Nope. Would do just as you have said.
I'm not gonna throw in 2-3 items in the machine. Waste of time, water and hydro. And I'm sure if your hydro is the same, but we have a new system where it costs diff amounts based on the time of day. So, I def would not be doing it during the high time.
Same here - I don't even have time sometimes to rinse it off! It gets thrown into a plastic bag, and sits outside until pick-up.
