What is the recommended solvent for removing old nail polish?

The recommended solvent for removing old nail polish is acetone. Acetone is a powerful solvent that effectively breaks down the compounds in nail polish, making it easy to remove. This quality makes it particularly effective on a wide variety of nail polish types, including long-wear and glitter formulas that might otherwise be difficult to remove.

While alcohol can help in some situations, it is generally less effective than acetone for tackling stubborn nail polish. Water and oil are not suitable choices for nail polish removal. Water does not dissolve the ingredients in traditional nail polish, and oil may only soften it slightly but is not effective for complete removal. Therefore, acetone stands out as the most reliable option for this purpose.
