You have to them dry or they will not keep. I generally spread mine in the shade outside so they are not touching. Do not wash them!!! After drying, I put them in a container where the can breathe ( I use a plastic tub that is a very large weave for better air) and store in a cool dry place. I also put some in the refrigerator cause I like to eat fresh onions. Been doing this for years. If you don’t allow them to dry properly, they will get hot mushy spots and not store well at all.
