So yeah I've been washing my Calphalon anodized aluminum pot and pans in the
dishwasher as well as my Wusthof knives for years and have never had any
problems. Then I start reading here and everybody's like "ohhhh it will
make the universe explode if you do that." I have a Calphalon pan that's
too big for the dishwasher that I always wash by hand and it looks no
different than the one I stick in the dishwasher nearly every day and I got
them at the same time several years ago. When I wash a quality knife I put
it alone in one of the little utensil compartments so it doesn't clatter
against other objects and I put it point down so the handle isn't super
close to the heating element but other than that I do nothing out of the
ordinary. I put the pots and pans on the top rack. I never use heated
drying. But that's it. I think a lot of people here really tend to
over-pamper their stuff. If you have to baby merchandise you bought from
the store then you should be buying cheaper stuff.
