Ever wonder how you can take those pretty pine cones you find in your yard, park, or on walks, and turn them into something you can use in your decor? I’ll show you how you can collect, clean and preserve pine cones so you can use them for years to come.

How to Clean and Preserve Pine Cones

When I lived in Tennessee I used to love to collect things in nature to use in my seasonal decorations–things like fall leaves, acorns and pine cones. When we moved to Texas, it was hard to find those types of things to collect, especially pine cones. We did have the occasional changing tree and acorns, but pine cones were nowhere to be found. With moving to Missouri, I was thrilled to discover a HUGE pine tree in my backyard that dropped massive pine cones just waiting for me to collect.

But, one of the downfalls to collecting pine cones from nature is that they are sticky, dirty and filled with bugs. Yuck. Who wants that in their house? Not me… So that’s why I have the perfect method to clean and preserve your pine cones.

How to Clean and Preserve Pine Cones

What you’ll need

First, collect your pine cones. The best ones to collect are ones that still have a partial stem, no broken wings, and are open. You can collect closed cones, but the open ones are easier to clean (and I think look prettier)

Once you have collected all of your pine cones, you will want to spot clean them. Remove any remaining needles, leaves, etc from the cones. Using rubbing alcohol on a Q-tip, you can clean any really dirty or gross spots on the cones.

Fill up your 5 gal bucket with HOT water about 1/2 way full. Then add 2 cups of vinegar making a 1 cup to 1 gal solution. Vinegar will kill any bugs that are living inside the cones, and will get rid of the sap residue.

Soak the cones in the bucket for 30-45 minutes, moving them around or stirring the bucket every 15 minutes. You will notice that the cones will start to close up as they soak up the water. This is normal.

After soaking, remove the pine cones from the water and let them air dry on a large towel. Air drying can take 2-3 days for the pine cones to fully dry and open back up. If you don’t have that kind of time, you can put them on a cookie sheet and in the oven at 200 degrees for about 30 minutes. Please watch them closely while you dry them though! I prefer the air-dry method personally, plus the pine cones tend to keep their pine scent this way.

Once the pine cones have dried completely, you will want to spray them with some sort of clear acrylic spray. I like using Mod Podge brand, but you can use whatever you have on hand. This keeps the pine cones from becoming brittle quickly. They will eventually, but spraying them with a clear coat keeps them for at least a few seasons. To store the pine cones after the holidays, keep them in a clear plastic freezer bag with as much air removed as you can.

Now that you have clean and preserved pine cones, you can decorate to your heart’s content. I like to decorate with them as is, but you can also make them into pretty ornaments. Check out this great list of 35 DIY Pine Cone Crafts.

I just collectrd a bunch of pine cones today. They are pretty dry on their own. If I don't spray with an acrylic spray will they last thru December?

Hard to say. They may become brittle and break easily. I would still recommend cleaning them like the tutorial because even if they look clean, you'd be surprised at how much dirt and bugs can hide in those nooks and crannies.

I actually used old cookie sheet so the sap doesnt fal into ove & when im drying them after i dip them in paint i put them on waxpaper right onto oven rack. I found they will cose up right after putting them into oven after dipping but then they dry out and open but i put the oven on like 350 to hurry the drying time. It may get a little smoky cause of the paint drying so use your oven fan vent amd have house ventilated and surely do not get sidetracked. But they open beautifully. Wished i could share pic of the blue ones i dipped and not having cleaned sap off the tips turned green and shiny guven them a beautiful sheen.

Thank you for posting this information. I recently moved to the south and pine cones abound! I would love to try and make luminary jars this year using the pine cones but wasn't sure how to clean them. So glad I found your page. Kate
