Homemade Vinegar Spray, and Where Vinegar Doesn't Belong

Vinegar is the one homemade cleaner almost every kitchen in Texas already has. It's cheap. It cuts soap scum and the white mineral film our hard water leaves on glass and chrome. On the wrong surface, though, it does real damage, and we run into that damage more than you'd think. An etched marble vanity. A dull patch on a wood floor. A cloudy ring on a stone shower bench that no amount of scrubbing will fix.

So below is the recipe, and then the honest list of where vinegar belongs and where it doesn't.

Use these at your own risk, and test a small hidden spot first. A homemade mix doesn't come with a label. The American Cleaning Institute points out that DIY recipes don't carry the safety information printed on a store product, so the care has to come from you.

The basic vinegar spray

Plain white vinegar from the grocery store is strong enough. FDA labeling guidance says vinegar should contain 4 grams of acetic acid per 100 mL, and vinegar that's been diluted with water shouldn't drop below 4 percent. You don't need the "cleaning vinegar" that's sold stronger.

Mix one part vinegar with one part water. That's the same ratio New Mexico State University Extension lists for windows and glass. For a stovetop or backsplash with some grease on it, NMSU's other version uses about half a teaspoon of dish soap, a quarter cup of vinegar and two cups of water.

Put the water in first so the soap doesn't foam over. Label the bottle. Then test it somewhere nobody looks, like the back corner of a cabinet door or the bottom edge of a mirror.

Where vinegar does a good job

• Glass and mirrors. Spray, wipe with a microfiber cloth, buff dry.
• Chrome faucets and fixtures. Moen says a 50/50 blend of vinegar and water can be used for a limited time, then rinsed with water and dried with a soft cloth. A quick wipe is fine. Leaving a soaked rag on a faucet overnight is not.
• Glazed ceramic and porcelain tile walls. NMSU's tile mix is 1/4 cup white vinegar in a gallon of warm water with a little dish soap.
• Soap scum on glass shower doors, and the inside of the microwave.
• Some carpet spills, as a second step. The Carpet and Rug Institute uses 1 cup of white vinegar in 2 cups of water after a mild detergent step, and always tests in a hidden area first.

Where vinegar doesn't belong

This is the part most recipe cards leave out.

1. Marble, travertine, limestone and onyx. These stones are mostly calcium carbonate. The Natural Stone Institute says products with lemon, vinegar or other acids may dull or etch them. Etching looks like a water spot that won't wipe away, because the shine itself is gone.
2. Granite and quartzite. The Institute says these resist acid better but can contain small amounts of acid-sensitive minerals. On any stone counter, we'd use what the Institute recommends, a neutral stone cleaner or mild dish soap in warm water.
3. Wood floors. The National Wood Flooring Association says vinegar's acid can damage the floor and its finish over time. It also warns that a soaking-wet mop pushes water into the seams.
4. Stainless steel appliances. GE tells owners not to use acids, bleach, ammonia or abrasives on its stainless steel. Its fingerprint-resistant finishes rule out vinegar-based cleaners by name. Our stainless steel guide has the soap-and-water method instead.
5. Tile floors, week after week. The IICRC recommends a no-rinse, neutral pH cleaner for routine floor cleaning, because acidic or alkaline cleaners can wear down grout and sealer over time. A vinegar wipe on a shower wall now and then is one thing. Mopping a tile floor with it every Saturday is another.
6. Anywhere bleach has been. That's next.

Never mix these

Three rules, and they don't bend.

• Bleach and vinegar. Poison Control explains that bleach mixed with an acid releases chlorine gas. Vinegar is an acid. So are some toilet bowl cleaners. The gas burns the eyes, nose and throat and can injure the lungs.
• Bleach and ammonia. That combination makes chloramine gas. Ammonia is in some glass cleaners, and it's in urine too, which is why the Missouri Poison Center warns against pouring bleach on pet accidents.
• Hydrogen peroxide and vinegar in one bottle. The Missouri Poison Center says the two form peracetic acid, which is corrosive and irritates skin, eyes and the airways. Pick one for the job.

If a toilet still has bleach cleaner in the bowl, flush a couple of times before any vinegar goes near it. And if someone breathes in fumes, get them outside into fresh air and call Poison Help at 1-800-222-1222, any time, day or night. Our full list is in cleaning products you should never mix.

Does vinegar disinfect?

Not the way most people hope. CDC's home guidance is to clean first, and to disinfect when someone in the house is sick or at higher risk, using an EPA-registered disinfectant or a correctly mixed bleach solution. Vinegar is neither. EPA's Safer Choice program also says homemade cleaners usually don't perform as well as products sold in stores.

That's fine for everyday dust, fingerprints and soap film. For a stomach bug going around the house, grab a registered disinfectant and follow its label, including how long the surface has to stay wet.

Storing your bottle

NMSU's extension guide says to label every container and never put a cleaner in a food or drink bottle. Write "vinegar + water" and the date right on it with a marker. Keep it with your other cleaners, up high or behind a cabinet lock if you have little ones, and away from pets.

The American Cleaning Institute's advice is to put products away right after you use them. Kids find the bottle that got left on the tub ledge, not the one that went back under the sink.
