Anyone remember that motorized scrubbing bubble spray thing that would mist the shower with a touch of a button when you were done? The refills were mad expensive and it ate through them super fast, but if you bought some generic shower spray and diluted it as a home brew refill it worked just as well.
Mine eventually died and wasn't easy to fix ( I forget why). I've never seen another product like it unfortunately but man, I hardly ever had to clean the shower with that thing.
