Wash and Reuse Sponges instead of throwing them away!

Who does this too? Instead of throwing away your dishwashing sponge/scrubber when it starts to get stinky or dirty just put it in the top rack of your dishwasher when you run a load of dishes and it's good as new. Obviously when the scrubber part wears out it's not much good anymore but if it's still in good shape why waste it by throwing it away when you can just wash it. I'm able to do this several times before it's worn out and no good anymore.
