Put hula hoop down inside container
Use Non-Ultra Blue Dawn (available at WalMart) on top of the (cotton wrapped*) hula-hoop - then I pour water from the garden hose (Fairfax County water is pretty good stuff) all over the hoop. I let it sit for several minutes to soak in. After that, when I am ready, I rotate the hula-hoop once in one direction, then back to its starting position, then I bring the hula-hoop up. sometimes it takes a few minutes and rotations to get the soap working well.
*Cotton-wrapped hula-hoop: I cut up a t-shirt into long strips & wrap then sew it loosely around the hula-hoop. If you wind it too tightly, it will be too heavy to pick up when it's full of soapy water.
