A glass cleaner’s ingredient list is short, going by the five labels we read, at four to twelve entries. Every one of the five lists a glucoside, a surfactant the brands describe as plant-derived. Three add denatured alcohol, which ECOS calls a “plant-derived solvent.” Two list acetic acid, the acid in vinegar. Three of the pages say the cleaner is made without ammonia, and the other two don’t mention it. Four list a fragrance. The lists come from each brand’s own page, and Runlow has not tested any of these cleaners.
What does each ingredient in glass cleaner do?
The brands that state a function give the clearest answer. ECOS lists four ingredients and names a job for each: water as a solvent, denatured alcohol as a “plant-derived solvent,” caprylyl/myristyl glucoside as a “plant-derived surfactant,” and acetic acid as “plant-derived vinegar.” Seventh Generation does the same for every ingredient after water. Decyl glucoside is its “plant-derived cleaning agent,” sodium gluconate a “plant-derived water softener,” citric acid a pH adjuster, and benzisothiazolinone and methylisothiazolinone are each a “synthetic preservative.”
Mrs. Meyer’s, Method and ATTITUDE print their lists without functions. The same ingredient names recur across them. Mrs. Meyer’s and Method both list denatured alcohol and a glucoside right after water. ATTITUDE leads with its glucosides as “5% non-ionic surfactants,” then water and acetic acid.
Which glass cleaners say they’re ammonia-free?
Three of the five pages say so outright. ECOS says it uses vinegar “instead of using harsh ammonia like many conventional window cleaners.” Mrs. Meyer’s says its cleaner is “made without ammonia, phosphates, glycol solvents, parabens, phthalates, or artificial color.” Method calls its cleaner an “ammonia-free formula.” Seventh Generation’s and ATTITUDE’s pages make no statement about ammonia, and their published lists don’t name it.
What about fragrance and color?
Four of the five are scented and list fragrance. Seventh Generation names its “plant-derived fragrances” one by one. Mrs. Meyer’s lists fragrance and three essential oils and ends with “Contains Fragrance Allergens.” Method and ATTITUDE each list “fragrance (parfum).” ECOS sells one scent, “Vinegar,” says the cleaner is “made without synthetic fragrances,” and lists no fragrance ingredient. Method’s list also ends with two ingredients named polymeric blue and polymeric pink, with no function given. Fragrance-Free vs. Unscented, and Why the Difference Matters covers what those label words mean.
What the pages say about streaks
Every page promises a streak-free finish, and none publishes a test of it. Their directions are more specific. ATTITUDE’s FAQ says to use “a clean, dry microfiber cloth” and to “avoid overapplying, as too much product may leave marks.” Mrs. Meyer’s says to wipe “with a lint-free cloth” and that washing windows “on a cloudy day is best,” because sun “can cause wet windows to dry too quick.”

Where this comes from
Every ingredient and statement above comes from the five brands’ own product pages, read on October 20, 2026. Where a brand gives no function for an ingredient, this post doesn’t supply one. Runlow has not tested any of these cleaners, and this post names none of them as a pick.
Frequently asked questions
- What is in glass cleaner?
- In the five lists Runlow read, water, a surfactant called a glucoside that the brands describe as plant-derived, and in three of them denatured alcohol. ECOS describes its alcohol as a "plant-derived solvent" and its glucoside as a "plant-derived surfactant." Two of the five also list acetic acid, the acid in vinegar.
- Which glass cleaners are ammonia-free?
- Three of the five pages say so. ECOS says its formula uses vinegar "instead of using harsh ammonia like many conventional window cleaners," Mrs. Meyer's says it is "made without ammonia," and Method calls its cleaner an "ammonia-free formula." Seventh Generation's and ATTITUDE's pages don't mention ammonia, and neither list names it.
- Does vinegar glass cleaner work?
- Runlow hasn't tested any glass cleaner. ECOS, which lists acetic acid as its vinegar, says vinegar "is effective at cutting grease and grime" and "dries quickly." ATTITUDE lists acetic acid as well and gives it no stated function.
