Final answer:
Acetone-based nail polish remover is the best type to use on artificial nails.
Step-by-step explanation:
The type of nail polish remover that should be used on artificial nails is acetone-based nail polish remover. Acetone is a powerful solvent that can effectively dissolve the nail polish on artificial nails. It is commonly used in nail polish removers as the chief ingredient. While acetone-free nail polish removers, alcohol-based nail polish removers, and water-based nail polish removers can also remove nail polish, they may not be as effective on artificial nails.
