Preserving Your Halloween Jack o’ Lanterns

With Halloween just around the corner and pumpkins piled up in bins in every grocery store, are you looking forward to carving a jack o’ lantern? It’s a favorite holiday activity that’s just as much fun as an adult as it was as a kid.


Lots of people know Clorox® Regular Bleach2 can be used to help cut flowers stay beautiful longer, but may not know that the same bleach solution can also help keep a jack o’ lantern from getting fuzzy mold and black mildew inside. It’s super easyt! If you’d like to try this, here’s how!

Materials Needed


  1. Measure 3 teaspoons of Clorox® Regular Bleach2 with CLOROMAX®.
  2. Add bleach to 3 gallons of water.
  3. Fill a spray bottle with the diluted bleach solution.
  4. Carve your pumpkin as desired.
  5. Generously spray inside of your carved pumpkin with the diluted bleach solution.

This also works well with mini-pumpkins — I like using them to hold tea lights. You can trace the outline of a tea light on the top of the pumpkin, and then cut around it. The top pops off, and then you can clean out the inside and soak it in the bleach solution as described above. Finally, just pop in the tea light! If you will be using these to set a festive table for a Halloween Party, no worries about prepping them early!
