Dishwashers ‘more of a lifesaver than expected’ — 5ch: ‘Pre-rinsing is just a quick rinse, so easy’

From our other sites

The story

A thread appeared on 5ch’s Newsoku VIP board where a poster reported that after starting to use a dishwasher, it turned out to be ‘more of a lifesaver than expected.’ The original poster bought a secondhand countertop model for just a few thousand yen and says cleanup after cooking pasta became dramatically easier. Replies poured in with the questions everyone wonders about before buying one: whether pre-rinsing to remove oily grime is really necessary, how people find space to install the thing, and whether it’s big enough inside to fit large cookware like frying pans. On the other hand, there were also skeptical takes like ‘if you still have to pre-rinse, what’s the point’ and ‘you can just wash things between cooking steps,’ sparking a debate over how much dishwashers actually streamline housework.

Does it actually get stuff clean even when it's covered in greasy oil? (´・ω・`)
7AnonymousSep 1, 2026 16:31
Do you need to pre-rinse?

Re: #6
Yeah, it does.
Re: #7
I just rinse off any big leftover food bits before putting stuff in the dishwasher
after that it cleans itself.
Re: #8
Wait, it needs maintenance?
Didn't know that.
8AnonymousSep 1, 2026 16:31
Even if it's fine to be sloppy about it, you still need to pre-rinse, right?
The main reason I hesitate to buy one is the maintenance you have to do at practically a daily level.

Grease that's cooled and hardened is surely a lost cause though.

Re: #10
Maybe so.
Don't know.
Re: #11
Next to the kitchen faucet.
But in my house's case, I ended up needing a small extra table for things like cutting boards.

What do you do for space to put the dishwasher?
18AnonymousSep 1, 2026 16:37
So how many ten-thousands of yen are we talking? (´・ω・`)

I got mine secondhand on Amazon for 6,000 yen.

Re: #23
Is this actually big enough to fit a frying pan?
29AnonymousSep 1, 2026 16:45
It's a secondhand AQUA Dishwasher (White) [Dishwasher] [With Air-Drying Function], model AQUA ADW-GM (ADW-GM1-W), but it looks like now you can only find it for 15,960 yen.

Wouldn't want it even for free…

If you still need a rinsing step, it's pointless!
34AnonymousSep 1, 2026 16:47
Re: #30
No but seriously, it's so much easier.
35AnonymousSep 1, 2026 16:48
Re: #34
Sure, if you don't need a rinsing step.
If you can just chuck stuff in.
But you do need it, don't you?

Re: #35
I do give big leftover bits a light rinse with water, but it might not be strictly necessary.
Can't speak for how other people use theirs, though.

Robot vacuums are great too.
Who knew cutting down on housework felt this good.

Re: #36
There was a guy whose 'occupation' was literally 'minimalist,' and the only things he owned at home were (an AC unit and) a robot vacuum.

Re: #52
Well, I won't force it on stubborn people, but I was honestly amazed at how much easier it makes things.

It's genuinely great when I make pasta.
The frying pan, colander, pot, fork, and plate all get clean on their own.
63AnonymousSep 1, 2026 17:04
Some people ask 'what about the frying pan?' but I wash cookware like that between cooking steps anyway.
Too many people can only think in all-or-nothing terms.
Just washing the dishes after a meal in the dishwasher —
even just that alone saves a decent amount of time.

Re: #63
That's unfair to say.
I've had chronic 'housewife's eczema' (dishpan hands) that won't heal for years, so I can't wash dishes without gloves — which means washing just the frying pan while cooking isn't an option for me.
That's why, if I'm going to pre-rinse at all, I just end up doing the whole wash right then.
I'm not against dishwashers at all, though somebody in here is acting unhinged.
The dishwasher I own doesn't fit a frying pan, so I ended up not using it anymore, but if it fit I'd probably still be using it.

Re: #75
Didn't you make a thread about this before?
That's the Panasonic single-person dishwasher, right?
It was your thread that made me decide to buy a dishwasher, and I did.

Re: #75
LOL that's tiny.
87AnonymousSep 1, 2026 17:16
If you cook normally, the dishes pile up fast — not just the frying pan, but mixing bowls, pots, ladles, the rice cooker's inner lid, colanders, cooking chopsticks, measuring cups. You can usually wash most of that between cooking steps, but not having to wash the dishes after a meal — think about how much that benefits time-strapped modern people.

Re: #87
I used to think anyone who 'needed' a dishwasher was just too clumsy to wash things while cooking, but coming from someone who clearly gets it, that changes things.
A dishwasher… might actually be worth it.

Re: #87
The contradiction of someone with no time to spare… cooking.

Guess I'll make some pepe-tama pasta (a quick pasta dish with egg) for dinner tonight.
Thanks to the dishwasher, making pasta feels so much easier now.

Dishwasher threads and front-load washing machine threads always turn into a fight without fail — it's kind of funny.

Re: #136
Didn't expect it to blow up this much.
144AnonymousSep 1, 2026 18:05
Re: #136
Seriously, what even is this phenomenon?
Does it touch on some kind of complex people have?
If so, it's weird that people single out countertop models as the enemy, though.

Background and Key Points of This Discussion

Countertop dishwashers that require no installation work and can simply be placed in the kitchen are widely available at low prices, and it’s not unusual to find secondhand units for just a few thousand yen. In the thread, real examples came up too, like one bought secondhand for 6,000 yen and another for 15,960 yen. On the other hand, many models have small interior capacities that can’t fit frying pans or pots, and as pointed out in the replies, the hassle of pre-rinsing and securing installation space tend to be hurdles before buying. Where opinions in the thread diverged was over how much benefit people actually feel from a dishwasher — those who want to offload housework entirely clashed with those who feel it’s enough to just wash things bit by bit between cooking steps. Note that the later part of the thread devolved into an exchange of personal attacks over people’s experiences using it; this article focuses only on the exchanges related to the product and how it’s used.
