There are a lot of things you can clean with vinegar, but it is not a miracle all-purpose cleaner. Be careful when using vinegar to clean these:
1. Granite, marble, and stone countertops and floors
Vinegar can damage and etch natural stone. Use water or a stone cleaner on your stone surfaces.
2. Hardwood floors and wood surfaces
Vinegar’s acidity can damage hardwood floors and wood surfaces. Remember also to not use too much water or cleaner when you mop hardwood floors.
3. Unseal grout
Just like stone surfaces, vinegar can weaken and eat away grout that are not sealed. Seal the grout before you use vinegar on it.
4. Computer monitor or smartphone
Some devices have a oleophobic coating that is used to prevent fingerprints. Vinegar would strip away this coating. Use a microfiber cloth to clean your electronic screens.
Vinegar can dissolve pearls. Just use a damp cloth to wipe your pearls to a lustrous shine.
6. Egg stains or egg spill
Eggs and vinegar mixed together would coagulate. You would be making a bigger mess. Just clean up the egg spill with a damp cloth and sanitize.
7. Cast iron and aluminum pots
Vinegar may corrode your cast iron and aluminum pots. If you insist on using vinegar to clean pots and pans, use it exclusively on stainless steel and enameled cast iron pots.
Things you should keep in mind when using vinegar:
1. As a disinfectant or to kill mold and mildew
Vinegar is only a mild disinfectant. It kills some germs and bacteria, but not all. If someone is sick in your household, it is better to use a disinfectant that kills 99.99% of germs and viruses.
2. To kill mold and mildew
Vinegar can only kill up to 82% of mold. Vinegar can fix small mold problems. If you have a bigger problem on your hand, you might want to use something else.
3. To kill pests or weed
It might not be wise to use vinegar to kill pests or weed on plants. Vinegar is a known weed killer so it might also harm the plants that you are trying to protect.
