Nail fungus can be stubborn, unsightly, and frustrating. It often causes yellow, thick, or brittle nails and thrives in warm, moist environments — especially in closed shoes or shared spaces like pools or gyms.

Luckily, there’s a natural remedy that’s affordable, safe, and surprisingly effective: white vinegar.

Here’s how to use it — and what else you should do to get the best results.

1. Clean your nails thoroughly before applying anything

Always wash your feet or hands with soap and water, and dry them completely. Fungus loves moisture, so starting with a clean, dry surface is essential.

2. Apply pure white vinegar with a cotton swab

Dip a clean cotton swab in white vinegar and apply it directly to the affected nail, especially along the edges and thickest areas. Do this twice a day — morning and night.

3. Be patient and consistent

Nail fungus doesn’t disappear overnight. Stick to the routine daily for at least 4–6 weeks. Consistency is key to success with natural remedies.

4. Avoid touching irritated skin

If the skin around your nail is sensitive or broken, avoid direct contact with undiluted vinegar. You can dilute it with a little water (1:1 ratio) before applying.
