I disagree with the energy use you don’t necessarily have to use hot water. And the costs differ if water is heated with gas. To gloss it over that proves your conclusion to be moot. Hand washing for us is a big cost saver on energy

[@edthelazyboy]

The time and effort savings alone makes it worth it. I've had people argue with me that they can finish washing the dishes by hand faster than my dishwasher's 2 hour cycle. I counter by telling them that I only spend time loading and unloading the dishwasher. The dishwasher's working time isn't using my own time. I am free to do other things while it works.

[@DrBoom88]

Exactly. The time the dishwasher takes (compared to doing it by hand) is only relevant if you need clean dishes right this minute.

That means you have two minutes of running the water to rinse the dishes, assuming you don't pre-rinse or have any need to top off the basin, before you're using as much water as the dishwasher. There's definitely a tipping point for loading in too few dishes for the dishwasher to be worth it but most people understand that a single plate would be a waste.

Did you watch this video, and are frustrated because you live in a place without a dishwasher, or without a place to even install one? Look up a countertop dishwasher! I got a Faberware personally. It requires no installation, fits on my counter without issue, takes maybe 5 minutes to load, and saves me many hours every week.

1. To fully compare efficiency, also compare the amount of labor involved. The main reason why people buy dishwashers is to reduce the time spent on a repetitive & boring chore. I wanted to write "You had me at time-saving" but it wasn't mentioned. 2. It would help some of us if you also compare older dishwashers, not just "modern." I think mine is 50 years old. It doesn't heat the water, and the hot water supply in the building is set at about 125ºF. Perhaps MinuteFood should do a video about whether to replace an old dishwasher (that isn't broken).

[@VeteranVandal]

In your case, the water isn't hot enough, so it won't be very effective. If it has the heating element and it's broken, fix it, if it doesn't have, a tabletop dishwasher or getting an electric hot faucet and use that water instead are options. Or buy a new dishwasher and sell yours for someone with very hot hot water.

[@stephenlee5929]

125F, is about 52C, UK dishwashers run between 51 & 60C, so 52C should be do able, maybe not ideal but useable. Worth checking that the water is running hot before running the dishwasher, ie if the hot feed is next to your hot tap (faucet), run that 'til it's running hot, then start you dishwasher.

[@NaThingSerious]

If your dishwasher is 50 years old (although I doubt that, as the chances of it not needing replacing due to breaking or whatever are very slim) then I would highly recommend replacing it. Technology has improved, safety standards have improved, a newer dishwasher will clean dishes much better, and will likely use much less water and energy due to more modern energy and water saving methods.

[@brothermine2292]

>NaThingSerious : On the other hand, a rule of thumb is to not replace large appliances that still work. Besides the obvious time & money costs to research, buy & install a new unit and to dispose of the old unit, manufacturing processes consume resources and generate pollution. Also, newer appliances tend to break down more quickly because they're not built to last.

[@stephenlee5929]

@@brothermine2292 I tend to agree, if it does what you need/want, probably no need to change. If its not doing what you want/need, can it be made to do that? If so at what cost? Having said that, if you look at older cars, for instance, newer cars tend to give much better comfort, safer drive, safer in accidents, these happen even if not your fault, cheaper to run. Sometimes it is worth considering an upgrade. Re new stuff being not built to last, I think it is worse I think it is often built not to last. Washing machines are very simple machines really.

Things worth noting. It’s worth scraping solid foods off, but you don’t need to pre-rinse in the sink before going into dishwasher. ALSO, not all things SHOULD go in a dishwasher: certain plastics that deform in high heat, wood utensils that can be ruptured from the high heat, and vacuum sealed containers may not hold their vacuum. SO, THOSE items should be hand-washed just before you run the dishwasher to allow the water to warm up before running the dishwasher. ALSO, on a similar note, I LOVE that this video spoke out about the germ /water temperature while hand washing topic; “washing water with extremely hot water” to kill the germs is sooooo wrong - just use water warm enough that it feels comfortable for you hand - you will NEVER want to warm the water up enough to the point that the hotness kills germs, at that point you are scalding you are hand.

There’s generally 4 steps. Add a water supply, add a drain, add power cable, and put it in place. I only needed an adjustable wrench, a Philips head screw driver and a flathead screwdriver for my own and a drill bit. After doing mine I did another for my girlfriend’s house and that one only needed a 1/4 hex nut driver instead of a flathead. I also wasn’t able to turn off the main water supply to get a different valve for the dishwasher, so I added a T fitting so both the sink water and the dishwasher supply are operated by the same valve

[@ericeaton2386]

I'm generally pro-dishwasher, but I feel the need to point out that sanitizing is not the same as cleaning. There are times when the dishes may be sanitized (from long exposure to hot water), but not clean (from crusted on food). The fact that sometimes dishes may come out not completely clean, even if they are sanitized, is a major component of feeling like dishwashers are inefficient.

[@gongcyclist]

This all the way. If you are doing real cooking, and end up with crusty pots and pans, you can’t just throw them in the dishwasher and walk away. You have to stand there and scrub the crap out of them repeatedly until they are clean of crud, and at that point where they’re ready to go in the dishwasher, they’re basically done anyway. If someone is happy with the results of their dishwasher, I’m convinced they don’t cook. They’re just sticking something on a plate. But if you actually cook, the dishwasher is not saving you any time, because you have to stand there washing only to have the dishwasher wash it again. Now, the sanitizing power of hot water is a valid point, and probably the only convincing argument in this video. If we change the name of a dishwasher to dish sanitizer, I could probably get behind it. And this is probably the crux of the pushback. If you the thing does not *wash* your dishes, then it is not a dishwasher. When it can scrape the crud off of grandma’s turkey pan the day after Thanksgiving, it will be a dishwasher. Until then it is a dish sanitizer.

[@F8isRIPPIN]

Just soak them in water for an hour, crust gone.

[@lekhakaananta5864]

@@gongcyclist Sounds like this depends on the type of cooking and cookware though. I've cooked with pots and pans and even though the dishwasher can't reliably get rid of all the food crust, it's still a very useful tool. Here's why: 1) It almost always works reliably on dishes 2) For cookware, you might want to manually pre-wash and judge with your personal experience. For me, it's still faster to quickly scrub off big chunks of crust and then load it into the dishwasher, than to do everything manually to the end. If you have like 5 pots from a big meal, going all the way to completely clean for each piece might take you several additional minutes. So much easier to scrape off big crusts and leave the rest to the machine. 3) In my experience, even if a pot comes out of the machine with food crust still on it, it's wayyy easier to remove than trying to scrub it off before you put it into the dishwasher. The dishwasher seems to soften it up and remove large areas of crust; the remaining bits are small pieces that are easily wiped off manually. This probably has to do with the much higher water temperature you get from doing it with the machine first, and several hours of detergent exposure. It's like soaking your pots before washing, but even better!

[@iang0th]

@@gongcyclist If you cook, you ought to learn some cooking techniques that will greatly reduce the cleaning you have to do. For instance, you can make a gravy with the drippings in that roasting pan, which will basically clean the pan in the process (the leftover gravy can easily be rinsed out by a dishwasher). Pan sauces in general serve the same purpose. For baking, lining things with parchment paper is often a good way to keep the food from sticking to the pan. Maybe not everything you want to cook will make your dishes easy to clean, but you can have a pretty full repertoire of dishes which do.

[@OfftheRadar9790]

Really, my biggest reason for pre-rinsing isn't because it cleans dishes better per se, but because a dish might sit in the dishwasher for several days before the dishwasher gets full enough to run. Any crumbs or food residue on those dishes in that time just sit there rotting, or worse, attracting bugs. I have actually had ants infest my dishwasher before. Get this, just running the dishwasher does next to nothing to get rid of ants. So it's not about cleaning the dishes better, it's about preventing food from being left out.

The catch here is that dishwashers are going to completely blow handwashing out of the water for removal of pathogens, but handwashing will be better for at least some forms of caked on dirt, and the latter is what is visible and generally judged as clean vs dirty day to day. It's an increasingly small difference, particularly when you mix in all the mistakes people make that are easily fixed to get better performance here, but it could explain why people *perceive* handwashing as better.

[@icedragon769]

Yeah, but the nice thing about using the machine for everything by default is that exposes those few cases where you do need to put in some extra effort, so that you can expend that effort WAY more economically. Instead of hand scrubbing every single bowl you ever use on the off chance that the dishwasher might not be able to clean it, you see a little crud that you need to scrape off with a fingernail and a brush once a month or so. Seconds of manual effort vs hours. Refusing to use a dishwasher and washing everything by hand because it sometimes leaves on gunk is like refusing to vacuum and rug-doctoring your floors every week because it doesn't pick up stains.

Do you use pre wash detergent? Every dishwasher is designed to use two doses of detergent, for its two main cycles. The pre wash cycle water gets drained pretty quickly because its the first to go and its the cycle that deals with dishes that are the most dirty. If you dont put detergent in for that cycle, the cycle essentially just gets the dishes wet. Also check to make sure that the water coming from your kitchen sink is hot before turning on the dish washer. If it isnt, whenbyou turn it on the pre wash cycle will be washing with cold water. Do both of these things. Put in some detergent just at the bottom of the dishwasher, literally just throw some in there and then run the sink hot. This will make sure that the pre wash cycle is using hot soapy water instead of cold non-soapy water like its probably been doing. Once the prewash cycle water is drained, the main wash will only have to deal with somewhat dirty dishes and will have a lot more soap to wash them with.

[@NevisYsbryd]

​@@brothermine2292 It depends on the foodstuff in question. Generally, no, not to the point that a dishwasher alone will remove it. Soaking can drastically reduce the amount of scrubbing necessary to remove it, though. Cheese, baked goods, anything involving egg can be really obnoxious to remove, especially if you are _cooking_ rather than warming something on a bowl/plate. I spent a year as a dishwasher and eggs and bacon sheets were by far my least favorite things to clean.

The problem with the cleanliness studies is the endpoint. No one is swabbing their dishes at home and sending them for bacterial cultures to judge if they are "clean". People judge cleanliness by food residual left on dishes. If the dishwasher always leaves some food stuck on, people are not going to consider it clean. Therefore they will hand wash instead to make sure they can directly remove any bits of food.

My dishwasher very rarely leaves any pieces of food stuck to it. When it does, I simply remove it by hand knowing that it’s still a clean dish because of how hot the water got.

Trying to be environmentally conscious is sometimes worse for the environment. Those "brown natural" sponges might have been made from sea sponges, which were nearly overfished to extinction. And the fishing could have contributed more carbon emissions than the manufacture of plastic sponges, similar to how a cotton shopping bag creates hundreds of times more carbon emissions than a single-use plastic bag, so you have to use it for years before it's beneficial for the environment. I'm not saying that plastic sponges are great for the environment either, but these things are never as simple as they seem at first. I'm only guessing, but maybe a luffa (sponge gourd) would be the most environmentally-friendly option?

It only makes no sense to not use a dishwasher if you have enough dishes that need cleaning. Not only do I live alone, I use a pretty small set of dishes daily: two plastic bowls, a multicooker bowl/pan, a tablespoon, a teaspoon, a fork, a mug, and a knife. Plastic dishes and knives are recommended against being put in a dishwasher, the former can deform because of the heat, and the latter can get dull; the multicooker pan will probably not even fit in one, and I'm sure it's not allowed to go in it either. I have literally zero reason to buy a dishwasher for two spoons, a fork, and a mug.

[@michahalczuk9071]

​@@Lernos1 Well in that case: 1. Buy a real set of dishes and fill up dishwasher once every couple days. 2. Knives don't go dull in dishwasher - this warning is either from knives having untreated wooden handles that get damaged by water or weird japanese knives made of iron/carbon steel that rust easily. There is literally nothing else contacting knife than hot water solution with detergent soluable dirt. Or buy a mini dishwasher - they're still more cost effective than handwashing.

But in my case, I have a few plates, a few bowls, a bunch of old glass containers/ jars I use as drinking glasses, some cups, a set of utensils etc etc etc). Which means I don't need to wash most dishes immediately for me to have some clean ones the next day. I can just load up my machine and run it once it's full (which is almost exactly when I've used up all my dishes), and repeat the cycle. Now, even though I got the cheapest viable dishwasher available to me, I know that not everyone has the money, the space or some other capacity to get one.

Out of all people. The only reason to not use dishwasher is if you're stay at home parent priding yourself for doing unnecessary chores to fill the day, or if you have pans or other things that can't be put in the dishwashing machine. Washing dishes by hand as a student for 14 years has been some of the most miserable parts of my life. I got dishwashing machine at some point but had to move in a place that has too little room to remove a cupboard for dishwashing machine and it's expensive to install because it has to be made by a professional to apply for insurance. Actually they just turn the water valve, you have to pay more for them to install it, you have to install it and pay for them to turn the valve. I don't know anyone who trusts their dishwashing machine so much that they wouldn't pre-rinse. Even with pre-rinsing you can sometimes find food scraps on the dishes. I guess "not necessary" is everyone's subjective experience.

Why do some dishes (especially plastics) have residual detergent fragrance after going through the dishwasher? Are there detergent/rinse aid residues on dishes?

[@insu_na]

Metal and Ceramic dishes are non-porous, plastic dishes are generally porous, so they will retain some of the cleaning chemicals

[@heychrisfox]

Sometimes. It really depends on which soaps you're using, how hot the water is, among other issues. If you have residue, consider switching soap to either a different brand, or a less concentrated formula for a little while and see what happens. As for the rinse aids, it SHOULDN'T leave residue, so if you're concerned that's what's causing it, I'd save testing the removal of that for last. Two other tips! Make sure that the water in your dish washer is actually hot. Cold water circulating is less likely to get gunk off than hot water. Secondly, make sure you're not overloading your washer, or stacking dishes strangely. If some plates/bowls are overlapping, and water can't rinse that particular dish, then the residue is gonna stay there.

[@tjiddenl]

Putting plastic in dishwashers isn't recommended. There was a big study on plastic water bottles in The Netherlands and it showed after 15 washes in a dishwasher it started to drop micro plastic. Which can't be healthy for you. Because they get to hot. Besides that, non plastic silverware is usually more robust which leads in less waste.

[@ductng]

I am all in for using a dishwasher, but what about the environmental impact of dishwasher detergent? I guess it goes roughly along with the water usage (i.e. hand washing uses more water, hence also more soap), but how much more aggressive is dishwasher detergent than normal soap?

[@dragofand]

It should be around the same amount of impact as normal soap, but you're likely using less detergent in the dishwasher. Main thing about dishwasher detergent vs normal dish soap is that the dishwasher detergent just doesn't foam up. If you are concerned though, consider using powder instead of something like a detergent pod. The pods can only be deployed during the wash cycle, so they're typically more powerful and more concentrated. Whereas the powder you can more easily choose how much detergent you add.

[@NYKevin100]

It depends on the choice of detergent. If you're using the powder or tablets, it probably contains bleach, which is not exactly a nice chemical to deal with, but it's mostly a problem for people with septic systems rather than municipal sewers. Septic systems are affected because they depend on bacterial activity to function, and bleach kills bacteria. In a municipal sewer, most of the bleach will break down into simple compounds like table salt and water, but there is evidence that a small portion may form chlorinated organic compounds, which could be carcinogenic in large enough quantities (more research is needed). If you're using the goop, then there's probably no bleach in it, just soap (surfactants) and enzymes. I find it hard to believe that the enzymes used in dishwashing will survive wastewater treatment, but surfactants may have environmental effects. Those chemicals are also present in the powder and tablets, and some kind of surfactant will be present in basically any means of washing anything (dishes, clothes, hands, the body, etc.), so it's not as if this is avoidable (but maybe we can find surfactants that cause less harm). As for hand-washing dish soap, you're likely to find surfactants and possibly something like lactic acid (to kill bacteria and/or descale surfaces), which again can have implications for septic systems if used in large enough quantities, but seems unlikely to cause broader environmental issues (lots of animals produce lactic acid naturally as part of their metabolism).

[@fuzziestlumpkin]

This is actually a good point. Especially with tablets and capsules... the soluble film they are wrapped in has a warning along the lines of "toxic to fish and aquatic life". Good thing there's no way for it to end up in natural water courses! (I'm British and that was sarcasm)

[@heychrisfox]

@@fuzziestlumpkin With regards to the toxicity, that's mostly in its pure, concentrated form. So basically, don't toss one of the pods in the river; if a fish eats that, it'll die. However, once the pod is in the wash, it completely breaks down in the water, and just lets all the soap out. That mixture will not only be extremely diluted, but will just be sent out with sewage anyway, to be processed later, so there's no real environmental impact any more than other types of soap.

Unfortunately people don't like this option and I understand why, but I designate a counter for dirty dishes and the dishes that sit inside my dishwasher are clean. Dishes sitting on a counter get dry really quickly, which means they dont smell or attract insects. I live alone and go weeks in between cycles with no problems. Another option is to buy a dishwasher with an air purifying system, such as the beko ionguard system, but I dont depend on it for dirty plates

It might still be more water effective to run the dishwasher more often, like when it's 1/3 to 1/2 full, than to pre rinse each dish and only running at full capacity

I never prerinse and I agree, sometimes stuff stinks. Leaving the door ajar greatly helps, also I use a napkin to remove food residue

[@crimsonraen]

Thanks for the video! We always use our dishwasher, unless it's something we have few of, but use very often. This is a good reminder that we don't need to pre-rinse the dishes though!

Measuring cleanliness with the amount of bacteria feels weird to me. I think how much food is stuck on the plate or how much oil is left on the plate are better measures because bacteria can grow from these leftovers.

[@megawonszrzeczny9]

They have to measure it that way, because most of the time oils/leftover food gets removed by either a dishwasher or by a human completely, since you can see it. You can't see bacteria, which is probably why it's still there after humans wash dishes. A dishwasher doesn't need to see the dirt, because it's washing the dish x times no matter how dirty it looks, which is probably why there is almost no bacteria after a full washing cycle.

When I cook and prepare dinner and lunches (I do most of the heavy lifting part of making the next day's lunches for the four of us, two kids and two adults, in the hour or two I spend in the kitchen making meals) handling washing everyting but the dining ware is part of the process. After dinner, the kids take turns drying and putting away the cook ware then washing the dinner ware which everyone has left their own rinsed off and placed in the dish pan and washed their own cups and/or glasses. When which ever kid is washing the dishes, I take the opportunity to visit with them while I detail some part of the kitchen.

Here is a question. Who fonded those researches? Dishwasher makers?

References in the description, you can check yourself, funding has to be disclosed :)

If you run your dishwasher before it is full because you are worried about the smells and such - Check if your dishwasher has a quick-rinse program. Ours does, and it really helps. It does just a single cycle, equivalent to the prewash, and gets rid of a lot of the gunk already. As a result, the dishwasher doesn't smell bad nearly as fast. You can do a quick rinse after filling it half up, buying you an extra day or so to fill it completly!

- dishwashers can't remove crusts and sticky food - those studies usually use very stupidly resource-intensive handwashing techniques (leaving the sink fully running at all times, always using soap (it only removes fat, so no point in using it in many situations)…) - washing dishes before the filth has time to cool or dry is much easier and more effective, but can't be done if you have to gather a full load for a dishwasher - the manufacturing process of the dishwasher and of the extra dishes to make it worthwhile is usually unaccounted for

[@sectorcodec]

What’s your counter to the fact that handwashing dishes still leaves them full of germs? Sponges which you are wiping dishes with are some of the most bacterially active places in your entire house, same with towels. You’re wiping dishes with bacteria the entire time you’re cleaning them by hand.

[@yjlom]

@sectorcodec I eat food off the floor sometimes

[@MikeU128]

After watching a few of your videos, I think you have our exact (or nearly so) dishwasher and fridge/freezer. Maybe the microwave too. Now I want a GoPro to see if the upper spray arm on our dishwasher is clogged like yours! I hand-wash my water/beer glasses because I don't like the smell of dishwasher detergent on them. But I also spray them with an iodine-based foodservice sanitizer (which evaporates, so you don't have an iodine smell unless you use them immediately after washing).

[@jobo5300]

The biggest difference: TIME.Washing dishes by hand simply takes a lot of time you can use for other things. When free time is already at a premium for you this begins to matter a lot.

[@gladitsnotme]

This is why I use my dishwasher even for smaller loads. 5 coffee mugs, a popcorn bowl, some tumblers and a baking pan are my typical load and I know I'm saving water and time.

[@Roxor128]

Ugh! Sure does. It's maybe 15 minutes to solve the puzzle of loading the dishwasher, and about 45 for the tedious chore of washing the same amount by hand.
