Do Dishwashers Really Clean Dishes

Some people do enjoy cooking but what most people don’t enjoy is washing the stack of pots and plates lying in the sink.

Hand-washing your dishes usually eat up a lot of ties, it takes an effort, and being in constant contact with chemicals from your dish soap is also not a good thing.

And in this situation, many people prefer to have a dishwasher. In this way, they save much of their time and let the dishwasher do the work.

But the question is do dishwashers really clean the dishes? One more thing that comes to mind is which is the better dish cleaning method dishwasher vs. hand washing which cleans better.

And which choice is friendlier to the environment? Let’s put some light on these questions and discuss them in detail.

Gone are the days when people used to spend the day scrubbing grime from their disgusting kitchen. Now within no time, the dishwasher does in fact clean more dishes.

When it comes to clean dishwashing it’s certainly very functional in sanitizing dishes and other household items, it is very effective in removing bacterial matter and soiling through a combination of temperature, water distribution, and time and that’s not possible with hand-washing.

Almost all Energy Star-certified dishwasher usually gets the water temp to at least 140°F (60°C). That temperature in the sink is too much for your soft mitts and can burn them. 

But you can wear rubber mitts also to get the job done, most water heaters today are capped at 120°F (48°C).

For the actual sanitization of dishes, the National Sanitization Foundation (NSF) has stated that our home dishwashers need to reach a final rinse cycle of at least 150°F (65°C).

The water inside our machines gets hotter compared to the water from our tap, by this way it offers a better chance of killing germs.

In the primitive days when there were not many facilities at hand, people had to carry the water in a cream can from their well, heat it on the stove, and then use that same water to wash all the dishes for a family. And maybe, at that time they were not using more water than a dishwasher.

Today people usually use too much soap and way more water than required and sometimes they also use a sprayer and the water pressure to rinse.

So people use more water in hand-washing per dish and per load than packing the dishwasher. And more importantly, dishwashers generate fewer greenhouse gas emissions.

The extra water distribution and energy need to heat the water for hand-washing is just a little bit too much for the environment.

So if you wash 4 loads of dishes every week with 8 place settings per load over the course of 10 years, using a dishwasher would generate less than half of the greenhouse gas emissions as compared to hand-washing.

So the dishwasher method is more effective and more hygienic and also better for the environment.

But the question here is: Should you rinse the dishes before they go into the dishwasher? There are some people who hand wash the dishes and then put them.

More than 90 percent of the people who use dishwashers usually do some level of rinsing before loading.

But most of the new machines comprise a soil sensor to check for debris and cloudy water. So pre-rinsing is not needed unless your dishwasher is very old. 

So, if you do a pre-rinse, your dishwasher can be good off. And leave your dishes with stuck-on food and stains. And more importantly, you’re wasting water and your time.

Dishwashers are also capable of spraying highly controlled jets of water upwards of 60 degrees Celsius (140 Fahrenheit) at the dishes,

And this is something that our human hands can’t handle – although experts recommend you only need to set it as high as around 48 degrees Celsius (120 Fahrenheit).

But this is not just all about clean dishes some people prefer hand washing as a meditative act they like to feel the hot water and dishes in their hands.

Some just enjoy it as they don’t have more dishes to wash in a small family. It’s a very human trait to think that machines will never be able to replace our skills no matter how advanced the technology is.

A dishwasher was built many years ago, and many of us still do our dishes ourselves, or at least take the time to pre-wash them before loading them into a dishwasher.

But as we have discussed above modern dishwashers are now officially faster, more hygienic, and way better for the environment than we’ll ever be.

So maybe the time has come now to give in and let the machines do the job. And make sure the items you are washing are dishwasher-friendly.

And if you want to do hand-washing it’s completely fine. There is nothing wrong with scrubbing your dishes. But that method may not fully sanitize your dishes.

But the dishwasher is also not appropriate for those who live alone and have a rotation of the same three to four dishes each day,– unless you don’t mind using it occasionally.

Practices For Hand Washing

You can fill one side with hot water if you have a double-sided sink, and use the other side as a rinse bath. And if possible don’t let the water run when you wash. Finish off the glassware first and then you can carry on with plates and silverware. And in the last finish with pots and pans.
