The article says storing in the spinner is problematic because of space and of being able to use the spinner for other things. But analyze WHY it works. It gets the greens fairly but not entirely dry, and allows the sealed-in air to circulate under and around the leaves. So, how about using a steamer basket or strainer inside a sealable container or plastic bag? Worth a try. I would put a damp paper towel beneath the basket but not touching it.
