ready mixed, so about 16.4 cents an ounce 1.
• Mrs. Meyer’s Basil Multi-Surface Everyday Cleaner: $4.99 for 16 fl oz ready mixed, so about 31.2 cents an ounce 4.

Two things about that ladder are worth saying out loud. It is our arithmetic on the brands’ own prices and not a figure any of them publishes. And it ignores the entry cost: the Blueland number assumes you already own the bottle, which is $16 with two tablets in it, and the Branch Basics number assumes the dilution is right every time. A concentrate mixed stronger than the label says is not a saving.

Half the products here publish no price on their own pages at all. Seventh Generation, ECOS, Lysol and Clorox all send the shopper to a retailer 2 3 10 11. That is ordinary for brands that do not sell direct, and it does mean the cost side of this category cannot be compared on manufacturer evidence alone.

This is the part of the aisle where the wording on the front is a legal position rather than a style choice. Under US federal pesticide law a pesticide is any substance intended to prevent or destroy pests, and every pesticide sold or distributed in the United States has to be registered with the Environmental Protection Agency before it goes on sale 8. Micro-organisms count. A product that says it kills bacteria is claiming to be an antimicrobial pesticide and needs the registration to say it.

EPA defines antimicrobial pesticides as substances used to destroy or suppress the growth of harmful micro-organisms such as bacteria, viruses or fungi on inanimate objects and surfaces, and it separates two grades of claim. Disinfectants destroy or irreversibly inactivate infectious fungi and bacteria, though not necessarily their spores. Sanitisers reduce, but do not necessarily eliminate, micro-organisms to levels considered safe 9.

A cleaner claim needs none of that. Lifting soil off a surface is not a pesticidal claim, so a plain cleaner carries no registration number, no organism list and no contact time. It is why the label of a cleaner is quiet and the label of a disinfectant is dense.

The two mass-market bottles here show the shape of it. Lysol Multi-Purpose Cleaner Simply states that it kills 99.9 percent of bacteria and instructs the user to apply the product and leave the surface wet for five minutes to sanitise 10. Clorox Clean-Up Cleaner plus Bleach states that it kills 99.9 percent of bacteria and viruses on hard, non-porous surfaces 11. Both are making a claim the other six products here do not make. Neither product page prints the registration number that backs it, and both send the reader elsewhere for the ingredient list.

There is a real trade inside that. Five minutes of wet contact is a different job from wiping a worktop, and most days most surfaces do not need it. Where a household does need it, the registered claim is the only thing on the label that says the product has been through the process.

Four of the eight print the full list on the product page itself. Method and Mrs. Meyer’s give the list plain 1 4; Seventh Generation and ECOS add a function to every entry, which is the thing that turns a list into something a shopper can read 2 3.

Blueland publishes its list, but on a linked view rather than in the body of the page. The product page carries the free-from claims, the certification stack and a link marked View all ingredients 5. Lysol’s page carries no list and points to a safety data sheet 10. Clorox’s page carries no list and points to a SmartLabel entry 11. In every case the information exists somewhere; what differs is the number of clicks between the shopper and it, and how many of those clicks land on a document written for a warehouse rather than a kitchen.

The marks are worth separating too, because they answer different questions and are easy to read as one endorsement. EPA’s Safer Choice label, carried here by Seventh Generation and ECOS, is a formal standard covering the safety criteria a product and its ingredients have to meet 12. Leaping Bunny, carried by most of the lower-tox entries, is about animal testing and says nothing about what is in the bottle. Blueland stacks Safer Choice, Cradle to Cradle, Leaping Bunny, B Corp and Climate Neutral on one product page 5, which is the heaviest set here and still does not tell you the ingredients without a further click.

• Whether the full ingredient list is on the page you are reading, one click away, or absent.
• Whether each ingredient carries a stated function. ECOS and Seventh Generation do this, and it is the difference between a list and a disclosure 3 2.
• Whether the front of the bottle makes a germ claim. If it does, the product is a registered pesticide and comes with a contact time you have to honour for the claim to mean anything 8 9.
• The price of a finished ounce rather than the price of a bottle. A ready-to-use spray is mostly water and you are paying to ship it.
• What a certification certifies. Safer Choice is about ingredient safety criteria 12; Leaping Bunny is about animal testing; neither is a statement about how well anything works.
• Whether you will realistically dilute a concentrate at label strength, every time, for the life of the bottle.

Nothing here has been washed, wiped or measured. No cleaning test has been run for this page and no product above is ranked against another, because the evidence used is what the manufacturers publish and that is not the same as knowing how a surface comes up. What the published pages do settle is narrower and still worth having: what is in the bottle, what the claim on the front commits the maker to, and how much of the price is water.
