My dishwasher is awful and is ruining my dishes by leaving lots of detergent residue on them. I've tried different brands of eco-friendly dish detergent and rinsing agents, but I still get the same results. The machine is just messed up. Lately, I've been hand-washing my dishes to try to rescue them, but the residue is not coming off. Hopefully, I'll be able to get a new machine soon because hand-washing uses more water.
Anyway, what can I do to restore my dishes (including glasses and flatware)?
