I really try to choose my battles carefully in order to keep a healthy union. I will not engage in an argument over dirty dishes left on the kitchen countertop--once they are left there--even if the dishwasher is empty.
However, if he gets up from the dining table before me and I have an empty dishwasher, I would casually remind him by saying: "hon, can you please rinse them before you put the dishes in the dishwasher?" it does the job all the time!
I know that it is easier said than done but, I truly believe that the only person that can be changed is yourself. And, good habits are harder to acquire than bad ones. Moreover, repetition works as long as you are consistent.
One last thing...men and women, we really are wired differently.
