Place your pinecones in a large bucket, and then fill with enough bleach mixture to cover the pinecones. Use between a 1:1 ratio with one part bleach to one part water, all the way up to 2 parts bleach to 1 part water, or somewhere in-between.

Put something over your pinecones to weigh them down and hold them in the bleach water solution, since they float, like a cutting a board with a few rocks on top.

Let sit, outside or in the garage, you want it to be in a well ventilated area. Leave the pinecones in the beach solution for about 24 hours. After one full day in the bleach solution, don’t worry if the pinecones still look kind of dark and are closed up. The pinecones naturally close up when they are in water. Once they're removed from the bleach bath and they dry, the pinecones will open back up and as they dry they'll look lighter.

The next day, drain the pinecones and rinse them with water a couple of times to remove all the bleach.

Next place them on a parchment paper lined baking sheet in a single layer for the drying process. To dry out the pinecones place the baking sheet in a 200 degree oven for a few hours until the pinecones are open again and they look dry.

Lastly, place pine cones in a ziplock bag and add some essential oil -any scent you like we used apple pie. Seal the bag and let them sit a few days or up to a week. When you open them up all the bleach smell will be gone, and they will smell like your oil.
