actually, I wash first with dawn dishsoap then with the blue correcting shampoo from Debbie. Yes, I let the piece sit folded up in the correcting shampoo slimey soapy suds on the edge of the bathtub while I shave and 15 min later plunk it in a sink of cool water, swish it around and then a little more rinsing and towel squish roll-up dry apply tape and....whackamadoo...hair...sham wow!
