The way I wash dishes, I don't do any more work than someone who uses a dishwasher, and I save all the money that is used both in water and excess electricity.
Dishwasher users:
1 Pay for dishwasher
2. Pay for any maintenance on dishwasher
3. Pay for electricity used by dishwasher
4. Pay for extra water used by dishwasher
Work (not including work one must do to to achieve 1-4):
Load dishes, detergent, push button.
Unload dishes
Me:
Hot water + salt and sometimes lemon (if I feel like it)
Load dishes into hot water/salt solution
Wait for an hour or so and do something else. My "dishwasher" is running now without any electricity.
Transfer to dish rack with occasional wiping of dish where it needs it. Soaking does most of the work.
Transfer to cabinet/cupboard.
