         | There are four viable takes for why not to put chef knives in
         | dishwashers...
         | 
         | 1) It can be dangerous for anyone reaching into the dishwasher
         | not expecting to find a sharp knife. If you live alone and no
         | one else reaches in there and you're always at maximum
         | vigilance, you do you. But I've known two people who got their
         | hands and wrists sliced open horribly by sharp dishwasher
         | knives.
         | 
         | 2) Every stainless steel kitchen knife I've ever seen where the
         | person regularly put it in the dishwasher had an edge that was
         | so etched and eaten away that it basically looked serrated.
         | Sample size is probably 20 for those. Knives I've seen where
         | the person never put them in the dishwasher may have had a few
         | dings and nicks, but they never looked like their edges were
         | being dissolved away. Note though that this isn't necessarily a
         | bad thing if you don't have an emotional attachment to the
         | knife. A serrated knife is basically sharp on its own for free
         | without sharpening.
         | 
         | 3) Even if the blade isn't appreciably harmed, the rest of the
         | knife made of other materials can be, and the handle could
         | crack, loosen, or weaken. This depends on how the handle is
         | made and attached.
         | 
         | 4) Fancypants non-stainless steel knives do exist and will
         | rust. (see e.g.
         | https://www.reddit.com/r/Bladesmith/comments/bj63yu/this_is_...
         | ) I don't really get why anyone likes them though.
        
           | athenot wrote:
           | 5) The knives can cut the plastic coating on the dishwasher
           | tray/rack and then the inner metal starts corroding. Don't
           | ask how I know...
           | 
           | As for your fourth point, soft metals sharpen in a few
           | seconds. My high carbon steel knives will slice right through
           | tomato peel without smashing the tomato itself; or cut raw
           | meet in one quick movement.

           | 
           | The non-stainless alloys will have an easier time taking and
           | keeping a very sharp edge. This makes them more useful, and
           | for longer. Not only does a very sharp edge make the knife
           | easier and faster to work with, is safer to use than a not-
           | so-sharp knife.

       | They didn't mention the most important tip: Most dishwashers draw
       | from the hot water tap and then use the first ~gallon that comes
       | out for the crucial first scrub, regardless of what temperature
       | comes out the pipe.
       | 
       | Thus, you'll get much better results if, right before pressing
       | Start, you run the kitchen sink's hot water tap until it gets
       | hot.
       | 
       | Second best tip: Spill a bit of detergent outside the detergent
       | box so the initial scrub gets some soap. (The rest gets released
       | in the secondary wash cycle.)

         | 
         | Many (most?) dishwashers have a special section for putting
         | soap that gets used in the pre-rinse cycle. In mine it would be
         | functionally identical to spilling some extra detergent, but
         | it's easier to consistently measure the right amount.

           | True; we use a measuring spoon anyway to scoop 1 tsp into the

             | Ya, I think the same is true in America. Most residential

             | too. But while the EWG does some OK work, they also do a
             | lot of fearmongering, and you can plainly see it in this
             | link. Look at the three big scary red "F" items.
             | 
             | The first scary red "F" is sodium hypochlorite. This is
             | ordinary bleach. EWG cites two reasons for the big scary
             | "F". The first is aquatic toxicity. This is a badly
             | misplaced fear. Consider the fact that chlorine is the most
             | widely used disinfectant in municipal water systems, in the
             | form of hypochlorite and chloramine. Chlorine is dumped by
             | the ton into the water that comes out of your taps and goes
             | down your drains. The extra chlorine from dish detergents
             | is insignificant compared to this and other sources such as
             | laundry bleach.
             | 
             | Also under the chlorine entry, EWG lists a few organic
             | chlorine compounds. This is very misleading. Detergents
             | don't contain any of these chemicals. Rather, they can
             | _possibly_ be generated when free chlorine is added to
             | water containing a lot of organics. Many organohalogens are
             | indeed toxic, but by far most of them that you 'll
             | encounter are generated by municipal water treatment
             | systems. You drink and bathe in water that contains random
             | organohalogens every day, by virtue of the chlorine used in
             | municipal treatment. The small extra quantities generated
             | in your dishwasher aren't a threat to you unless you make
             | it a habit to drink the exhaust water.
             | 
             | The second scary red "F" on their list is zinc carbonate.
             | This is absurd. They say it's primarily because of its
             | potential effects on aquatic life, which I suppose might be
             | a consideration if someone tries to use dishwasher
             | detergent to clean a fish tank. The second reason is
             | "general systemic/organ effects". This is the _really_
             | absurd part. Zinc is an essential mineral in the human diet
             | in large quantities. In very high doses over time, excess
             | zinc can cause problems, but such large doses have nothing
             | to do with dishwasher detergent residues. You 'd have to
             | actually eat large quantities of detergent daily for a long
             | period of time, and even that would be unlikely to cause
             | zinc overdose because the carbonate form has low
             | bioavailability.
             | 
             | The third scary red "F" is "colors". They don't say what
             | the colors are, or why they would be more of a concern than
             | in any other cosmetic or cleaning product.
             | 
             | The fourth scary red "F" is "stabilizer". They don't say
             | what the chemical is, so there's no way to know whether
             | it's any less bullshit than the first three, or even if it
             | exists in the product.
             | 
             | The scary orange "D" items continue the absurdity:
             | 
             | - Nitric acid: I think EWG is confused here. Nitric acid
             | would be used only in minute quantities to adjust pH.
             | Dishwasher detergents are very alkaline, so it's not
             | possible for nitric acid to remain in a liquid product.
             | 
             | - Fragrance: Welcome to life. Everything is scented. I hate
             | it, but putting a scary orange "D" next to it should make
             | you roll your eyes in light of the other fragrances that
             | saturate thousands of other products that don't get rinsed
             | away, and thus stay in the air around you.
             | 
             | - Polyacrylates: you know where else you'll find
             | polyacrylates? Fucking everywhere. Nearly every liquid
             | cosmetic product you'll find uses polyacrylates. Shampoos,
             | hand soap, dish soap, etc. All baby diapers are now filled
             | with polyacrylates. They're added to potting soil to
             | increase moisture retention. Don't eat too much of the
             | solid form because it can expand in your stomach and cause
             | bloating and possibly blockage, but tiny amounts of them
             | are not the least bit threatening in your dishwasher.
             | 
             | In summary, don't blindly trust the EWG. None of these
             | ingredients is the least bit dangerous _even if_ they
             | remained in significant quantities on your dishes, which
             | they don 't.

               | how clean and sustainable this particular corner of
               | industry is.
               | 
               | Did you know that chlorine bleach (such as Clorox) has a
               | shelf life for this reason? It's because hypochlorite is
               | unstable, and eventually that bottle of Clorox will

               | 
               | Not at all. What I'm saying is that dishwasher detergent
               | is one of the cleanest, most harmless (to us and the
               | environment) cleaning products we use. It's actually kind
               | of a miraculous substance; it allows a simple machine to
               | perform the hardest household cleaning job reliably and
               | quickly using very little water or energy. It manages to
               | this with no surfactants (such as phosphates, which
               | actually are environmentally damaging) and no volatile
               | grease cutters. The grease is removed only with alkaline

         | A quick search says faucets run between 1.5 to 2 gallons per
         | minute. That works out to 13.2 to 17.6 minutes of water.
         | Dividing that by 144 items works out to 5.5 to 7.3 seconds of

           | 
           | If you want to save a bit of water, you can get faucets that
           | are "touch" controlled (on/off). That way you can touch the
           | faucet with your wrist/forearm/back of hand to turn it
           | on/off. Temp is controlled by the knob position so it stays
           | the same temp through on/off cycles until you move the knob.
