Natural Cleaner Compatibility Chart

Which natural cleaners are safe on which surfaces? See where vinegar, baking soda and castile soap work, where they cause damage, and what never to mix.

Fine Careful Skip

Never mix in one bottle

  • Vinegar and hydrogen peroxide. Stored together they can form peracetic acid. Use one, rinse, then the other if you need both.
  • Vinegar and castile soap. The acid breaks the soap down, so you get neither a cleaner nor a soap.
  • Baking soda and vinegar. They fizz and cancel. Pick one job for each.

Vinegar is brilliant on glass and will quietly ruin a marble worktop. Baking soda lifts smells out of a sofa and scratches a soft wood finish. The ingredients are simple; the surfaces are not. This chart is the thing to check before you reach for the spray bottle.

How to read the chart

Each cell is one ingredient on one surface, with one of three answers:

  • Fine. Use it for a quick clean. Rinse with water when you are done.
  • Careful. It can work, but dilute it, keep it moving, do not let it sit, and rinse straight away. Try a hidden corner first.
  • Skip. Pick something else. The ingredient etches, stains, swells or dulls that surface.

Pick a surface or an ingredient from the dropdowns to shorten the chart. Choose both and the note under the chart spells out the answer in a sentence. The ratings are about whether the surface comes to harm, not about killing germs; none of the ingredients here is a registered disinfectant.

Why acids and stone do not get on

White vinegar and lemon juice are acids. Marble, limestone and travertine are mostly calcium carbonate, which reacts with acid. The result is etching: a dull, slightly rough patch where the polish used to be. It does not wipe off. Granite is harder and less reactive, but acids strip the sealer that stops it staining, so the chart marks it Skip as well.

Stone wants a pH-neutral cleaner, which in this chart means castile soap in warm water, or plain water and a cloth. The Natural Stone Institute's care guidance says the same, and adds: blot spills quickly and avoid anything abrasive. Baking soda and salt are marked Careful on stone for that reason. A light paste can lift a stain, but scrubbing with it leaves fine scratches.

Wood: sealed is not the same as unfinished

A varnished or lacquered table has a layer between the liquid and the wood. A damp cloth with a little castile soap is fine; vinegar diluted well is Careful, because repeated acid dulls the finish over time. Dry it afterwards. Standing water is the real enemy of any wood.

Unfinished or oiled wood soaks up whatever touches it. Water raises the grain, acids leave pale marks, peroxide bleaches, and baking soda works into the surface and stays there. Nearly everything is Skip or Careful here. For a cutting board or an oiled worktop, a quick wipe with barely damp cloth and a re-oil now and then is the whole routine. Salt and half a lemon is a popular board scrub; it is marked Careful because it does lighten the wood if you leave it.

Metal: stainless steel and aluminium

Stainless steel is the easy one. Vinegar, soap, baking soda and peroxide are all Fine. Wipe along the grain of the brushing, rinse, and dry with a cloth to stop water spots. Salt is the exception: left sitting, it pits the surface, so it gets Careful.

Aluminium reacts with both acids and strong alkalis. Vinegar, lemon juice and washing soda are Skip; they darken and pit pans and trim. Baking soda is a milder alkali, so a quick scrub and a rinse is Fine, but do not soak aluminium in it. If a pan has gone dull, it is cosmetic, and it is still a pan.

Fabric, upholstery and laundry

Baking soda is Fine on most fabric and is the first thing to try for smells: sprinkle, leave an hour, vacuum. Castile soap is a gentle spot cleaner. Salt on a fresh spill pulls liquid out before it sets.

Vinegar is Careful on fabric. In the rinse drawer of a washing machine, diluted by a drum of water, it softens and cuts detergent residue. Neat on upholstery it can leave a ring, and on some dyes it shifts the colour. The same goes for 3% hydrogen peroxide, which is a mild bleach: good on a white cotton collar, risky on anything coloured. Test the inside of a seam first.

For specific marks, stain removal by fabric type goes through what works on cotton, wool, silk and synthetics, and eco-friendly laundry practices covers where vinegar and washing soda earn a place in the wash.

Never mix in one bottle

Three combinations come up again and again in recipes online, and none of them should share a bottle:

  • Vinegar and hydrogen peroxide. Together they form peracetic acid, which irritates skin, eyes and lungs. Using one, rinsing, then the other on the same surface is fine. Pre-mixing is not.
  • Vinegar and castile soap. The acid unmakes the soap. You get a cloudy, greasy liquid that cleans worse than either ingredient alone.
  • Baking soda and vinegar. The fizz is the two cancelling each other out. It can shift a slow drain by force, but as a cleaner you are left with salty water.

And the one that is not on the chart because bleach is not a pantry ingredient: never combine bleach with vinegar, or with ammonia. Both mixes release toxic gases. The Washington State Department of Health has a plain summary of what each combination does, linked below.

Which ingredient for which job

The chart tells you what is safe. This is the short version of what each thing is good at:

  • White vinegar. Limescale, hard-water spots, glass, mirrors, taps, kettles. Dilute half and half with water for general use.
  • Baking soda. Smells, light scouring, burnt-on pans, fridge interiors.
  • Castile soap. Everyday washing-up and surfaces, floors, stone, anything that wants a neutral cleaner.
  • Lemon juice. Same jobs as vinegar, smells nicer, costs more. Same rules on stone and aluminium.
  • Hydrogen peroxide (3%). Whitening grout and white fabric, lifting organic stains. Store it in the brown bottle it came in.
  • Rubbing alcohol. Streak-free glass and steel, sticky residue, ink. Flammable; keep it away from the hob.
  • Washing soda. Grease and laundry boosting. Stronger than baking soda; wear gloves.
  • Table salt. Fresh spills on fabric, a scrub medium with lemon on boards and pans.

Most homes need two or three of these, not all eight. Creating a healthier home, naturally is a good place to start if you are replacing a cupboard full of sprays.

FAQ

Questions about the natural cleaner compatibility chart

Can I clean granite or marble with vinegar?

No. Vinegar and lemon juice etch marble, limestone and travertine, leaving dull patches that will not wipe off, and they strip the sealer from granite so it stains more easily. Use castile soap in warm water or a cleaner labelled pH-neutral and safe for stone, then dry the surface.

Is vinegar safe on hardwood floors?

On a sealed floor, a very dilute solution used sparingly and dried straight away is a Careful rather than a Skip. Over months, though, acid dulls polyurethane finishes. A damp mop with a little castile soap does the same job with less risk. On unfinished or oiled boards, keep vinegar away altogether.

What happens if you mix vinegar and baking soda?

They react, fizz, and neutralise each other, leaving mostly water and a little sodium acetate. The fizzing can push a slow drain clear and it is a fun school experiment, but the mixture is a weaker cleaner than either ingredient on its own. Use baking soda for scrubbing and smells, vinegar for limescale and glass, and rinse between them.

Can you mix hydrogen peroxide and vinegar?

Not in the same container. Combined, they form peracetic acid, which can irritate the skin, eyes and airways. It is fine to spray one, rinse, and then use the other on the same surface. Just never store them mixed.

Does vinegar disinfect?

Not reliably. Vinegar reduces some bacteria on surfaces, but it is not a registered disinfectant and does not deal with many common germs. It earns its place for limescale, mineral deposits, glass and smells. If you need to disinfect, use a product made for that and follow its contact time.

Why does castile soap go cloudy when I add vinegar?

Castile soap is alkaline and vinegar is acidic. The acid breaks the soap back down into its fatty components, which is the white, greasy film you see. The mix neither cleans nor rinses well. If you want both, wash with the soap first, rinse, then wipe with diluted vinegar.

What does "Careful" mean on the chart?

It means the pairing can work if you do three things: dilute the ingredient, keep it moving rather than leaving it to sit, and rinse with water afterwards. Spot-test somewhere hidden first. If any of that sounds like too much bother for the job in hand, choose a Fine option instead.

Will baking soda scratch surfaces?

It is a mild abrasive, so on hard surfaces such as steel, glass, tile and enamel it is fine. On soft or polished surfaces, including marble, lacquered wood, laminate and some plastics, it can leave fine scratches, which is why those cells read Careful. Use it as a loose paste and let it do the work rather than scrubbing hard.

Why is bleach not on the chart?

The chart covers simple ingredients most people already have in the kitchen. Bleach is a different kind of product with its own safety rules. The one thing worth repeating here is that it must never be mixed with vinegar, lemon juice, ammonia or any other cleaner.
