Come down to what, 70 or 65? Either way, shouldn't take long, maybe a few days at the most. I have a tube as well and I've never sprayed it. I just pour a small amount of water in the ends by removing the red cap. I use the cap off the jug of distilled water I have and it works fine. I think spraying is best if you have loose beads in like a bowl or stocking. But to answer your question I don't think it matters, but spraying the outside would probably work best to cover the most beads.
