Don’t Use White Vinegar to Clean These 13 Things


If you spent any time at all poking around household blogs, you’ll quickly realize that plain white vinegar is apparently some sort of miracle substance. Many people claim it can clean basically anything: laundry, windows, floors, bathrooms, mirrors, and more.

With all of this praise, you might start to feel like vinegar first descended to earth in a golden cloud as a gift from the gods! All that said, it’s not as though vinegar is a magic cure-all. In fact, there are some things we definitely should not be cleaning with vinegar. That’s because even plain white vinegar is a pretty strong acid that can corrode or react with many common materials.

  1. Stone Surfaces

    Stone countertops and similar surfaces seem practically indestructible. However, the acid in vinegar is strong enough to cause stains or even eat away the stone surface over time.

  2. Cast Iron

    Many cast-iron-cookware-users talk with pride about the “seasoning” that develops on the iron overtime. It’s actually a layer of oil that keeps the cookware nonstick. Soap is a no-no for cleaning cast iron, since it will strip this seasoning right off. Vinegar has the same effect. Not only that, the acid in vinegar will react with the iron itself, causing it to rust.

    So you definitely do not want to use vinegar to clean your cast iron! Instead, try gently scrubbing the cookware clean with water, a little kosher salt, and a towel.

  3. Irons

    If vinegar reacts with the iron in cast iron cookware, then it stands to reason that it will also react with iron in …. irons. As in the kind you press your clothes with. Some blogs suggest pouring vinegar into an iron’s water reservoir to clean it, but this can damage the metal parts. If you’re worried about deposits building up inside your iron, used distilled instead of tap water.

  4. Carbon Steel Knives

    Vinegar can cause carbon steel to darken and/or become blotchy. Some people like the look of a “patina” on their knives, but if you want to keep yours shiny and new, avoid cleaning them with vinegar.

  5. Aluminum

    Vinegar reacts with aluminum, too. Aluminum won’t rust like iron, but vinegar will give it spots and blotches. I know–I ruined a favorite moka pot after trying to clean it with vinegar!

  6. Touchscreens

    It turns out that smartphones, tablets, and similar devices actually have a coating on their touchscreens that is fingerprint-resistant. Cleaning the screen with vinegar can strip this coating off. Instead, just use water and a microfiber cloth to polish it.

  7. Hardwood Floors

    Most hardwood flooring manufacturers say that cleaning the wood with vinegar will damage its protective and beautifying finish. You might as well just scrub it with sandpaper! Use an approved flooring cleaner instead.

  8. Waxed Wood

    Many cabinets and some other wood surfaces (including some floors) have waxed-based finishes. Keep vinegar away from these for the same reason.

  9. Washing Machines

    The jury’s out on this one. Many people suggest that vinegar is great for cleaning clothes, and can also clean and disinfect a washing machine itself. On the other hand, others say that the vinegar can damage the rubber hoses that connect the washer to plumbing. Check with your machine’s manufacturer if you want to be sure!

  10. Unsealed Grout

    Vinegar can be great at cleaning tiled surfaces, but not if the grout between the tiles is unsealed. Without a protective coating, the grout will become damaged.

  11. Egg Stains

    If you spill egg on something, clothing or otherwise, don’t reach for vinegar. Its acid can cause the egg to coagulate, making it harder to remove.

  12. Tough Carpet Stains

    Vinegar can remove light stains from carpet. Tougher ones, like those caused by grass, ink, and blood will need a stronger cleaner, however.

  13. Anything That Involves Bleach

    When bleach and vinegar mix, they react and create chlorine gas. Not only is the gas poisonous, it creates hydrochloric and hypochlorous acids when it mixes with water. These can ruin clothing or other materials they come in contact with.
