ya, pail to wash and spinner to spin dry.
what do you mean get rid of the dampness? do you mean can spin dry enough? if so yes, i can spin dry until it like those 800rpm washing machine, no dripping and so hang out to dry
I think every color should be okay. I used the orange nanox version, they can prevent yellowing
