Vinegar has a reputation as the all-purpose natural cleaner, but the list of things you should never clean with vinegar is longer than most people think. The acid that cuts through soap scum can also dull stone, wear down finishes and harm rubber.
Here are six things to keep vinegar away from, what can go wrong, and what to use instead. Three should stay vinegar-free. Three come with a catch, so read it before you reach for the bottle.
One important distinction: vinegar can help clean some surfaces, but it isn’t a disinfectant. The American Cleaning Institute says it will not be as effective as an EPA-registered disinfecting product. If you’re trying to kill germs rather than remove dirt or buildup, use a product labeled for that purpose.
Three things to keep vinegar away from
1Marble and granite
Marble is particularly vulnerable to vinegar because it is acid-sensitive. The Natural Stone Institute says products containing lemon, vinegar or other acids may dull or etch calcareous stones, a group that includes marble and limestone. Granite is generally more acid-resistant, but the institute still advises against acidic cleaners because some granite can contain acid-sensitive minerals. If you’re unsure what type of stone you have, skip vinegar and use a stone-safe, non-acidic cleaner.
Do this instead: clean with a neutral cleaner, stone soap, or a mild liquid dish detergent and warm water, as the Natural Stone Institute suggests. If you’re unsure, ask your stone supplier or installer.
2Phone, tablet and computer screens
Don’t reach for vinegar unless your device maker specifically says it’s safe. Cleaning instructions vary, and some makers recommend only a soft cloth, water, screen wipes or specified alcohol-based wipes. Most also warn against harsh cleaners and against spraying any liquid directly onto a screen, since it can drip inside and cause damage. A coated electronic display isn’t the place to experiment with an unapproved household cleaner, so check your manual.
Do this instead: wipe with a soft, dry cloth. For stubborn marks, dampen the cloth with water only, or follow your maker’s guidance on a 70 percent isopropyl alcohol wipe.
3Wood floors and finishes
The National Wood Flooring Association says vinegar’s acidic nature can damage wood floors and their finishes over time, and warns never to leave wood floors wet. Cornell Cooperative Extension says not to wet-mop a wood floor, because standing water can dull the finish, damage the wood and leave a discoloring residue. A vinegar and water mop can bring both problems. The American Cleaning Institute says the same goes for hardwood floors and furniture, and advises checking the manufacturer’s instructions first.
Do this instead: dust or vacuum often, and use a cleaner made for your floor’s finish, following the flooring maker’s instructions. On waxed floors, Cornell says to touch up scratches by waxing the area and to buff heel marks, instead of mopping them.
