Use acetone nail polish remover on a cotton pad
Press the cotton pad onto the nail for a few seconds
Wipe the polish off
Repeat if needed
Wash your hands after removal
Apply hand cream or cuticle oil afterward
For non-acetone remover, hold the pad on the nail longer
For glitter polish, soak the cotton pad and wrap the nail with foil for a few minutes
For polish on skin, use remover on a cotton swab
Avoid scraping the nail surface hard
