I was looking for the original post that suggested this but couldn't find it. We have now used baking soda in the open cup and vinegar in the closed cup of the dishwasher for detergent three times - and it is a winner. Everything came out clean and grit free!This one is a keeper.BRidget

I wonder how I can get the water that is coming out of the dishwasher to go into the garden? It seems like such a waste to send it into the water treatment facilities. Same with the clothes washer.
