I’d like to say that of all the bizarre, messy, fragrant things that have taken place in my kitchen, this ranks up there among the weirdest. Last night the house smelled like a mortuary that just happens to be on a Christmas tree farm. Mike didn’t even bat an eye. He seriously only inquired about what I was doing after my pine cones had been in the oven for a couple of hours (I forgot about them!) and even then it was simply to say, “Do you remember about these pine cones in the oven?”
Now, why was the fruit of the beloved pine tree hanging out in my oven?
THIS IS WHY!
Nope, I needed to find a way to de-bug, disinfect and otherwise sterilize the pine cones before I could ever consider making something from them. I consulted a few tutorials here and here and then devised my own grand plan.
I needed my pinecones to be dry asap and I also needed them to be open fully. (Who knew that when pine cones soak in water, they close up?! Not this Colorado mountain girl.)
How To Clean Pinecones
1. In a sink or large bowl, mix 1/2+ cups of white vinegar with water. Soak your pine cones for about 30 minutes. Clearly, this is not exact pine cone science, so just take them out after a little while. Avoid leaving them in for a super long time because they’ll totally close up.
3. Spread them on a foil-lined cookie sheet and bake them at 300 degrees. For how long? Well, until you remember they’re in there. 🙂 Just kidding. I needed mine to bake for 1-1.5 hours to dry and bloom again. I baked one batch for too long and those pine cones sort of over-bloomed. They look like inside out, bedraggled soldiers who just want to be sent back to their happy forrest life. I also noticed that if the pine cones bake too long, they end up brittle. Just take them out of the oven when they’ve sufficiently opened up, but don’t let them linger past that sweet spot.

September 7, 2016 at 7:47 amThank you for this cleaning lesson. This style of pine cone is my favorite to craft with. Do you happen to know the name of these pinecones: what tree they are from? I have a hard time finding them in my area. Mostly long, white pine cones are around me. Thanks!

September 10, 2016 at 4:15 pmThat’s a great question, Beth. I was actually wondering this the other day. I’m not sure what these are called. I’ll be sure to update the post with the pinecone name if I find it out though.
Happy crafting!

December 1, 2016 at 3:10 pmI’m so bummed. I did this and out of the oven they feel soggy and closed. ?

December 1, 2016 at 3:13 pmYa know, I’m thinking of upping the temp to 225 and after this next “batch” of cones, I will put these back in. Also I read to put them in the 300 oven for 30 minutes…… maybe longer on the as well?
gahhhhh I hope these work – I wanted to paint them tomorrow. ?

December 1, 2016 at 5:05 pmHey Karen,
Yeah, I think you could up the temp a bit or just leave them in longer. I def made the mistake of leaving them in too long the first time, thinking that more was just better and they ended up too brittle. I think it has a lot to do with your climate, how wet they were to begin with, etc. But I think if you keep them in a bit longer and check on them frequently, you should def have something paintable by tomorrow. 🙂
Good luck!

December 18, 2016 at 11:49 amMine have just had a second wash and baking – the first was in white vinegar but they still looked dirty. They have also air dried for over a week but ….. quite a few of them went really soft and seemed to be rotten? How can i get that lovely natural /clean looking pine cone colour?
Jess @ Make and Do Crew
December 19, 2016 at 4:05 pmHey Julie,
I’m sorry you’re having trouble! Do you live in a fairly humid climate? I live where it’s quite dry, which could explain why mine crisped up so quickly. If you have more pinecones to experiment with, you might try soaking them for less time. Also, I think more time in the oven, as long as it’s on a really low heat, could help too.

June 25, 2017 at 10:35 amDo you think I can use apple vinegar?
Jess @ Make and Do Crew
June 25, 2017 at 9:18 pmHmm. I would think so! Apple cider vinegar is pure magic in my book so I would guess it would work great for this. 🙂

Do you know if this cleaning process also removes the sap? I cannot handle them without getting sap all over my hands thanks mary
Jess @ Make and Do Crew
December 8, 2017 at 3:10 pmHmmm. Good question! I’m not sure about that. I did notice when I worked on this that some of the sap sort of “cooks out” in the oven. Might be worth just trying it with a couple to see what happens. 🙂

February 9, 2018 at 11:54 amJust looked this up to use in cleaning the pine cones I got for free in the woods. I hope and it looks like the ones I purchased on line and in the craft store are clean. I have been keeping them outside just in case.. So thanks for all the great tips.

July 31, 2018 at 10:53 pmI’m just doing the huge sugar pine cones- I have a few 16″ long !! I washed em in warm vinegar water for 1/2 hour then baked them starting at 200, then gradually up to 300 for an Hour- Mine aren’t losing the copious amounts of sap, even after an hour ?? They also haven’t reopened ?? I live in very dry climate ??
Any thoughts appreciated. Thx Dave

September 15, 2018 at 10:01 amI put the pinecones in the over for 30 min and the horrible smell took over my house! When I opened to oven to take them out the fragance of the cones burned my eyes! I think I’ll just stick to buying them at Ac Moore.
