Dish washer

The majority of houses have a dishwasher.  It is generally accepted knowledge these things are for washing dishes.  Most would not try to catch a razorback with a fishing pole or try to open a beer bottle with a Howitzer anti aircraft gun.  Most!   I have a fancy laboratory dishwasher at work and for a mere $12,000 this stainless steel juggernaut will clean the chrome off of a bumper hitch but the point is you do not put a bumper hitch in a dishwasher. 
The older I get the more particular I become about the loading of a dishwasher.  First lets get one thing straight.  Doing the dishes is not simply loading the dishwasher any more than doing laundry is mostly throwing a bunch of cloths in  the washing machine a pressing start.  Doing dishes involves cleaning the kitchen, emptying the dishwasher, loading the dishwasher with hopefully dirty dishes in an orderly fashion to maximize the cleaning efficiencies.  Engineers have spent decades designing and fidgeting with water jets as well as the soap to ensure we have clean forks and spoons.  What good is a spoon that ends up in the back of the dishwasher, stuck on the drain.  Only really short people can reach all the way back past the pointy things sticking you in the chest to retrieve a fork that somehow jumped out of the silverware tray. 
Lets talk about things that should not go in the dishwasher.  Anything made of plastic except the giant plastic ladle with the flat burned edges from scooping spaghetti sauce out of a frying pan.  Most cheap plastic cups, bowls, and flatware will fly like confetti inside a dishwasher and the bowls and cups fall only to collect soapy water that spills all over the floor when you open the door.   There is a undefinable hunk of plastic stuck in the back of my dishwasher.  This multicolored blob has melted itself in a donut configuration around the center sprayer that is supposed to transport water to the top shelves. 

 Do not put anything made of wood in a dishwasher.  Most wood products are not really wood and it will disintegrate under the heat and moisture.  A wooden spoon is usually several pieces of wood glued together.  A cutting board will become Jenga blocks if you put it in the dishwasher more than once.   A wooden bowl will be fine beaver food after two washings in the Whirlpool Potscrubber II.  I used a freshly autoclaved wooden spoon to scoop clabber off the bottom of a Greek yogurt container.  The dry, open pores of the fine wooden spoon sucked up the fromaticum like a New Guinea bower bird on crack only to become embedded nearly permanently in the crervasses.  After two more washing in the dishwasher, some bleach and a little heat, the spoon was clean.  It was sawdust but it was clean.  I have seen rags, flipflops, car parts, children's stuffed animals and once a cat in the dishwasher.  Rumor has it you can cook tuna or any north Atlantic whitefish in a dishwasher.

As I mentioned earlier with the Potscrubber II, you can put pots and pans in the dishwasher.  Just because something fits in the dishwasher does not mean you should put it there.  My ass once fit in the dishwasher but I never washed it in there.  An average frying pan takes up a third of the space and if you put it on the bottom rack of the dishwasher, it blocks most of the water for the entire load.  Your dishes will not get clean and there will be indistinguishable bits all over you dishes.  I thought the goal of this noisy, heat mongering torture chamber was to clean you dishes.   (and now some really short sentences) So? Yeh! Hmmm.
