for those using citric acid, vinagar or any type of acid it is corrosive and that's what makes it clean so well.You should neutralize the acid to stop the corrosive action of the acid.
I have used vinegar and water with a drop of dish soap in a five gallon buckets and just agitate by hand once in a while more or less let them soak for an hour or 2. Then they are rinsed and neutralized with baking soda to stop the corrosive action. they come out nice and clean with enough shine for me.
