Most warts can be killed at home with over-the-counter salicylic acid, applied daily over several weeks. The process is slow but effective, and it works by dissolving the infected skin layer by layer until the wart is gone. If home treatment fails after two to three months, professional options like freezing can clear warts in one to three visits.
Warts are caused by HPV (human papillomavirus), which infects the top layer of skin and triggers rapid cell growth. That’s why warts feel hard and raised. Because a virus drives them, simply cutting or scraping a wart off won’t work. You need to destroy the infected tissue completely, or the wart grows back.
Make Sure It’s Actually a Wart
Before you start treatment, confirm you’re dealing with a wart and not a corn or callus. Warts have a grainy, fleshy texture with tiny black dots scattered across the surface. Those dots are small blood vessels that have grown into the wart. Corns and calluses, by contrast, are hard, raised bumps surrounded by dry, flaky skin with no black pinpoints. If you squeeze a wart from the sides, it typically hurts. A callus hurts more with direct pressure on top.
If a growth is pigmented, bleeding, ulcerated, or changing color rapidly, skip home treatment and have a doctor examine it. The same goes for anything on your face or genitals, where over-the-counter products can damage sensitive skin or where misdiagnosis carries higher stakes.
Salicylic Acid: The Most Proven Home Treatment
Salicylic acid is the most studied and widely recommended wart treatment you can buy without a prescription. It comes in gels, liquids, ointments, and medicated patches at concentrations ranging from 5% to 27% for daily-use products. Higher-concentration ointments (25% to 60%) are applied less frequently, every three to five days. For most people, a 17% liquid or gel applied once daily is a good starting point.
The treatment works best when you follow a consistent routine:
- Soak the wart in warm water for five minutes to soften it. A bath or shower counts.
- File the surface with a disposable emery board or pumice stone. This removes dead skin so the acid can penetrate deeper. Use that file only on the wart, nowhere else on your body, because the virus can spread through skin contact.
- Dry the wart thoroughly before applying anything.
- Apply the salicylic acid directly to the wart, following the package directions.
- Repeat daily, filing the wart every few days rather than every session.
This process typically takes 4 to 12 weeks. You’ll see the wart shrink gradually as layers peel away. If you stop too early because the wart looks smaller, the remaining infected cells can regrow. Keep going until the wart is completely flat, the skin lines return to normal, and those black dots are gone.
Does Duct Tape Work?
Duct tape therapy gained popularity after a small study suggested it rivaled freezing. The idea is simple: cover the wart with silver duct tape for five to six days, remove it, soak and file the wart, then reapply fresh tape. The theory is that the occlusion irritates the skin enough to trigger an immune response against the virus.
However, a Cochrane review found that the initial study was too small to draw conclusions from. Two later trials using clear duct tape on 193 participants showed no advantage over placebo. If you want to try it, the American Academy of Dermatology suggests combining it with salicylic acid: apply the acid first, then cover with silver duct tape. On its own, duct tape is unlikely to clear a wart.
Apple Cider Vinegar and Other Home Remedies
Apple cider vinegar contains acetic acid and malic acid, which can exfoliate skin. Some people apply it to warts twice daily with a cotton ball, and Cleveland Clinic notes that after several weeks, you may be able to scrub out or pull out the wart. That said, there are no clinical trials backing this method, and vinegar is acidic enough to cause chemical burns on surrounding skin if you’re not careful. If you try it, protect the healthy skin around the wart with petroleum jelly and stop if you see blistering or significant redness.
Other popular home remedies like banana peel, garlic, and tea tree oil have little to no clinical evidence supporting them. They’re unlikely to cause harm, but they can waste weeks of time you could spend on a proven treatment.
Professional Treatments
If you’ve used salicylic acid consistently for two to three months without results, it’s time to consider a doctor’s visit. The two most common in-office treatments are cryotherapy and cantharidin.
Cryotherapy uses liquid nitrogen to freeze the wart, destroying the infected tissue. Your doctor applies it directly, which feels like a sharp, burning cold. A blister forms underneath and the wart lifts off as the skin heals over the next week or two. Clearance rates range from 39% to 84% at three months, depending on the size and location of the wart. Most common warts need one to three sessions spaced a few weeks apart. Thicker warts on the soles of the feet (plantar warts) often require additional treatments.
Cantharidin is a blistering agent derived from beetles. A doctor paints it on the wart, covers it with a bandage, and within hours a blister forms that lifts the wart from the skin beneath. It’s painless at the time of application, which makes it a good option for children, though the blister can be uncomfortable later. A prospective trial found that conventional treatments like cryotherapy and cantharidin achieved complete clearance in about 70% of treated warts, with partial response in 82%.
Pulsed-dye laser is sometimes offered for stubborn warts. It targets the blood vessels feeding the wart. In the same trial, laser treatment cleared 66% of warts, statistically similar to conventional therapy. It requires the same number of sessions but costs more, so it’s typically reserved for warts that haven’t responded to other approaches.
How to Stop Warts From Spreading
While you’re treating a wart, the virus is still active and can spread to other parts of your body or to other people. The most common way warts spread on your own body is through picking, biting, or scratching. Nail biting and cuticle picking are especially effective at spreading warts to the fingers and around the nails. If you touch or file a wart, wash your hands immediately afterward.
Keep treated warts covered with a bandage during the day. Don’t share towels, razors, or pumice stones. If you have plantar warts, wear sandals in shared showers, at the pool, and in locker rooms. Wet skin on rough surfaces is a prime transmission route. For people who exercise, shared gym equipment (particularly free weights) and grappling sports like wrestling and jiu-jitsu carry higher risk. Wearing gloves and wiping down equipment helps.
Shaving over a wart can drag the virus across a wide area of skin, creating new warts along the shaving path. If you have a wart near an area you shave, work around it or use a method that doesn’t scrape the skin.
Why Warts Come Back
Even after successful treatment, warts recur about 30% to 35% of the time. At least 20% of recurrences happen within the first 12 weeks. This happens because treatment destroys visible wart tissue, but microscopic virus particles can linger in surrounding skin that looks normal. Your immune system eventually clears HPV on its own in most cases, but until it does, the virus can reactivate.
People with weakened immune systems face higher recurrence rates and may need more aggressive or repeated treatment. If you notice a wart growing back in the same spot, restart treatment early while it’s small. Small warts respond faster and require fewer treatment cycles than large, established ones.
