What I can say for hand - washing, though, is that the best way (speed &
water-wise) is to fill a small dishpan partway with
water, pile in as many dishes as are covered at once, turn off the faucet, take them out one by one,
scrub each side with a soaped sponge or brush, pile up elsewhere, and then rinse the whole pile quickly
under water about as
hot as you can take it.
I simple stick it in the bathtub
under hot water and
scrub lightly with a soft bristle
scrub brush and it looks as good as day one.
