What does WD-40 do for pumpkins?

Give Your Jack-O’-Lantern a Long-Lasting Glow with WD-40

Fall wouldn’t be complete without a few carved pumpkins grinning on doorsteps and windowsills. But if you’ve ever watched your masterpiece wilt, sag, and mold too quickly, you’re not alone. Carved pumpkins start to dry out and decay almost as soon as the knife hits the rind — that’s just nature. But there’s a clever, lesser-known trick that could extend your pumpkin’s prime: WD-40.

Yes, WD-40 — the same can you use to silence squeaky hinges or free a rusted bolt — can actually help preserve your jack-o’-lantern. After you’ve finished carving, give the pumpkin a light, even spray of WD-40. The formula creates a thin protective barrier that seals in moisture and slows down dehydration and fungal growth, the main culprits behind that sad, shriveled look.

Beyond preservation, the spray adds a subtle shine that makes the pumpkin’s surface look fresh and vibrant — almost like it was just picked from the patch. Some pumpkin artists even swear by soaking their carving tools in WD-40 first to prevent sticking and make cleaner cuts.

Of course, this isn’t a magic fix — your pumpkin won’t last forever. But with a little spritz, you might gain a few extra days of crisp features and that spooky glow. Just remember to use it sparingly and in a well-ventilated area, and avoid overspraying near candles or open flames.

So next time you're perfecting your pumpkin design, don’t forget the finishing touch: a quick coat of WD-40. It’s a simple pro-tip that turns a seasonal tradition into a slightly longer-lasting celebration.
