Storing butternut squash

So much of what I do feels like trial and error. I harvested the last of my butternut squash and hope I prepared it well for storage. After cutting from the vine I washed them and let them dry overnight. Hesitantly I made a weak bleach and water solution and I dipped them in briefly and dried the off. I wanted to kill any remaining mold or fungus spores but I was concerned about food safety since these were grown organically. As I write this I realized that vinegar might have been a better choice. I made shelf space available for a few months storage. The shelves will allow air flow and the squash are not touching one another. I hope this is successful 🙂
