Applying petroleum jelly (Vaseline) to your jack-o’-lantern will help it last longer by creating a barrier that locks in moisture and prevents it from drying out and shriveling. It also helps slow mold growth and can give the carved edges a polished appearance.

How to apply Vaseline

Clean the pumpkin: After carving, you can start by soaking the pumpkin in a diluted bleach solution to kill bacteria and mold. Be sure to let it dry completely.

Apply the Vaseline: Smear a generous amount of petroleum jelly on all the cut edges and the inside of the pumpkin.

For extra protection: Some people recommend doing a bleach soak and then a Vaseline coating for double the benefits.

Be careful with light sources: If you use Vaseline, you must use a battery-powered light, an LED, or a glow stick instead of a real candle, as petroleum products can be flammable.
