How to Remove Mosaic Warts

Updated March 23, 2017

Warts are the result of skin cell growth error caused by the human papilloma virus. There are different types of warts, resulting from different strains of the virus, and one of the most difficult to remove, according to Podiatry today, is the mosaic wart, which forms in clusters. You can attempt removing mosaic warts with DIY techniques, such as acid treatment and immune-system boosting topical creams, but often surgery will be necessary.

Clean the affected area using soap and water.

Soak the affected area for five to 10 minutes. You can take a bath or shower to complete Steps 1 and 2 easily. The water removes the sebum, a natural body oil, and will allow the acid to penetrate deeper into the wart.

Pat dry the affected area. The area can remain damp, but not dripping.

Apply the salicylic acid to the affected area. Usually the kits come with a brush or other sort of applicator. Cover the entire area of the wart with this liquid.

Sand away dead skin before applying the treatment again the next day. You can use a piece of sandpaper, a nail file, or a pumice stone to do this, according to Family By removing the dead skin this way, the acid is once again able to penetrate the wart with greater ease.

Clean the affected area with soap and water.

Soak the affected area for five to 10 minutes.

Pat dry the affected area.

Apply an immunotherapy cream to the affected area. Podiatry Today recommends immunotherapy when it appears that the prevalence of mosaic warts is due to a lacking immune response to HPV. Recommended topical creams are imiquimod cream, cimetidine or vitamin A.

Sand down the dead skin before the next treatment. Treatments vary but may require application every two days or so.


Mosaic clusters can be difficult to treat yourself, and you may need to visit a dermatologist to assist in chemical treatments or even consider laser surgery. Doctors can also prescribe an injection of immune-system boosting vitamins if the topical creams are not strong enough. If you notice warts reappearing, treat them as soon as possible, as they are easier to eliminate when they are smaller and also less likely to spread, since the disease spreads by contact with the warts.


Removal of warts may lead to permanent scarring. This risk increases with the size of the wart.
