WD-40 Keeps Pumpkins From Rotting

WD-40 was originally developed in 1953 by a small company called Rocket Chemical Company in San Diego, California. The product was created as a rust-prevention solvent and degreaser for the aerospace industry.

The name "WD-40" stands for "Water Displacement, 40th attempt."

The uses for WD-40 seem to have no end, with new uses being discovered constantly.

From lubrication to rust prevention, cleaning, polishing, silencing squeaks, and much more, WD-40 is something you'll find almost every household because of it's versatility and efficacy.

Now, preserving Halloween pumpkins can be added to the list of uses.


Carving pumpkins for Halloween is a favorite activity for kids and families.

However, often the little ones want to carve pumpkins 3 weeks out from Halloween, leaving the jack-o-lanterns a pile of mush and full of fruit flies by the time October 31 rolls around.

Apparently, WD-40 can help.

From WD40.CO.UK  -

"Did you know WD-40 can be used to repel insects from your pumpkins and keep your pumpkins fresher for longer?

Simply engage the wide spray nozzle and apply a thin layer of the formula all over the pumpkin.

The WD-40 formula is flammable so we don’t recommend using it on pumpkins that will be placed near a flame."

The WD-40 will give your pumpkin some extra shine, and the coating will help the pumpkin last longer while delaying decay.

Be sure not to spray near a lit candle and wipe away any excess liquid with a cloth or rag.
