And the copper are having a reaction? You're losing a very thin bit of copper every washing? I wash wood and copper in the dishwasher. I wash silver, being careful to make sure it does not touch any metal, in the dishwasher. Never had problems. |

Over time my copper bottomed pots got shinier with no effort from me, that's what I found odd. |

have you tried Barkeepers Friend on your Revere Ware? If the black is due to tarnish and not burned on grease this should get the black off, and if you use a little Barkeepers Friend every time you wash your Revere Ware the copper bottoms should stay nice and shiny.
If the black is due to burned on grease you’ll need to use some elbow grease and an SOS or Brillo pad to get it off. I had a complete set of Revere Ware for years and kept the copper bottoms shined every time I used them. I finally sold the set toa co worker and replaced it with Farberware Classic. I love the Farberware because I can put it in dishwasher with no worries. Eddie |

Not sure why the plastic tub would change things, perhaps there is some other variable.
I often run Revere in the dishwasher and the copper generally comes out brighter then it went in. I wouldn't worry about the copper in the dishwasher, pretty hard to hurt it, but the dishwasher does destroy the handles. The thing the dishwasher really seems hard on is aluminum. I have one anodized aluminum skillet that the anodizing has partly been stripped from. I also have a few stainless sauce pans with aluminum layers on the bottom where the aluminum has been dissolved to the point it has regressed noticeably. The attack on aluminum seems worse post STPP, perhaps the late non-phosphate detergents are more alkaline/agressive. |

GE poly tub too. Only change in our case was the Cascade Platinum. |

For those who have had good luck with copper in a DW - do you have a water softener plumbed into your house system? The very few times I've tried a copper item in a DW was with hard water and the results were not good. I no longer have any copper but now have softener plumbed into the house supply and am curious what the results would be.
Wondering if soft water makes a difference with the reaction of the water + detergent + food + materials in the DW. Ben |

Ben, Softened water hear, about 18 grains hardness otherwise so really can't avoid it. Copper always comes out brighter then it goes in.
Not sure if water ph could change anything. By the time the detergent is added it is plenty high anyhow, not sure the water itself would change final alkalinity much. Again I typically wash with a Cascade Platinum pack in the dispenser and a Tablespoon or two of gel on the door for the first wash depending on soil level. |

Permatuf 145º Wash Hardest water, our neighbours' water softeners are set to max, ours (which does not feed the kitchen), too). TSP in every wash load (and no precipitate, not ever in the dishwasher or the washing machine. We, alone on the planet earth.) Finish or Walmart or whatever - with TSP and real hot water and the multi-orbital arm and the outstanding filter system of these classic Potscrubbers, everything comes out spotless. One tablet 'dry' chlorine bleach frequently. Copper which is coming out sparkling and oxidation free is doing so because something is eating the copper oxide(s). I don't wash aluminium in the dishwasher (including 'sandwich bottoms') so have no idea what would happen to it, imagine it wouldn't be pretty. I'm guessing our dishwasher's wash cycle water is very soft and the PH is quite a bit above 7. |

I wonder if it's a combination of local water, detergent choice, and actually the stainless platform of WP dishwashers. (Which includes the KA).
Murando, and I think a few others, have testified (and I've heard off-forum) that WP's current DW platforms can get copper and stainless cookware VERY shiny. It must be something in their wash cycle, like heating profile? Along with water and detergent. It's a nice phenomenon that I've never experienced in my Durawash WPs, nor in any of my GEs. My cookware comes out only 95% clean, which IME is "normal." Proteins seem to leave a powdery film wherever meat touched the pan. But I've never heard of that in a current WP machine, and they polish the metal somehow too. It's a wonderful mystery! |
