How to tell whether a homemade cleaner recipe is any good

A cleaner recipe is worth making when you can name who published it, its ingredients do not cancel or react with each other, it claims only what its publisher could show, its measures are clear enough to repeat, and it tells you how to label and store the result. Very few recipes online pass all five. Even the extension publications that pass the first check easily say little about testing, and some include a combination or a germ claim you should drop. The five checks below take a few minutes, and each one is shown with real examples from published extension recipes so you can keep the useful part of a recipe and set the rest aside.

Check 1: Who published it, and what they say they tested

Start with the name on the recipe. A lifestyle blog, a product listing or a social video is a person's own experience. A university extension publication has an author, a publication number and a revision date, which lets you check it and see when it was last reviewed. These are the extension recipe sources quoted on the recipe pages:

Two things stand out in that table. First, the Kentucky and Missouri card sets are adaptations of the Georgia cards, so when all three print the same toilet bowl recipe you are reading one source three times, which is no stronger than reading it once. Second, versions drift. Kentucky's 2010 set includes a card titled "DISINFECTANT" and a lemon, oil and water furniture polish [4]; Georgia's 2012 and 2018 versions have no disinfectant card and use a beeswax polish instead [3][7]. Check the date and use the latest version you can find.

Then look for testing. None of the publications above reports a test of how well its recipes clean, how long they keep, or what they do to surfaces over time. That is normal for household recipe sheets, and it is why the claims a recipe makes matter so much (check 3).

Check 2: Does anything in it cancel out or react

Read the ingredient list for an acid and a base in the same bottle. Vinegar is an acid; baking soda and washing soda are bases. Baking soda and acetic acid react one to one to give sodium acetate, water and carbon dioxide [8]. The fizz is the two ingredients using each other up, which leaves you with less of each in the bottle. Several published recipes combine them anyway:

A canceling pair wastes ingredients. A reacting pair can hurt you. UF/IFAS warns: "NEVER mix bleach with ammonia, vinegar, rubbing alcohol, or other household cleaners;" because "it can result in a chemical reaction that affects your lungs' ability to function" [1]. NMSU adds "NEVER mix chlorine bleach with commercial toilet bowl cleaners" [2], and CDC's rule is broader still: "Never mix household bleach (or any disinfectants) with any other cleaners or disinfectants" [9]. Any recipe that adds bleach to something else, or tells you to "boost" a mix with a splash of another product, fails this check outright. The full list, with hydrogen peroxide and vinegar among the pairs, is on cleaners you should never mix.

Check 3: Does it claim more than it showed

This is where most online recipes fail and where some extension recipes do too. Under federal pesticide law, "Sanitizes, disinfects or sterilizes" is a pesticidal claim, and a product making it has to be registered with EPA [10]. Minimum risk products, the ones exempt from registration under section 25(b) of FIFRA, "may not claim to" sterilize, disinfect, sanitize or kill germs [11]. A recipe printed on a university handout has not been through that process, so a germ claim attached to it rests on nothing a regulator has reviewed.

Examples from the extension sources above:

• Kentucky's "DISINFECTANT" card (2 tablespoons borax, 1/4 cup vinegar, 2 cups hot water) gives no test data and no contact time, and its own directions say to "Use as you would any commercial all-purpose cleaner" [4]. It is not reprinted here as a disinfectant, and Georgia's later versions dropped it [3].
• NMSU's heated vinegar or 3 percent peroxide spray is labeled "to sanitize," with "To be effective, the solution must sit for 10 minutes" [2]. The publication cites no study for that. What the research on vinegar does show is set out on does vinegar disinfect?.
• UF/IFAS bleach solutions for sanitizing, disinfecting and mildew use figures that differ from CDC's [1]. The only bleach dilution to follow is CDC's, explained on making a bleach disinfecting solution.
• Safety claims fail the same way. UF/IFAS says that with homemade products "you can be reassured that your family isn't being exposed to harsh or harmful chemicals" [1], while the same page warns about bleach fumes and lists ammonia and borax as ingredients. What poison center data and ingredient hazards actually show is on are natural cleaners safer?

The rule for your own use is simple: take a recipe for what it cleans, and get germ killing from a product with an EPA registration number on the label. Cleaning, sanitizing and disinfecting explains the difference.

Check 4: Can you measure it the same way twice

Household recipes are written in teaspoons, tablespoons, cups and drops, which is fine for a spray bottle at home as long as the recipe gives an amount for every ingredient. Watch for gaps. Georgia's soft scrubber calls for "enough soap to form a creamy paste," and its tub and tile card lists "white vinegar" and "baking soda or non-iodized salt" with no quantities [3]. UF/IFAS's orange peel cleaner says to "fill with white vinegar" [1]. Those recipes work as methods, and you will get a slightly different mix each time.

Georgia's cards give cup equivalents such as "1 gallon (16 cups)" and spell out their abbreviations, "tsp = teaspoon tbsp = tablespoon" [3], as Missouri's adaptation does [5], which helps. If you want a smaller or larger batch, multiply every ingredient by the same number and change nothing else; any change in proportion makes it a different, untested recipe. If you plan to sell, switch to weights, as described on weighing instead of measuring.

Check 5: Does it tell you how to label and store what you make

A good source tells you what happens after mixing. The extension sources agree on most of it:

• Label it. UF/IFAS: "If you make your own cleaner, always label it" [1]. NMSU: "Label mixed solutions and keep them out of reach of children" [2].
• Keep it out of food containers. UF/IFAS: "Never put cleaners in food containers" [1]. NMSU: "Do not use food containers for storing cleaning products" [2]. The Penn State handout: "Don't store cleaners in reused food/beverage containers" [6].
• Make small amounts. UF/IFAS: "It is best to mix just what you need and use it all" [1]. Penn State: "Make only enough for immediate use if recipe includes perishable items such as lemon juice" [6].

One source contradicts itself here. The same UF/IFAS page that says never to use food containers also says "You can also recycle old milk jugs and reuse canning jars for dispensers" [1]. Follow the stricter rule, because the risk is someone drinking from a container they recognize; bottles and labels for homemade cleaners covers what to use instead and what to write on the label.

None of these sources gives a tested shelf life for a water-based homemade mix. The few storage times printed (NMSU's furniture polish "will keep several weeks" in the refrigerator [2]; Georgia's beeswax polish "will keep for a year" [3]) are the publishers' statements, with no test reported. How long homemade cleaners last explains why no one has a number.

Recipes already put through these checks

Every recipe on the following pages is quoted exactly from its named source, with canceling pairs and unsupported claims pointed out where they occur. Start with the all-purpose cleaner, then move to the job in front of you: glass, scouring, tub and tile, toilets, floors, wood furniture, ovens or drains.
