Explore the top 3 home remedies people ask about: apple cider vinegar, hydrogen peroxide, and baking soda. Learn their common uses, risks, and safer options.
You’re making dinner when the knife slips. The cut is small, and you remember the brown bottle of hydrogen peroxide in the bathroom cabinet. Should you reach for it? For a minor cut, the Mayo Clinic recommends rinsing with running water. Hydrogen peroxide can irritate the wound. Mayo Clinic first-aid guidance
That kind of question comes up with apple cider vinegar and baking soda, too. All three are easy to find, and all three turn up in DIY advice. This guide to the top 3 home remedies examines what people use them for, where the evidence falls short, and what you can do instead when you have heartburn, a scrape, a sore throat, or a breakout.

1. Apple Cider Vinegar for Heartburn and Sore Throats
Does apple cider vinegar help acid reflux?
There’s too little research to tell whether apple cider vinegar relieves acid reflux. It’s also highly acidic, and some people find it makes their heartburn worse. Drinking it straight can damage tooth enamel and irritate the esophagus. If you enjoy the flavor, use it as an ingredient in a salad dressing or marinade.

If heartburn usually starts after you lie down, pay attention to when you eat dinner. Leaving at least three hours between your last meal and lying down may ease nighttime reflux. You can also look for patterns in what you eat and drink. For example, if coffee repeatedly brings on symptoms, adjusting that habit gives you something specific to try. If heartburn keeps coming back, bring that pattern up with a healthcare professional. National Institute of Diabetes and Digestive and Kidney Diseases on diet and reflux
Should you drink vinegar for a sore throat?
Evidence for using apple cider vinegar to treat a sore throat is limited. Try warm fluids or a saltwater gargle if you can gargle safely. Both are options the CDC lists for easing discomfort. Seek medical care if symptoms worsen or fail to improve within a few days, and get urgent help if you have trouble breathing.

2. Hydrogen Peroxide for Cuts, Earwax, and Flu
What should you use to clean a minor cut?
Start by washing your hands. If the cut is bleeding, use a clean cloth or bandage to apply gentle pressure. Rinse the cut under running water and wash the skin around it with soap. If the cut needs protection, cover it with a clean bandage and change it daily or when it gets wet or dirty. Leave hydrogen peroxide in the cabinet, since it can irritate the wound. Mayo Clinic first-aid guidance
If dirt remains after rinsing, or if pain, warmth, swelling, or drainage increases, seek medical care. A deep or dirty cut is also a reason to check whether you need a tetanus booster. Mayo Clinic first-aid guidance
Can hydrogen peroxide help with earwax?
A healthcare professional may recommend peroxide drops to soften a buildup of earwax. If your ear feels blocked or your hearing changes, get the ear checked before trying drops. Avoid hydrogen peroxide drops if you have a history of repeated ear infections, a perforated eardrum, or previous ear surgery. Keep cotton swabs out of the ear canal, where they can push wax deeper.

Does hydrogen peroxide prevent the flu?
Keep hydrogen peroxide out of drinks and away from do-it-yourself flu treatments. Swallowing it can cause harm, especially in concentrated forms. The CDC recommends an annual flu vaccine as the main way to reduce your risk of seasonal flu and serious complications. Washing your hands and covering coughs and sneezes also help slow the spread.

3. Baking Soda for Acne, Heartburn, and Household Odors
Is baking soda a good facial scrub?
A rough scrub can irritate acne-prone skin and make breakouts worse. The American Academy of Dermatology recommends washing your face gently with a nonabrasive cleanser. Use your fingertips, rinse with lukewarm water, and pat dry. If over-the-counter products haven’t helped or breakouts are leaving scars, a dermatologist can help you find a treatment.

Is it safe to drink baking soda for heartburn?
Sodium bicarbonate can reduce stomach acid temporarily. Dosing it yourself from the kitchen box adds risks, including excess sodium and rapid gas buildup in the stomach. Poison Control advises using baking soda for stomach upset only under a healthcare professional’s direction. A pharmacist can help you choose an over-the-counter antacid and check whether it fits with the medicines you already take. Poison Control on baking soda
Where does baking soda come in handy at home?
If an odor lingers in the refrigerator, start by removing spoiled food and cleaning up spills. Once the fridge is clean and the smell has faded, an open box of baking soda can help absorb lingering odors. If a household surface needs disinfection, clean it first and follow the directions on a disinfectant labeled for that surface.

Top 3 Home Remedies: Frequently Asked Questions
Can apple cider vinegar treat allergies or sinus infections?
There’s no good evidence to recommend it for either condition. If congestion is the problem, a saline nasal spray is one option the CDC lists for symptom relief with a sinus infection. Contact a healthcare professional if symptoms last more than 10 days without improving or get worse after initially improving. Memorial Sloan Kettering on apple cider vinegar · CDC on sinus infections
Is “food-grade” hydrogen peroxide safe to drink?
Never drink hydrogen peroxide. “Food-grade” can describe a highly concentrated product capable of causing severe burns and other serious injuries if swallowed. If someone swallows it, contact a poison center promptly for advice. Poison Control on hydrogen peroxide
Can baking soda disinfect kitchen surfaces?
Use baking soda for odor control. For routine surface cleaning, the CDC recommends soap or detergent and water. When you need to disinfect, choose a product labeled for the surface and keep the surface wet for the amount of time specified on the label. CDC on cleaning and disinfecting at home
Which Home Remedy Is Worth Keeping?
Keep apple cider vinegar for the salad, baking soda for baking and household odors, and use peroxide ear drops only when a healthcare professional recommends them. For that minor cut in the kitchen, the first thing you need is already at the sink.
