Here's why:
* Extremely Flammable and Unpredictable: Nail polish remover is highly flammable, but it's not designed to burn in a controlled manner like lighter fluid. It can ignite very quickly and unpredictably, causing a dangerous and potentially explosive situation.
* Different Chemical Composition: Zippo lighter fluid is a refined petroleum distillate with additives to control its burning properties and minimize soot. Nail polish remover typically contains acetone, ethyl acetate, or other solvents that burn differently and can leave harmful residues.
* Damage to the Lighter: The chemicals in nail polish remover can corrode or damage the wick, cotton packing, and metal components of the Zippo lighter, shortening its lifespan and affecting its performance.
* Health Risks: Burning nail polish remover can release toxic fumes that are harmful to inhale.
Always use genuine Zippo lighter fluid (or a compatible lighter fluid designed for refillable lighters) in your Zippo. It's specifically formulated to burn safely and efficiently in the lighter.
