If you happen to grow winter squash I kept a variety in my spare room, the last one is still in good shape (spaghetti squash) and nearly 2 years old. I tried something my sister had done, mix a bleach solution ( 10% bleach 90% water ) and wiped the squash all down... I don't to if that's useful or not.
I love information like this. I'm filing this away with the info about rubbing fresh eggs with a light coat of oil and storing them in a cool dry place for up to 9 months.
