The dishwasher was stinking the other day, I planned on inspecting it to find out what the issue was. My wife suggested I stop on the way home and 3 packets of lemonade powder drink mix the kind you have to add sugar to. Well I added the powder and ran it thru a cycle. Opened the door and it was like new, all the scale from hard water and the odor was gone. That is my helpful tip of the day.
A very interesting tip. I have hard water (despite my softner) so it seems I run my dishwasher more often then needed because of the smell. What in the lemonade rid it of the smell?
Maybe if you tried different dishwasher detergents. I've never had a smell problem like that. My husband says the detergent ate the original garbage disposal. (That was before I moved in.) He's thinking this one is about to start leaking.
I just put the lemonade powder in the same place as the soap, it smelled like lemonade when it was over. I have well water so I get the hard water deposites, I have used iron out in the past but the lemonade works much better.
